Re:    Request for Special Temporary Authority for Intelsat 20,
       File No. SAT-LOA-20111024-00208, Call Sign S2847

Dear Ms. Dortch:

Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary
Authority (“STA”)1 for Intelsat 20 (Call Sign S2847) for 30 days—from July
27, 2012 through August 25, 2012—to (1) seek a waiver of the U.S. Table of
Frequency Allocations to permit launch and early orbit phase (“LEOP”)
operations using downlink frequencies in the 12700-12750 MHz band in
Region 2;2 (2) conduct in-orbit testing (“IOT”) at 63.15º E.L.; and (3) drift the
satellite to its permanent location of 68.5° E.L.3 Intelsat 20 currently is
scheduled to be launched on July 27, 2012.

LEOP. Intelsat seeks a waiver of the U.S. Table of Frequency Allocations to
permit Intelsat 20 LEOP telemetry downlink Fixed-Satellite Service (“FSS”)
transmissions in the 12700-12750 MHz band in Region 2.4 In the U.S. Table
of Frequency Allocations, the 12700-12750 MHz band is allocated to Fixed

The Intelsat 20 satellite LEOP transmissions will be 500 kHz transmissions
centered at the 12746.5 MHz, 12747.0 MHz, 12748.0 MHz, and 12748.5 MHz
frequencies.

Intelsat will coordinate LEOP operations for Intelsat 20 with all operators of
satellites that use the same frequency bands and are in the LEOP path. As
such, there will be no risk of interference with respect to lawfully operating,
co-frequency satellites. Nevertheless, all operators of satellites in that path will
be provided with an emergency phone number where the licensee can be
reached in the event that harmful interference occurs. The 24x7 contact
information for the Intelsat 20 LEOP mission is as follows:

     (310) 525-5900 – West Coast Operations Center (back-up)
Request to speak with Bob Main.

The Commission may grant a waiver for good cause shown.6 The Commission
typically grants a waiver where the particular facts make strict compliance
inconsistent with the public interest.7 In granting a waiver, the Commission
may take into account considerations of hardship, equity, or more effective
implementation of overall policy on an individual basis.8 Waiver therefore is
appropriate where special circumstances warrant a deviation from the general
rule, and such a deviation will serve the public interest.

Good cause exists for a waiver because Intelsat’s downlink use of the 12700-
12750 MHz band for LEOP in Region 2 will not cause harmful interference to
any terrestrial stations or satellites.9 Terrestrial stations within the United

States will not be subjected to harmful interference from the telemetry
transmissions of Intelsat 20 because the satellite’s telemetry carriers are
compliant with the International Telecommunication Union (“ITU”) space-to-
Earth power flux density (“PFD”) limits over the Earth. Specifically, in order
to ensure protection of terrestrial communication links from space station
transmissions, Article 21.16 of the ITU Radio Regulations imposes PFD limits
on satellite transmissions in the space-to-Earth direction.10 In the pending
Intelsat 20 application, Intelsat calculated the PFD level of its telemetry
carriers on the Earth.11 These calculations show that the Intelsat 20 telemetry
transmissions will be compliant with the PFD limits specified in Art. 21.16 of
the ITU Radio Regulations.12 Accordingly, terrestrial stations operating in ITU
Region 2 will not be subjected to harmful levels of interference from Intelsat
20’s telemetry transmission. Moreover, space stations operating in the 12700-
12750 MHz frequency band will not be impacted because Intelsat will
coordinate the telemetry of Intelsat 20 with any affected satellite operators that
are in the LEOP path.

