                                          WAIVER REQUESTS

        Pursuant to Section 1.3 of the Commission’s rules, the Commission may waive its rules

for good cause shown.1 “Waiver is appropriate if special circumstances warrant a deviation from

the general rule and such deviation would better serve the public interest than would strict

adherence to the general rule,” including “more effective implementation of overall policy.”2 In

determining whether waiver is appropriate, the Commission should “take into account

considerations of hardship, equity, or more effective implementation of overall policy.”3 As

shown below, there is good cause for the Commission to grant a waiver of Sections 25.202(a)(1),

25.202(g)(1), 25.157(e), 25.164(b), 25.208(e), 25.145(c)/25.146(i), 25.146(a), and, to the extent

necessary, any restriction in Section 2.106 on SpaceX’s proposed use of the 17.8-18.6 GHz band

and various limitations in the Commission’s Schedule S.

      1. Waiver of Gateway Restriction in Section 25.201(a)(1) for the 10.7-11.7 GHz Band

        SpaceX requests a waiver of the Commission’s policy of authorizing only gateway

earth stations in the 10.7-11.7 GHz band.4 SpaceX proposes to operate its user terminal earth

stations in this band on a non-conforming, non-interference, non-protected basis.5                           In

considering requests for non-conforming spectrum uses, the Commission has indicated that it

would generally grant such waivers “when there is little potential for interference into any

service authorized under the Table of Frequency Allocations and when the non-conforming

    The Commission has granted a similar waiver in the past. See, e.g., PanAmSat Licensee Corp., 20 FCC Rcd.

operator accepts any interference from authorized services.”6

        SpaceX’s request satisfies both of those conditions. The SpaceX System’s satellite

downlink transmissions in the 10.7-11.7 GHz band to these earth stations will comply with the

Commission’s power flux-density (“PFD”) limits as demonstrated in Section A.7 of the

Technical Attachment. These PFD limits are intended to protect terrestrial Fixed Service

(“FS”) systems from potential interference from satellite downlinks, and the Commission has

determined that meeting such limits is sufficient for this purpose.7 In addition, the SpaceX

System’s receiving earth stations will not seek any interference protection from FS

transmissions, and so their operation will not constrain the further development of that service

in this band.

        There are several sound technical reasons to support the use of SpaceX user terminals

in the 10.7-11.7 GHz downlink band on a non-protected basis with respect to the FS, as

follows:

       Directionality:        The potentially interfering FS transmitters typically radiate in a

           horizontal or near-horizontal direction using narrow beam antennas.                         SpaceX

           receiving user terminals only have significant gain in high elevation directions and

           low gain towards the horizon, because the SpaceX System is designed to provide

           service to user terminals at elevation angles at or in excess of 40 degrees. As a result,

           a SpaceX user terminal will have sufficient separation distance from the highly

           directional FS transmit antennas in this frequency band.                     In addition, further

    service to fixed terminals in bands allocated to the mobile-satellite service).

    “power flux density (‘PFD’) limits for NGSO FSS in the 10.7-11.7 GHz band are sufficient to protect services
    in the band without the need for individual coordination”).

         angular separation may be gained based on the physical siting of the FS transmitter

         and SpaceX user terminals. FS links tend to be located on towers or relatively tall

         buildings, with a “local” horizon of tens or hundreds of feet above the ground. In

         contrast, most SpaceX user terminals are expected to be sited closer to the ground,

         adding separation between the transmit FS site’s main pointing direction to the

         receiving FS site, and a given victim SpaceX user terminal.

      Wide Downlinks: The SpaceX user terminals receive downlink transmissions of

         around 250 MHz bandwidth, wider than any likely interfering signal from an FS

         transmitter, which are typically no wider than 40 MHz. This will further reduce the

         effect of the interfering FS carrier.

      Alternate Bands: In the unlikely event of problematic FS interference in the 10.7-

         11.7 GHz band for service at a particular user terminal location, SpaceX has the

         option to transmit to user(s) at that specific location predominantly in the 11.7-12.2

         GHz band, which is not shared with the FS.

      Repositioning:       Where necessary, SpaceX can also achieve further interference

         mitigation for an affected user terminal by repositioning a given user terminal to

         another side of a natural or man-made obstacle (e.g., a building) to block the

         interfering FS signal.

