         Audacy herein refers to its proposed aggregate network of space- and Earth-based infrastructure as the
“Relay Network;” individual satellites as “Relays” or “Satellite Relays;” complementary ground stations as
“Gateways;” and spacecraft using the Network’s communication services as “Users” as further described in the legal
narrative accompanying Audacy’s application. See Audacy Corporation Application for Authority to Launch and
Operate a Non-Geostationary Medium Earth Orbit Satellite System in the Fixed- and Inter-Satellite Services,
Application, IBFS File No. SAT-LOA-20161115-00117 (filed Nov. 16, 2016) (“Audacy Narrative Exhibit”).


I.     INTRODUCTION AND SUMMARY

       Audacy proposes a space-based data relay constellation that will provide operators with

always-on, seamless access to their NGSO spacecraft. End users of the Relay Network include

operators of Earth observation satellites requiring real-time access to photographic and video

data, launch providers needing continuous telemetry from onboard sensors, and operators of

large Low Earth Orbit (“LEO”) constellations requiring continuous command and control of

every satellite simultaneously, wherever they are in their orbit.

       As further described in the Audacy Narrative Exhibit, Audacy’s Relay Network provides

significant public interest benefits, including facilitating commercial access to 24/7 spacecraft

communications and enabling new technologies such as real-time telerobotics and satellite

servicing.4 In addition, Audacy’s Relay Network will dramatically simplify and streamline the

process for coordinating communications between satellites and terrestrial gateway facilities,

which has become increasingly complex and impossible in certain situations due to conflicts

between commercial and scientific missions in already heavily burdened spectrum.

       The Relay Network’s proposed use of V-band frequencies for its feeder link service

triggered participation in the instant processing round. Audacy’s use of such frequencies is

discrete and can be successfully coordinated and introduced without affecting alternative existing

and planned uses of spectrum.


II.    AUDACY’S DISCRETE V-BAND FEEDER LINK SERVICE IS COMPATIBLE
       WITH GSO AND NGSO SYSTEMS


       The comments reflect consensus among interested parties that, with appropriate

conditions and planning, geostationary (“GSO”) and NGSO systems can successfully share the

                                                 2


V-band. Audacy agrees and addresses certain recommendations for license conditions intended

to prevent unacceptable harmful interference from NGSO networks made by interested parties

below.

         A.        Audacy Concurs with Reasonable Equivalent Power Flux Density Limits

         Certain commenters representing GSO interests express concern about interference

resulting from NGSO systems creating single-entry or aggregated incidence of unacceptable

equivalent power-flux density (“EPFD”).5 To address these concerns, the GSO operators,

including ViaSat, Hughes, and SES, urge the Commission to condition V-band license grants

with EPFD limits.

         ViaSat explains that Article 22.2 of the ITU Radio Regulations already applies to NGSOs

in the V-band and requires such systems not to cause unacceptable interference to GSO systems.6

ViaSat elaborates that appropriate single-entry and aggregate EPFD limits, in both uplink and

downlink directions, could be effective means to protect GSOs.7 Hughes similarly requests

adoption of interim or default EPFD limits comparable to the limits specified in Article 22 of the

ITU Radio Regulations.8 SES argues for NGSO licenses to “incorporate single entry and

aggregate EPFD compliance requirements and be subject to modification as necessary to keep

aggregate interference levels from causing harm to future V-band GSO systems.”9

       Audacy appreciates the need to maintain the utility of the V-band by protecting GSO

networks from EPFD-related interference and anticipates a license condition limiting V-band

        See, e.g., ViaSat Comments at 6-7, recommending single entry and aggregate EPFD limits for uplink and
downlink operations; SES Comments at 4, similarly recommending single entry and aggregate EPFD limits; Hughes
Comments at 2, endorsing ITU Article 22 limits for EPFD and a “realistic and practicable mechanism to ensure that
aggregate EPFD limits are met by all licensed Q/V-band NGSO systems.”

EPFD. Audacy has already provided the Commission with materials showing full compliance

with existing Article 22 limits for K-band feeder link services10 and, although Article 22 does not

currently list V-band EPFD limits, Audacy is confident that the Relay Network will meet EPFD

limits comparable to those in K-band,11 if and when such limits are adopted by the Commission.

       Audacy also reemphasizes that its Relay Network will use FSS spectrum for feeder link

service only, delivering aggregated traffic using carefully shaped, narrow spot beams to three

planned gateway earth stations that will employ large, highly efficient antennas. Accordingly,

with the exception of the area in immediate proximity to an Audacy gateway (in this hemisphere

Audacy presently plans only a single gateway at a site in California), the Relay Network will not

contribute to an increase in single-entry or aggregate EPFD. Moreover, given that the Relay

Network will communicate exclusively with large (>6.0 meter), highly efficient/high-gain

gateway antennas, even under an Audacy spot beam, EPFD levels will likely fall below the

levels proposed by other NGSO systems in the instant proceeding.

