1. CONCLUSIONS An interference study considering all existing, proposed and prior coordinated microwave facilities within the coordination contours of the proposed earth station demonstrates that this site will operate satisfactorily with the common carrier microwave environment. Further, there will be no restrictions of its operation due to interference considerations. Frequency Coordination and Interference Analyéis Report 11/16/2007 Page 3 of 11

2. SUMMARY OF RESULTS A number of great circle interference cases were identified during the interference study of the proposed earth station. Each of the cases, which exceeded the interference objective on a line—of—sight basis, was profiled and the propagation losses estimated using NBS TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal levels to acceptable magnitudes in every case. There are no unresolved interference.cases involving this earth station.

Radiation Hazard Report Page 1 of 6 EXHIBIT C | Analysis of Non-lonizing Radiation for a 19.0—Meter Earth Station System _ This report analyzes the non—ionizing radiation levels for a 19.0—meter earth station system. The ~ analysis and calculations performed in this report comply with the methods described in the FCC Office of Engineering and Technology Bulletin, No. 65 first published in 1985 and revised in 1997 in Edition 97—01. The radiation safety limits used in the analysis are in conformance with the FCC R&O 96—326. Bulletin No. 65 and the FCC R&O specifies that there are two separate tiers of exposure limits that are dependant on the situation in which the exposure takes place and/or the status of the individuals who are subject to the exposure. The Maximum Permissible Exposure (MPE) limits for persons in a General Population/Uncontrolled environment are shown in Table 1. The General Population/Uncontrolled MPE is a function of transmit frequency and is for an exposure period of thirty minutes or less. The MPE limits for persons in an Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of transmit frequency and is for an exposure period of six minutes or less. The purpose of the analysis described in this report is to determine the power flux density levels of the earth station in the far—field, near—field, transition region, between the subreflector or feed and main reflector surface, at the main reflector surface, and between the antenna edge and the ground and to compare theselevels to the specified MPEs: Table 1.

Far Field Distance Calculation _ The distance to the beginning of the far field can be determined from the following equation: Distance to the Far Field Region Rg =0.60 D/A ~ _ (1) = 4465.6 m The maximum main beam power density in the far field can be determined from the following equation: ' ' ' ’ On—Axis Power Density in the Far Field S; =GP/(4rR;") (2) = 6.568 W/m* = 0.657 mW/icm* 2. Near Field Calculation Power flux density is considered to be at a maximum value throughout the entire length of the defined Near Field region. The region is contained within a cylindrical volume having the same diameter as the antenna. Past the boundary of the Near Field region, the power density from the antenna decreases linearly with respect to increasing distance. The distance to the end of the Near Field can be determined from the following equation: Extent of the Near Field Ry = D‘/ (42) (3) | = 1860.7 m The maximum power density in the Near Field can be determined from the following equation: Near Field Power Density Sr = 16.0 1 P / (z.D) (4) — - =15.334 W/im* — = 1.533 mW/icm* 3. Transition Region Calculation The Transition region is located between the Near and Far Field regions. The power density begins to decrease linearly with increasing distance in the Transition region. While the power density decreases inversely with distance in the Transition region, the power density decreases inversely with the square of the distance in the Far. Field region. The maximum power density in the Transition region will not exceed that calculated for the Near Field region. The power density calculated in Section 1 is the highest power density the antenna can produce in any of the regions away from the antenna.

Region between the Main Reflector and the Subreflector Transmissions from the feed assembly are directed toward the subreflector surface, and are reflected back toward the main reflector. The most common feed assemblies are waveguide flanges, horns or subreflectors. The energy between the subreflector and the reflector surfaces can be calculated by determining the power density at the subreflector surface. ~This can be: determined from the following equation: Power Density at the Subreflector . Ssr = 4000 P / Ag, (6) - = 233.860 mW/cm* 5. Main Reflector Region The power density in the main reflector is determined in the same manner as the power density at the subreflector. The area is now the area of the main reflector aperture and can be determined from the following equation:‘ Power Density at the Main Reflector Surface Ssurface Z4 P / Asurface (7) = 28.569 W/m* = 2.857 mW/icm* 6. Regioh between the Main Reflector and the Ground Assuming uniform illumination of the reflector surface, the power density between the antenna and the ground can be determined from the following equation: Power Density between Reflector and Ground Sg =P / Asurtace (8) . = 7.142 W/im* = 0.714 mW/cm* .

The applicant proposes to comply with the MPE limits by one or more of the following methods. | Means of Compliance Uncontrolled Areas This antenna will be located in a fenced area. The fenced are will be sufficient to prohibit the general public from having access the areas that exceed the MPE limits Since one diameter removed from the main beam of the antenna or % diameter removed from the edge of the antenna the RF levels are reduced by a factor of 100 or 20 dB. None of the areas exceeding the MPE levels will be accessible by the general public. Radiation hazard signs will be posted while this earth station is in operation.

Means of Compliance Controlled Areas The earth station‘s operational personnel will not have access to the areas that exceed the MPE levels while the earth station is in operation. The transmitters will be turned off during antenna maintenance.