Accordingly, the Commission should grant the waiver and authorize SpaceX to operate its user

terminal earth stations in the 10.7-11.7 GHz band on a non-conforming, non-interference, non-

protected basis.

       2. Waiver of Section 25.202(g)(1) for TT&C Operations in the 13.75-14.0 GHz Band

         Section 25.202(g)(1) anticipates that satellite systems will conduct telemetry, tracking

and command (“TT&C”) operations using spectrum at the edge of or within their assigned

bands.8 SpaceX proposes to conduct its TT&C uplink transmissions using a portion of the

13.75-14.0 GHz band – specifically, 13.85-14.00 GHz. This spectrum is at the upper part of the

13.75-14.0 GHz band, which is included in the ITU network filings made on behalf of SpaceX

but not included in the bands for which authorization of communications transmissions has been

sought in this application. This band is also immediately adjacent to the 14.0-14.5 GHz band

used by the SpaceX System for user terminal uplink transmissions. To the extent necessary,

SpaceX requests a waiver to permit its use of this spectrum for TT&C.

         The Commission has restricted FSS deployment in the 13.75-14.0 GHz band to gateways

only, which it has specifically defined to include TT&C operations.9 In addition, under footnotes

to both the U.S. and international frequency allocation tables, NGSO FSS earth stations

operating in this band must have a minimum diameter of 4.5 meters and the EIRP of any

emission should be at least 68 dBW and should not exceed 85 dBW.10 The SpaceX System will

comply with these requirements, and will not claim protection from radiolocation transmitting

stations operating in accordance with the U.S. Table of Frequency Allocations.                             SpaceX

anticipates that it will provide TT&C from only two locations in the U.S. (on the East and West

Coasts, respectively), which will further minimize any potential impact.

       3. Waiver of Band Segmentation Requirements in Section 25.157(e)

         In response to the filing of an application for an NGSO system, the Commission has

initiated a processing round for competing NGSO system applications pursuant to Section

25.157 of the Commission’s rules.11             In such a processing round, the Commission’s rules

establish certain band segmentation procedures if there is not sufficient spectrum available to

accommodate all qualified applicants.12 However, band segmentation appears to be inconsistent

with the “avoidance of in-line interference events” approach that the Commission adopted for

Ku- and Ka-band NGSO systems over a decade ago and which was recently reaffirmed as

applicable by the International Bureau.13 For the reasons discussed below, SpaceX submits that

the in-line avoidance approach would better serve the public interest and requests that the

Commission waive the band segmentation requirements of Section 25.157(e) to the extent

necessary.

         The Commission considered various approaches for intra-service sharing among NGSO

FSS applicants in the Ku-band when it adopted the Ku-band NGSO Sharing Order in 2002.14

The four approaches considered were (1) Flexible Band Segmentation; (2) Dynamic Band

Segmentation; (3) Avoidance of In-line Interference Events; and (4) Homogeneous

Constellations.      The Commission preferred the Avoidance of In-line Interference Events

approach, under which all NGSO FSS licensees could use the entire Ku-band spectrum at issue

     for avoidance of in-line interference events for Ku-band NGSO systems would be applied in the same manner
     as they are for Ka-band systems under Section 25.261 of the Commission’s rules).

     See Establishment of Policies and Service Rules for the Non-Geostationary Satellite Orbit, Fixed Satellite

     band” refers to the 10.7-12.7 GHz, 12.75-13.25 GHz, and 13.75-14.5 GHz frequency bands.


                                                        5


except in situations where multiple NGSO systems experience in-line interference, when they

would have to coordinate.15 The Commission found that this approach would best meet its goals

of allowing equal access to the available spectrum, avoiding spectrum warehousing, and

encouraging system flexibility to promote spectrum coordination.16 In doing so, it explicitly

rejected the two approaches that applied band segmentation, finding that they “are overly

restrictive, and could result in insufficient spectrum for commercially viable operations.”17

Although the in-line avoidance approach was never codified in the Commission’s rules, the

International Bureau has recently clarified that this approach will continue to be applied to

NGSO authorizations.18

         A year later, the Commission considered the same four options and came to the same

conclusion when it adopted the Ka-band NGSO Sharing Order:                              an approach requiring

avoidance of in-line interference events would best serve the public interest.19 The Commission

found that satellite system operations in the Ku- and Ka-bands would be “quite similar,” and that

therefore the adoption of similar sharing rules would be “operationally appropriate and offers the

benefit of administrative efficiency and may enhance the development of technology applicable

to both services.”20 It once again rejected the two band segmentation options. The Commission

codified this sharing approach in Section 25.261.

