In the attached Engineering Statement, Intelsat provides an interference analysis of the effect of Intelsat 706 (call sign S2401) transmissions from the 72.1° E.L. orbital location on adjacent satellites. As set forth in Sections 25.114(d)(7) and 25.140(b)(2) of the Commission’s rules, this analysis demonstrates the compatibility of Intelsat 706 two degrees from any authorized space station.1 1 47 C.F.R. §§ 25.114(d)(7) and 25.140(b)(2).

Engineering Statement Intelsat License LLC (“Intelsat”) (f/k/a Intelsat North America LLC) hereby supplements its pending application SAT-MOD-20100511-00098 pertaining to the proposed operation of Intelsat 706 from 72.1º E.L. Specifically, Intelsat proposes to replace the text in the section titled “Adjacent Satellite Link Analysis” of the Engineering Statement contained in its pending application with that provided herein and to include two new exhibits, 6 and 7. The inclusion of this supplementary information was requested by the Commission in a letter to Intelsat dated December 17, 2010. The new text for the section “Adjacent Satellite Link Analysis” and Exhibits 6 and 7 are provided below: Adjacent Satellite Link Analysis The impact of the proposed Intelsat 706 emissions on the transmissions of a hypothetical adjacent satellite located at 70.1º E.L and 74.1º E.L was analyzed. It was assumed that each of these satellites had the same operating characteristics as the proposed Intelsat 706 spacecraft. In order to minimize the number of calculations to be performed, the following combined beam peak performance characteristics were assumed for the satellites at 70.1º E.L and 74.1º E.L: Beam Beam Peak Beam Peak Peak Beam Beam G/T SFD Range EIRP Name Polarization (dB/K) (dBW/m2) (dBW) Global Circular -7.5 -90.4 to -76.4 33.5 Hemi Circular -3.5 -91.4 to -77.4 38.3 Zone Circular -4.0 -89.9 to -75.9 38.8 C-Spot Circular 2.5 -92.7 to -78.7 40.6 Ku-Spot Linear 4.5 -93.8 to -79.8 54.1 For the satellite located at 70.1º E.L, it was assumed that the adjacent satellites were Intelsat 706, located at 72.1º E.L, and a hypothetical satellite located at 68.65º E.L having the combined coverage beams of IS-10 (currently located at 68.5º E.L) and IS-7 (currently located at 68.65º E.L). For the satellite located at 74.1º E.L, it was assumed that the adjacent satellites were Intelsat 706, located at 72.1º E.L, and a hypothetical satellite Page 1 of 6

having the same operating characteristics as Intelsat 706 located at 76.1º E.L. For the C-band analysis, it was assumed that Intelsat 706 and the hypothetical satellites located at 68.65º E.L and 76.1º E.L operated with a maximum uplink power density of -38.7 dBW/Hz. It was further assumed that at C-band the satellite located at 68.65º E.L. operated with a maximum downlink beam peak EIRP density of -34.1 dBW/Hz while Intelsat 706 and the hypothetical satellite at 76.1º E.L operated with a maximum downlink EIRP density of -34.2 dBW/Hz. For the Ku-band analysis, it was assumed that Intelsat 706 and the hypothetical satellites located at 68.65º E.L and 76.1º E.L operated with a maximum uplink power density of -45 dBW/Hz. It was further assumed that at Ku-band the satellite located at 68.65º E.L operated with a maximum downlink beam peak EIRP density of -18.3 dBW/Hz while Intelsat 706 and the hypothetical satellite at 76.1º E.L operated with a maximum downlink density of -20.4 dBW/Hz. For both C-band and Ku-band, downlink EIRP densities were computed by dividing the peak EIRP by the minimum occupied bandwidth for a full transponder utilization. The analysis considered the impact of Intelsat 706’s digital carriers on a wide band digital carrier of the adjacent satellites located at 70.1º E.L and 74.1º E.L. Wide band carriers typically determine the minimum receiving earth station size and lead to the highest downlink EIRP density for a spacecraft. The impact of Intelsat 706 TV/FM carriers on the transmission of the adjacent satellites at 70.1º E.L and 74.1º E.L was not considered for the reasons articulated in the section above (titled “Link Budgets and Interference Analysis”). The assumptions made in the above section pertaining to Earth station off-axis gain performance, Earth station cross- polarization performance and rain attenuation were also applied in the analysis. The results of the analysis are listed in Exhibits 6 and 7 and show that the proposed operation of Intelsat 706 would not have a significant impact on the operation of a satellite located at either 70.1º E.L and 74.1º W.L. Accordingly, Intelsat 706 transmissions will be limited to those levels contained in Sections 25.212(c) and (d) of the rules, as applicable, unless Page 2 of 6

higher levels are coordinated with affected adjacent satellite operators. In any case, pursuant to the results in Exhibits 6 and 7, at C-band, the uplink power density level of Intelsat 706’s digital carriers will not exceed -38.7 dBW/Hz and the downlink EIRP density of such carriers will not exceed - 34.2 dBW/Hz. Similarly, at Ku-band, the uplink power density level of Intelsat 706’s digital carriers will not exceed -45 dBW/Hz and the downlink EIRP density of such carriers will not exceed -20.4 dBW/Hz.