EXHIBIT D WAIVER REQUEST INTELSAT NORTH AMERICA LLC RASCom—1 LEOP STA REQUEST EARTH STATION KA275

Exhibit D PETITION FOR WAIVER OF SECTIONS 25.137 AND 25.114 Pursuant to Section 25.137 of the Federal Communications Commission‘s ("Commission" or "FCC") rules, earth station applicants "requesting authority to operate with a non—U.S. licensed space station to serve the United States" mustdemonstrate that effective competitive opportunities exist and must prov1de the same technical information required by Section 25.114 for U.S.—licensed space stations.‘ Intelsat herein seeks authonty to provide launch and early orbit phase ("LEOP") services —— not commercial services —— to the United States, and thus believes that Section 25.137 does not apply. To the extent the Commission determines, however, that Intelsat‘s request for authority to provide LEOP services on a special temporary basis is a request to serve the United States with a non U.S.—licensed satellite,Intelsat respectfully requests a waiver of Sections 25.137 and 25 114 of the Commission‘s rules." The Commission may grant a waiver for good cause shown." The Commission typically grants a WaIVCI' where the particular facts make strict compliance inconsistent with the public interest." 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." Waiver is therefore appropriate if special circumstances warrant a deviation from the general rule, and such a deviation will serve the public interest. In this case, good cause exists for a waiver of both Section 25.137 and Section 25.114. With respect to Section 25.114, Intelsat seeks authority only to provide LEOP services for the RASCom—1 satellite. Intelsat has already provided with its STA request all the technical information relating to the LEOP services that Intelsat will be performing. The information sought by Section 25.114 is not relevant to LEOP services. Moreover, Intelsat does not have — and would not easily be able to obtain —— such information because Intelsat is not the operator of the RASCom—1 satellite, nor is Intelsat in contractual privity with that operator. Rather, Intelsat has a contract with Telespazio, which was hired by Thales, the manufacturer of the RASCom-l satellite, to conduct LEOP services for the satellite. The information that Intelsat is not including is not required to determine potential harmful interference. The Schedule S information for this satellite would pertain to the operation of the RASCom—1 satellite at its final orbital location. However, the present application for LEOP services involves communications prior to the satellite attaining its final location in the geostationary orbit. In other words, during the LEOP mission, the earth station will not be \ 47 C.F.R. § 25.137 (emphasis added). 47 C.F.R. §§ 25.137 and 25.114. 3 47 C.F.R. § 1.3. | * NE. Cellular Tel. Co. v. FCC, 897 F.24 1164, 1166(D.C. Cit. 1990) ("Northeast Cellular®). ° WAIT Radio v. FCC, 418 F.2d 1153, 1159 (D.C. Cir. 1969); Northeast Cellular, 897 F.2d at 1166.

communicating with a satellite located in the geostationary orbit. Rather, it will be transmitting to a satellite traveling on its "transfer orbit" or "LEOP path", which starts immediately following its separation from a launch vehicle, and ends when the satellite reaches its geostationary orbital location. Moreover, as with any STA, Intelsat will perform the LEOP services on a non— interference basis. Because it is not relevant to the service for which Intelsat seeks authorization, and because obtaining the information would be a hardship, Intelsat seeks a waiver of all the information required by Section 25.114. As noted above, Intelsat has provided the required technical information that is relevant to the LEOP services for which Intelsat seeks authorization. Good cause also exists to waive Section 25.137. Section 25.137 is designed to ensure that "U.S.—licensed satellite systems have effective competitive opportunities to provide analogous services" in other countries." Here, there is no service being provided by the satellite; it is simply being placed in its orbital location after separating from the launch vehicle. Thus, the purpose of the information required by Section 25.137 is not implicated here. For example, Section 25.137(d) requires earth station applicants requesting authority to operate with a non— U.S.—licensed space station that is not in orbit and operating to post a bond.‘ The underlying purpose in having to post a bond—i.e., to prevent warehousing of orbital locations by operators seeking to serve the United States—would not be served by requiring Intelsat to post a bond in order to provide approximately 10 days of LEOP services to the RASCom—1 satellite. It is Intelsat‘s understanding that RASCom—1 will operate against ITU filings held by RASCOM, an intergovernmental organization, and will be operated by RASCOMStar, a Mauritius compa.ny.8 It is alsoIntelsat‘s understanding that at 2.85° E.L., RASCom—1 will not serve the United States. Thus, the purposes of Section 25.137—to ensure that U.S. satellite _ operators enjoy "effective competitive opportunities" to serve foreign markets and to prevent — warehousing of orbital locations serving the United States—will not be undermined by grant of this waiver request. Finally, Intelsat notes that it expects to operate with the RASCom—1 satellite using its U.S. earth station for a period of approximately 10 days. Requiring Intelsat to obtain copious technical and legal information from an unrelated party, where there is no risk of harmful interference and the operations will cease after approximately 10 days, would pose undue hardship without servingunderlying policy objectives. Given these particular facts, the waiver — sought herein is plainly appropriate. 647 C.F.R. § 25.137(a). " See 47 C.FR. § 25.137(d)(4). 8 Mauritius is a WTO—member country.