        B.       Audacy Can Avoid In-Line Interference Events without Band Segmentation

        SES argues that in-line interference events can be avoided through coordination, but that

band segmentation may be needed as “a last resort.”12 Audacy respectfully disagrees that band

segmentation may be needed as a last resort to avoid in-line interference with its Relay Network.

        Audacy Relays are interconnected by way of robust inter-satellite links.13 In the event of

an in-line interference event that cannot be coordinated, the affected Relay will preemptively

offload its customer traffic to one of the two other operational Relays and the relevant paired

gateway earth stations. Hand-off between Relays will be seamless and undetectable by Audacy

end users and provides a reliable interference protection mechanism that facilitates full use of the

proposed FSS frequencies for Audacy feeder links.14 The orbital geometry of Audacy Relay

satellite orbits and planned earth station locations is designed to preclude the possibility of

multiple simultaneous in-line interference events with equatorial NGSO or GSO satellites such

as those operated by SES and its affiliate O3b.

         Given this proven and reliable capability, in-line interference can be effectively avoided

and the Commission need not impose additional conditions related to the mitigation of such

interference.

         C.      Audacy Supports Reasonable Additional License Conditions to Ensure the
                 Utility of V-Band Spectrum and Compliance with FCC Rules

         SES asks the Commission to apply certain conditions to ensure that planned NGSO

operations will be consistent with Commission policies and rules and not create unacceptable

harmful interference to future GSO satellite operations in the V-band. Audacy agrees with the

need to protect GSO spacecraft and supports certain additional license conditions proposed by

SES.

         Specifically, SES requests, and Audacy supports, the following:

        Operations must comport with the legal and technical specifications set forth by the
         applicant absent a waiver request.

        Operations must comply with all coordination agreements.



14
         Audacy will continually use state-of-the-art satellite modeling and orbit propagation tools to predict
potential interference events with FSS networks well before they occur so that coordination and mitigation
techniques can be employed.


                                                      5


          Operators must maintain and make available to the North American Defense Command
           ephemeris data for each satellite.

          Finalize a methodology by which the system will share spectrum with other NGSO
           constellations issued prior to or as part of this processing round.15

III.       FAVORABLE TREATMENT OF AUDACY’S LICENSE SHOULD NOT BE
           DELAYED PENDING THE OUTCOME OF CONTEMPORANEOUS
           RULEMAKINGS

           Several commenters urge the Commission to expand the ongoing NGSO K-band

Rulemaking to the V-band and retroactively apply rules adopted in an expanded rulemaking

indiscriminately to all applicants in the instant processing round.16 The NGSO-K-band

rulemaking, however, was initiated for the purpose of developing service link rules for networks

deploying hundreds (or thousands) of satellites intended to deliver broadband service to small,

inefficient earth stations terminals deployed en masse.17

           Given the meaningful distinctions between Audacy’s Relay Network, which involves the

use of FSS spectrum only for narrowly tailored feeder links between three discrete spacecraft

paired with three gateway earth stations, and other NGSO systems involved in the instant

proceeding which employ FSS spectrum for widespread service links between large fleets of

LEO spacecraft and potentially vast numbers of individual and/or enterprise terminals on the

ground, a blanket application of service rules intended to regulate the latter on the former may

prove untenable depending on the final rule.

IV.    AUDACY CLARIFIES ITS PROPOSED USE OF V-BAND SPECTRUM

       SpaceX requests clarification on certain aspects of Audacy’s proposed use of V-band

spectrum. Specifically, SpaceX requests clarification on Audacy’s use of “off-nominal beams,”

including whether such links will comply with likely EPFD limits.18

       Audacy clarifies that it has applied for 4 GHz and 4.5 GHz of V-band FSS spectrum for

its feeder uplink and downlink operations respectively.19 SpaceX is correct that Audacy has

applied for “500 MHz of spectrum in each direction for TT&C links in off-nominal, emergency

situations,” however this proposed use is in the K-band,20 not V-band as suggested by SpaceX.

Audacy has already provided the Commission with showings of full compliance with both FCC

and ITU Article 21/22 PFD and EPFD limits in these K-band frequencies by both space and

earth stations,21 and looks forward to coordinating with individual operators to ensure that there

is no possibility of harmful interference in the event that Audacy has recourse to use these bands.