           During the period between adoption of the in-line avoidance approach for Ku-band and

Ka-band NGSO systems, the Commission revised its process for satellite licensing generally.21

Among many other revisions, the Commission adopted modified processing rounds as the

mechanism for resolving competing applications for NGSO-like systems, including the band

segmentation approach to spectrum sharing codified in Section 25.157(e).22 Yet in doing so, the

Commission saw “no reason to impose a band-splitting approach on the Ka-band NGSO

applicants if they believe that they can share the spectrum,” and specifically found that the then-

pending Ka-band NGSO sharing proceeding would “determine which licensing method is best

suited for the Ka-band NGSO applications.”23 Consequently, the Commission directed the

International Bureau “to award Ka-band licenses pursuant to the processing mechanism adopted

in the [Ka-band NGSO Sharing Order] proceeding.”24

           Since that time, all Ka-band NGSO FSS system authorizations issued by the Commission

have been conditioned upon compliance with the avoidance of in-line interference events

requirement rather than the band segmentation requirements of Section 25.157(e).25 Indeed,

although Section 25.261 by its terms applies only to specific Ka-band frequencies, the

Commission has applied this in-line avoidance sharing technique in other portions of the Ka-

band as well rather than applying Section 25.157(e).26 Moreover, the Commission has also

issued all Ku-band NGSO FSS system authorizations with a similar condition based on

avoidance of in-line events rather than band segmentation.27 The Commission went so far as to

issue a public notice to clarify “that the text in Section 25.261 for Ka-band NGSO FSS systems

also describes the same sharing criteria the Commission adopted for Ku-band systems.”28

         The Commission should not now revert to imposing the automatic band segmentation

approach upon the participants in this NGSO processing round. Rather, the Commission should

waive the band segmentation requirements of Section 25.157(e) to the extent necessary.

Successful coordination among NGSO systems will yield much more productive use of valuable

spectrum and orbital resources than would a simple band segmentation approach. To this end,

SpaceX has designed its system with advanced technology and operational flexibility to

coordinate responsibly and thus facilitate spectrum sharing.                 Only systems with inflexible

technologies pose a problem in this respect, which the Commission will need to address.

       4. Partial Waiver of Final Implementation Milestone in Section 25.164(b)

         Section 25.164(b) of the Commission’s rules provides that the recipient of an initial

license for an NGSO satellite system “must launch the space stations, place them in the assigned

orbits, and operate them in accordance with the station authorization no later than six years after

the grant of the license,” unless a different schedule is established by the Commission.29 The

Commission has established such milestone requirements for satellite system implementation in

order to deter warehousing, which in this context “refers to the retention of preemptive rights to

use spectrum and orbital resources by an entity that does not intend to bear the cost and risk of

constructing, launching, and operating an authorized space station, is not fully committed to

doing so, or finds out after accepting the license that it is unable to fulfill the associated

obligations.”30 The rules are intended to offset the incentives for warehousing that could harm

both competition and consumers, while also encouraging the rapid deployment of new spacecraft

and the optimal utilization of scarce orbital and spectrum resources.31

         SpaceX proposes to launch and operate a constellation of over 4,400 satellites, divided

into an Initial Deployment of 1,600 satellites and a Final Deployment of 2,825 satellites. Final

deployment of all of these satellites is not necessary to commence delivery of broadband

services, nor is it necessary to demonstrate SpaceX’s intention to utilize the granted orbital and

spectrum resources. Completing the full constellation over a six-year period would require a

launch cadence of more than 60 satellites per month, beginning on the day the Commission

grants a license. This is an aggressive pace even for a company like SpaceX, which has

demonstrated considerable launch capabilities.

         In these circumstances, the Commission should grant a limited waiver to apply its

implementation milestone requirement to the Initial Deployment of the SpaceX System, to the

extent necessary. A waiver structured in this way clearly would not undermine the purpose of

the milestone requirements, as it would not result in, facilitate, or encourage spectrum

warehousing.32 Within the time allotted for the Initial Deployment, SpaceX will manufacture,

launch and bring into service more satellites than any other company currently has in operation.

