January 27, 2010 Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12"" Street, S.W. Washington, D.C. 20554 Re:. Request for Special Temporary Authority Clarksburg, Maryland Earth Station KA258 Dear Ms. Dortch: ~ Intelsat North America LLC ("Intelsat") herein requests a grant of Special Temporary Authority ("STA")‘ for 30 days, from March 1, 2010 through March 30, 2010 to use its Clarksburg, Maryland Ku—band earth station —— call sign KA258 —— to provide telemetry, tracking and command ("TT&C") services for the Intelsat 16 satellite at its permanent location of 58.10° W.L. Intelsat intends shortly tofile an application to modify the KA258 license to add » 58.10° W.L. as a point of communication. — Intelsat 16 is expected to be launched on February 11, 2010. After in—orbit testing, Intelsat 16 will be placed at its permanent location of 58.10° W.L.2 The Intelsat 16 TT&C operations will be performed at 58.10° W.L. in the following frequency bands: 13997.5 MHz and 14499.5 MHz in the uplink and 12198.25 MHz.and 12198.75 MHz in the downlink. At 58.10° W.L., Intelsat . will operate the TT&C transmissions in conformance with its coordination agreements for the nominal 58.0° W.L. location, as well as with the FCC‘s rules designed to allow co—frequency operatlons in a two—degree separation environment. Operations in the 14499.5 MHz, 12198.25 MHz and 12198.75 MHz frequencies will be consistent with the antenna‘s licensed parameters. With respect to operations in the 13997.5 MHz frequency, Intelsat is attaching Exhibit A, which contains technical information that demonstrates that the operation of the earth station will be compatible with its electromagnetic environment and will not cause harmful interference into any lawfully ‘ Intelsat has filed its STA request, an FCC Form 159, a $175.00 filing fee and this supporting letter electronically via the Internatmnal Bureau‘s Filing System ("IBFS"). . * See Policy Branch Information; Actions Taken, Report No. SAT-00610 File No. SAT—LOA-2008041600085 (June 5, 2009) (Public Notice).

Ms. Marlene H. Dortch January 27, 2010 Page2 operating terrestrial facility." In the extremely unlikely event that harmful interference should occur due to transmissions to or from its earth station, Intelsat will take all reasonable steps to eliminate the interference. \ The provision of TT&C services to the Intelsat 16 satellite at 58.10° W.L. is critical to ensure the safe station—keeping of the satellite at that location. This, in turn, will regult in additional capacity at the nominal 58.0° W.L. location and thereby promotes the public interest. | Please direct any questions regarding this STA request to the undersigned at _ (202) 944—7848.

Créndall Assistant General Counsel Intelsat Corporation Co: _ Kathyrn Medley * The EIRP levels for transmissions in the 13997.5 MHz frequency will be consistent with the antenna‘s licensed parameters.

Exhibit A Compliance of Operations in the 13.75 — 14.0 GHz Band with FCC Report & Order . (FCCI6—377) ' ~ 1. . Background This exhibit is preserited to demonstrate the extent to which the Intelsat North America LLC earth station KA258 is in compliance with FCC Report & Order 96—377. The potential interference from the earth station to U.S. Navy shipboard radiolocation operations (RADAR) and the NASA space research operations in the 13.75 — 14.0 GHz Band is addressed in this exhibit. The parameters for the earth station are: Table 1. EarthStation Characteristics e Coordinates (NAD83): 39° 13° 06.6" N, 77° 16° 15.3" W e Satellite Location for Earth Station: Intelsat 16 from 48.0° W to45 8° W e Frequency Band: . 13.9975 GHz for uplink .« Polarizations: Circular and Linear e Emissions: — O . | 850KG7D e Modulation: ’ ' Digital e Maximum Aggregate Uplink EIRP: 85.0 dBW for all Carriers e Transmit Antenna Characteristics Antenna Size: . 14.2 meter in Diameter Antenna Type/Model: TIW Gain: 64.7 dBi e _ RF power into Antenna Flange: 20.3 dBW or 21.0 dBW/ MHz _ or —3.0 dBW/4 kHz (Maximum) e Minimum Elevation Angle: — . Clarksburg, MD 35.4° @ 138.4° Az.at 48.0° W > ' — 40.4° @ 151.1° Az. at 58.0° W e Side Lobe Antenna Gain: 32 — 25*log(8)