IOT. Intelsat seeks to conduct in-orbit testing of Intelsat 20 (Call Sign S2847)
at 63.15º E.L. in the bands 3700-4200 MHz (downlink), 5925-6675 MHz
(uplink), 10950-11200 MHz (downlink), 11450-11700 MHz (downlink),
12500-12750 MHz (downlink),13750-14500 MHz (uplink), 29500-30000
MHz (uplink) and 19700-20200 MHz (downlink). To Intelsat’s knowledge,
the only co-frequency satellites within plus/minus six degrees of 63.15º E.L.
are Intelsat 904 at 60.0º E.L., Intelsat 902 at 62.0º E.L., Intelsat 906 at 64.15º
E.L., Intelsat 17 at 66.0º E.L., Intelsat 7 at 68.65 E.L., Intelsat 10 at 68.5º E.L.,
and Inmarsat 3-F1 at 64.5°E.L. Intelsat will coordinate with Inmarsat, the
operator of Inmarsat 3-F1, regarding the Intelsat 20 IOT. With regard to the
remaining spacecraft, Intelsat will internally coordinate the proposed testing

will not cause interference to other licensed operations, the Commission
generally authorizes it if it is otherwise in the public interest.”).

         ITU Radio Regulations, Art. 21.16 (2008). For ITU Region 2, PFD
limits are specified only for non-geostationary satellites operating in the 11.7 –
12.7 GHz band. However, these limits may also be applied to geostationary
satellites, since the PFD limit is intended to protect terrestrial stations from
space station transmissions irrespective of whether the radiating space station
is geostationary or non-geostationary. Actually, when converted to the same
reference bandwidth, these limits are identical to those applicable to
geostationary FSS space stations in Region 3.
11
         See Intelsat 20 Application, Engineering Statement at Exhibit 11.
12
         It is noted that calculations in the Intelsat 20 application addressing the
PFD produced on the Earth by the telemetry transmissions show that there is
enough margin for the PFD to be met even when during LEOP the satellite is
at a height lower than that corresponding to the geostationary orbit.

with the operations of these satellites. In the unlikely event that harmful
interference occurs, Intelsat will take all necessary steps to eliminate the
interference.

Intelsat is aware that FSS operations are not authorized in the 12500-12750
MHz band in Region 2. In-orbit testing of Intelsat 20 will be conducted by
earth stations located outside the United States and will not affect satellite or
terrestrial operations in the 12500-12750 MHz band in Region 2.

Intelsat has assessed and limited the probability of the space station becoming
a source of debris as a result of collision with large debris or other operational
space stations during in-orbit testing at 63.15º E.L. Intelsat 20 will not be
located at the same orbital location as another satellite or at an orbital location
that has an overlapping station-keeping volume with another satellite. Further,
Intelsat is not aware of any other FCC licensed system, or any other system
applied for and under consideration by the FCC, having an overlapping station-
keeping volume with Intelsat 20. Finally, Intelsat is not aware of any system
with an overlapping station-keeping volume with Intelsat 20 that is the subject
of an ITU filing and that is either in orbit or progressing towards launch.

Drift. During the drift from 63.15º E.L. to 68.5° E.L., Intelsat will utilize only
the satellite’s TT&C frequencies and will follow industry practices for
coordinating TT&C transmissions during the relocation process. The specific
TT&C frequencies are as follows:

Uplink:

13750.5 (V)
14498.0 (V)
13750.5 (LHCP)
14498.5 (LHCP)

Downlink:

12746.5 (V)
12747.0 (V)
12748.0 (V)
12748.5 (V)
12746.5 (LHCP)
12747.0 (LHCP)
12748.0 (LHCP)
12748.5 (LHCP)

Grant of this STA request and waiver of the U.S. Table of Frequency
Allocations set forth in Section 2.106 of the FCC’s rules will facilitate the safe
launch of the Intelsat 20 satellite. The in-orbit testing of Intelsat 20 at 63.15º
E.L. is a critical step in ensuring that the satellite will be fully operational at
68.5º E.L. The subsequent drift of the satellite to 68.5° E.L. will ensure
continuity of service to customers, and thereby promotes the public interest.

For the reasons set forth herein, Intelsat respectfully requests that the
Commission grant this request.

Sincerely,

/s/ Susan H. Crandall