Additionally, it will begin providing commercial broadband services in the U.S. and globally

once it has deployed the first 800 satellites of its constellation (32 planes with 25 satellites per

plane), and continuously thereafter as additional satellites are launched and the constellation is

replenished. Designing, constructing, and deploying these assets will require a very significant

investment of resources – considerably more than reasonably sufficient to demonstrate that the

company is “fully committed” to bearing the cost and risk of operating its authorized system.33

       5. Waiver of the Downlink PFD Limits in Section 25.208(e)

       As shown in the Technical Attachment, the SpaceX System does not comply with the PFD

limits established in Section 25.208(e) for very low elevation angles using the flawed

interference calculation methodology applied in the rule.                    As explained in the Technical

Attachment, the calculation methodology was not designed for (and did not contemplate) larger

constellations, and assumes downlink energy from all satellites in operation, not just those that

are visible from a particular location that could meaningfully be expected to contribute to

interference to a terrestrial FS system.34 The methodology also fails to discount interference

from those satellites that are switched off at a particular time or designed not to serve a location

at such a low elevation angle. When the calculation methodology is revised to reflect more

reasonable operating assumptions for larger systems, it becomes clear that the SpaceX System

would not be expected to cause harmful interference into terrestrial FS systems that share the

band.35 Accordingly, the Commission should grant the requested waiver in recognition of the

technical limitations of the methodology underlying the rule.36

       6. Waiver of U.S. Table of Frequency Allocations and Ka-band Plan in the 17.8-18.6
          GHz Band

         SpaceX proposes to use the 17.8-18.6 GHz band for downlink transmissions from its

satellites to a relatively small number of gateway earth stations, and to use the 18.55-18.6 GHz

band for downlink transmissions to an even more limited number of TT&C facilities.

Internationally, this entire band is allocated to FSS on a co-primary basis.                          Domestically,

however, the Ka-band Plan37 adopted by the Commission and codified in the U.S. Table of

Frequency Allocations (47 C.F.R. § 2.106) is materially different. The lower portion of this

band, from 17.8-18.3 GHz, is allocated on a primary basis to FS, with no allocation for FSS.

While the upper portion of this band, from 18.3-18.6 GHz, is allocated to FSS on a primary

basis, a footnote in the allocation table limits its use to GSO systems only.38 Accordingly,

SpaceX seeks a waiver of Section 2.106 of the Commission’s rules to permit its use of this

spectrum on a non-conforming basis – i.e., on a non-harmful interference, non-protected basis

relative to any service allocated in the band.


35
     SpaceX has recently submitted revised ITU network filings for its system, and believes that the ITU will
     conclude that the system as revised complies with the relevant international PFD limits in Article 21 once it has
     had the opportunity to apply its analysis.
36
     To the extent necessary, SpaceX requests that the Commission also waive the parallel PFD provisions in Article
     21 of the ITU Radio Regulations.

     “Ka-band Plan.” See Rulemaking to Amend Parts 1, 2, 21, and 25 of the Commission’s Rules to Redesignate

       The Commission has previously authorized NGSO use of the 17.8-18.3 GHz band on a

non-conforming basis, based on the applicant’s showing that it would comply with all applicable

downlink PFD limits.39 As shown in the Technical Attachment,40 SpaceX will meet the PFD

limits at the Earth’s surface prescribed by the ITU to ensure that NGSO downlink transmissions

do not cause unacceptable interference to the terrestrial FS systems operating in the band.41 In

addition, because SpaceX gateways will receive in this band, their operations do not present a

risk of interference. In the unlikely event that FS operations cause interference to one or more

gateway earth stations, SpaceX will accept such interference and take appropriate measures to

prevent it from degrading earth station operations.