Because the above uplink spectrum is shared with the federal government, analysis of potential interference between the earth station and both Navy Department and NASA systems is required. Potential interference from the earth station could impact the Navy and/or NASA systems in two areas.. These areas are noted in FCC Order 96—377 and consist of (1) Radiolocation and radio navigation and (2) Data Relay Satellites. Summary of Coordination Issues: 1) Potential Impact to Government Radiolocation (Shipboard Radar) 2) Potential Impact to NASA Data Relay Satellite Systems (TDRSS) 2. = PotentialImpact to Government Radiolocation (Shipboard Radar) Radiolocation operations (RADAR) may' occur anywhere in the 13.4 — 14 GHz frequency band on U.S. Navy ships. The FCC Order 96—377 allocates the top 250 MHz of this 600 MHz band to _. the Fixed Satellite Service (FSS) on a co—primary basis with the radiolocation operations and provides for an interference protection level of —167 dBW/m*"/4 kHz. The closest distance to shoreline from the Clarksburg, MD earth station is approximately 88 km Southeast towards the Atlantic Ocean. The calculation of the power spectral density at thls distance is given below: 1. Clear Sky EIRP: 85.00 dBW 2. Carrier Bandwidth: 850 kHz 3. PD at antenna input: —3.0 dBW/4 kHz 4. Transmit Antenna Gain: 64.7 dBi 5. Antenna Gain Horizon: FCC Reference Pattern 6. Antenna Elevation Angle: 35.4° and 40.4° The proposed earth station will radiate interference towards the ocean according to its off—axis _ side—lobe performance. A conservative analysis, using FCC standard reference pattern, results in off—axis antenna gains of —6.6 dBi towards the Atlantic Ocean. The calculated signal density at the shoreline, assuming free space loss only: PFD free space only Antenna Feed Power density (dBW/4 kHz) + Antenna Off—Axis Gain (dBi) — Spread Loss (dBw—m*). —3.0 dBw/4 kHz + (—6.6 dBi) — 10*10g[4H*(88000m)] ) —119.5 dBW/m"/4 kHz _ However there is an additional path loss of approximately 68.0 dB, which includes absorption loss and earth diffraction loss for the actual path profiles from the:proposed earth station to the _ nearest shoreline. PFD aCtua]. — PFD free space loss only +Add1t10na1 Path LOSSGS (~ 68 0 dB) =~187.5 dBW/m2/4kHz

The resulting PFD, including additional path losses to the closest shoreline location, is —187.5 dBW/m*/4 kHz. This is 20.5 dB below the —167 dBW/m2/4 kHz interference criteria of FCC Order.96—377. Therefore, the interference to the U.S. Navy RADAR from the earth station will be well within the permissible levels per the FCC‘s rules, given the distance and the terrain blockage between the site and the shore. 3. Potential Impact to NASA‘s Data Relay Satellite System (TDRSS) The geographic location of the Clarksburg, MD earth station is outside the 390 km radius coordination contour surrounding NASA‘s White Sands, NM ground station complex. Therefore, the TDRSS space—to—earth link will not be impacted by Intelsat‘s KA258 earth station. The TDRSS space—to—space link in the 13.772 to 13.778 GHz band is assumed to be protected if an earth station produces an EIRP less than 71 dBW/6 MHz in this band. The 14.2 meter earth station that is the subject of this application will not radiate in this band, as the proposed transmissions will be limited to the 13997.5 GHz frequency. Therefore, there will be interference to the TDRSS space—to—space link. . 4. Summary and Conclusions The results of the analysis and calculations performed in this exhibit indicate compatible operation between the Clarksburg, MD earth station and the U.S. Navy radiolocation systems. Simflérly, there will be no interference above permissible FCC levels into NASA‘s TDRSS systems, as the intended operations are outside of the 13772.0 to 13778.0 MHz frequency range.