       With respect to the 18.3-18.6 GHz band, the Commission has allowed NGSO systems to

make similar non-conforming use of FSS frequencies in the Ka-band downlink allocated to GSO

on a primary basis where applicants are prepared to accept interference from primary operations

and can demonstrate that their proposed operations are not likely to cause harmful interference to

primary operations.42 SpaceX’s waiver request is consistent with these precedents. As shown in

the Technical Attachment,43 SpaceX will operate downlink transmissions in this band within the

downlink equivalent power flux-density limits (EPFDdown and EPFDis) developed by the ITU.44

The ITU considers an NGSO FSS system that meets these EPFD limits to be fully coordinated

with respect to any GSO FSS network, and any interference by the NGSO FSS system into the

GSO FSS network is acceptable.45

         As stated above, in considering requests for non-conforming spectrum uses, the

Commission will generally grant such waivers when there is little potential for interference into

any service authorized under the Table of Frequency Allocations and when the non-conforming

operator accepts any interference from authorized services. SpaceX acknowledges that it has no

protection against interference from U.S.-licensed FS and GSO FSS networks in these bands, and

its compliance with the relevant PFD and EPFD limits ensure that no harmful interference will

result from operation of the SpaceX System. Accordingly, waiver of the Ka-band Plan and the

U.S. Table of Frequency Allocations is warranted here.

       7. Waiver of Geographic Service Requirements in Sections 25.145(c) and 25.146(i)

          Section 25.145(c) and Section 25.146(i) establish geographic coverage requirements

 for NGSO systems operating in the Ka-band and Ku-band, respectively. They are essentially

 the same for both frequency bands, and require the applicant to demonstrate that:

      (1) the proposed system is capable of providing Fixed-Satellite Service on a continuous

          basis throughout the fifty states, Puerto Rico and the U.S. Virgin Islands; and

      (2) the proposed system is capable of providing Fixed-Satellite Services to all locations as

          far north as 70° North Latitude and as far south as 55° South Latitude for at least 75

          percent of every 24-hour period.

Once fully deployed, the SpaceX System will satisfy these requirements, as it will provide full-

time coverage to virtually the entire planet. The Initial Deployment, however, will cover most

but not all of the area required. Specifically, the Initial Deployment will provide continuous FSS

     See ITU Radio Regs., No. 22.5I. See also contactMEO, ¶ 26.


                                                      13


service from approximately 60º North Latitude to 60º South Latitude. This is sufficient to cover

the contiguous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, as well as the

southernmost areas covered by the rule. However, the system will not provide continuous

coverage to the northernmost areas covered by the rule (e.g., the 60º to 70º North Latitudes in

upper Alaska) until service from one of the more inclined orbital constellations is activated.

       SpaceX has requested above a partial waiver of the final system implementation milestone

such that it would apply to the Initial Deployment only. Although SpaceX fully expects to meet

all coverage requirements at Final Deployment, out of an abundance of caution, SpaceX requests

a corresponding waiver of the geographic service requirements for the operation of the Initial

Deployment specifically,46 to the extent the Commission deems such a waiver necessary.

       8. Waiver of Source Code Requirements in Section 25.146(a)

         Section 25.146(a) of the Commission’s rules requires each applicant for authority to

operate an NGSO FSS system in the 10.7 GHz to 14.5 GHz bands to demonstrate that its

proposed system will not exceed the validation EPFDdown and EPFDup limits specified in Section

25.208 of the Commission’s rules.47 Where a computer program has not yet been approved by

the ITU for this purpose – and no such program is available or approved at this time – Sections

25.146(a)(1)(iii) and 25.146(a)(2)(iii) require each applicant to provide to the Commission a

computer program for the EPFDdown and EPFDup validation, along with the source code and

executable file of the validation program. SpaceX has used commercially available EPFD

46
     The Commission granted a similar waiver to O3b Limited (“O3b”) permitting its Ka-band NGSO FSS system to
     access the U.S. market, finding that waiver was appropriate because “due to look angle constraints, there is a
     limitation on the northernmost and southernmost latitudes that can be served by its system.” See O3b Limited,
     Stamp Grant, IBFS File Nos. SAT-LOI-20141029-00118 and SAT-AMD-20150115-00004, at condition 14
     (Call Sign S2935) (Jan. 22, 2015). Thus, the Commission balanced the NGSO satellite operator’s constellation
     design decision with the policy desire to maximize coverage. To the extent necessary, it should do the same in
     this case as well.

testing software created by Transfinite Systems (“Transfinite”) to validate its EPFD compliance

showing, and has provided an executable copy of the latest version of that program. However,

for the reasons set forth below, SpaceX requests a waiver of the source code requirement in

Section 25.146(a).

         The Commission requires NGSO applicants to submit EPFD validation programs so that

it can evaluate the EPFD showing and ensure that proposed NGSO FSS systems comply with the

applicable EPFD limits designed to protect GSO satellite networks. Although the ITU has not

yet approved a computer program for determining compliance with the single-entry EPFDdown

and EPFDup validation limits, it has engaged two companies to develop such software –

Transfinite and Agenium.48 The Transfinite software is apparently nearing completion, and is

available to the public for purchase. Thus, the Commission will be able to use Transfinite’s

EPFD validation program to evaluate the SpaceX System’s compliance with the applicable

EPFD limits without the source code, and SpaceX will provide the Commission any assistance

that is necessary to enable its successful use.

       The source code of Transfinite’s EPFD validation program is the proprietary information of

that company, and SpaceX does not have access to that source code. Moreover, Transfinite

could suffer substantial competitive injury if that source code were made available to the public,

including its potential customers and competitors. Given that Transfinite’s source code is not

necessary for SpaceX to demonstrate, or for the Commission to conclude, that the SpaceX

System will comply with the applicable EPFD limits, a waiver would not undermine the

underlying purpose of Sections 25.146(a)(1)(iii) and 25.146(a)(2)(iii). Accordingly, SpaceX

requests that Commission grant a waiver of the source code requirement in those rules.

       9. Waiver of Limitations in Schedule S

         As required by the Commission’s rules,49 SpaceX has submitted with this application a

completed Schedule S, which contains certain technical information in a prescribed form. The

current version of Schedule S only recently became effective,50 and this is the first NGSO

processing round in which the new version has been used. SpaceX has found that it cannot

accurately describe its system in certain respects due to limitations in Schedule S itself. Below

we discuss four aspects of the SpaceX System that fall into this category as well as how the

Schedule S was completed in light of these limitations. To the extent necessary, SpaceX

requests that the Commission waive these aspects of Schedule S in light of these limitations.

         First, Section 25.114(c)(4)(v) requires both the minimum and maximum saturation flux

density (“SFD”) values for each space station receive antenna that is connected to transponders.

The concept of SFD only applies to “bent pipe” satellite systems, and thus is not relevant to the

SpaceX System. However, the Schedule S software does not allow an entry of “not applicable.”

Instead, it requires a numerical entry for SFD, which must be different for the maximum and

minimum values. In order to accommodate this requirement, SpaceX has entered values of “0”

and “-0.1” in Schedule S with respect to these parameters.

         Second, Schedule S requires that the maximum transmit EIRP density value for a beam

be greater than 0 dBW. However, the maximum transmit EIRP density for the Ku-band TT&C

downlink beams on the SpaceX System is a negative value:                        -6.67 dBW.       In order to

accommodate this limitation, SpaceX has entered a value of “0” in Schedule S with respect to

this parameter, and stated the correct value in its Technical Attachment.

       Third, Schedule S requires that the maximum PFD value for any given angle of arrival

for NGSO systems operating in the 12.2-12.7 GHz band be greater than -200.0 dBW/m2/BW.

Although the Schedule S instructions indicate that the permissible range for this parameter is

between -1000 and -50 dBW/m2/BW, the validation functions built into the form itself require

the higher minimum value of -200.0 dBW/m2/BW. The maximum PFD value for SpaceX’s Ku-

band TT&C downlink beam, identified on the Schedule S as TTD3, is -200.2 dBW/m2/4kHz at

angles of arrival between 0 and 1 degrees. In order to accommodate this limitation, SpaceX has

entered a value of “-200.0 dBW/m2/4kHz” in Schedule S with respect to this parameter.

       Fourth, SpaceX will provision to launch up to two extra spacecraft per plane to replenish

the constellation in the event of on-orbit failures. If a case arises wherein a spare is not

immediately needed, it will remain dormant in the same orbit and will perform station-keeping

and debris avoidance maneuvers along with the rest of the active constellation. Because these

spare satellites will not operate their communications payloads, and the TT&C facilities

communicate in turn with a fixed number of satellites at all times, the addition of spare satellites

will not affect the PFD and EPFD analyses for TT&C operations presented in this

application. Unfortunately, Schedule S does not have a means to reflect this sort of system

architecture for spare satellites. Thus, for purposes of this application, SpaceX hereby identifies

the location of its spare satellites as sharing the location of the active satellite in each plane with

the minimum mean anomaly in that plane at the orbit epoch date and/or the location 180º

away. SpaceX will continue to optimize the arrangement of its spare satellites and alert the

Commission should its plans change in the future.
