Frequency Beam Coverage band C-Band Wide Beam United States including Alaska and Hawaii Ku-Band K1–K57 United States including Alaska and Hawaii Ka-Band A1–A57 United States including Alaska and Hawaii 2.1 Spacecraft Characteristics Galaxy 15R is a three-axis stabilized type spacecraft that has a rectangular outer body structure. Galaxy 15R utilizes two deployable solar array wings and a number of deployable and non-deployable antennas. The Galaxy 15R spacecraft is composed of the following subsystems: 1) Thermal 2) Power 3) Attitude Control 4) Propulsion 5) Telemetry, Command, and Ranging (“TC&R”) 6) Uplink Power Control (“ULPC”) 7) Communications These subsystems maintain the correct position and attitude of the spacecraft, ensure that all internal units are maintained within the required temperature range, and ensure that the spacecraft can be commanded and controlled with a high level of reliability from launch to the end of its useful life. The spacecraft design incorporates redundancy in each of the various subsystems in order to avoid single point failures. The structural design of Galaxy 15R provides mechanical support for all subsystems. The structure supports the communication antennas, solar arrays, and the thrusters. It also provides a stable platform for preserving the alignment of critical elements of the spacecraft. 2.2 Communication Subsystem Galaxy 15R provides active communication channels at C-band, Ku-band, and Ka-band frequencies. The C-band payload employs channels with bandwidths of 36 MHz. The Ku-band payload employs channels having bandwidths of 36 MHz, 72 MHz, and 84 MHz. The Ka-band payload employs channels having bandwidth of 36 MHz, 72 MHz, 96 MHz and 125 MHz. The Galaxy 15R frequency and polarization plan is provided in Schedule S. Page 2 of 15

Galaxy 15R utilizes a combination of wide-beam and multiple spot-beam architecture. A wide beam that covers the United States, including Alaska and Hawaii, operates in C- band. In both Ku-band and Ka band, there are 57 identical spot beams that collectively cover the United States, including Alaska and Hawaii. The coverage contours and performance characteristics for only a single representative Ku-band spot beam and a single representative Ka-band spot beam are provided in Schedule S. The latitude and longitude of each Ku-band and Ka-band spot beam’s maximum gain point on the Earth are provided in Exhibits 1 and 2 in conformance with Section 25.114(c)(4)(vii)(B) of the Commission’s rules. Additionally, in Exhibit 3, Intelsat has included the Schedule S beam designation for all beams. The performance characteristics of all Galaxy 15R beams are provided in Schedule S. The coverage contours of all Galaxy 15R beams, except for those with their -8.0 dB contour extending beyond the edge of the Earth, are provided with Schedule S. Exhibits 4 and 5 provide the beam parameters for the Galaxy 15R uplink and downlink beams, respectively. All C-band, Ku-band, and Ka-band communication subsystems are inter-connected, which allows for any frequency combination for the uplink and downlink connectivity at sub-beam level. Additionally, a beam can have multiple connections to several other beams by splitting the channels into sub-channels of variable sizes. The expected dominant application for Galaxy 15R will be composed of hub and spoke networks whereby one earth station serves as the hub or gateway for a number of other earth stations. The earth stations’ predominant communication links will be with the hub. All Galaxy 15R beams can be used for both gateway and service links.3 2.3 Telemetry, Command and Ranging Subsystem The TC&R subsystem provides the following functions: 1) Acquisition, processing and transmission of spacecraft telemetry data; 2) Reception and retransmission of ground station generated ranging signals; and 3) Reception, processing and distribution of telecommands. The Galaxy 15R command and telemetry subsystem performance is summarized in Exhibit 6 and in Schedule S. The beams used for orbital maneuvers and on-station emergencies as well as the on-station beams have gain contours that vary by less than 8 dB across the surface of the Earth, and accordingly the gain at 8 dB below the peak falls beyond the edge of the Earth. Therefore, pursuant to Section 25.114(c)(4)(vi)(A) of the 3 Use of the band 27500 MHz-28350 MHz by earth stations will be subject to Section 25.136. Page 3 of 15

Commission’s rules, contours for these beams are not required to be provided and the associated GXT files have not been included in Schedule S. 2.4 Uplink Power Control Subsystem Galaxy 15R utilizes one C-band channel, one Ku-band channel, and one Ka-band channel for ULPC, antenna tracking, and ranging. The coverage patterns of the ULPC beams have gain contours that vary by less than 8 dB across the surface of the Earth, and accordingly the gain at 8 dB below the peak falls beyond the edge of the Earth. Therefore, pursuant to Section 25.114(c)(4)(vi)(A) of the Commission’s rules, contours for these beams are not required to be provided and the associated GXT files have not been included in Schedule S. The Galaxy 15R ULPC subsystem performance is summarized in Exhibit 6. 2.5 Satellite Station-Keeping The spacecraft will be maintained within 0.05° of its nominal longitudinal position in the east-west direction. Accordingly, it will comply with Section 25.210(j) of the Commission’s rules. The attitude of the spacecraft will be maintained with accuracy consistent with the achievement of the specified communications performance, after taking into account all error sources (i.e., attitude perturbations, thermal distortions, misalignments, orbital tolerances, and thruster perturbations, etc.). 3 Services Galaxy 15R will be a general purpose communications satellite and has been designed to support various services offered within Intelsat’s satellite system. Depending upon the needs of the users, the transponders on Galaxy 15R can accommodate television, radio, voice, and data communications. Typical communication services include: a) Compressed digital video b) High speed digital data c) Digital single channel per carrier (“SCPC”) data channels 4 Power Flux Density (“PFD”) The power flux density (“PFD”) limits for space stations operating in the 3700–4200 MHz, 10950–11200 MHz, 11450–11700 MHz, 11700–12200 MHz and 18300–18800 MHz are specified in Section 25.208 of the Commission’s rules. Also, Section 25.138(a)(6) of the Commission’s rules specify a PFD limit of -118 dBW/m2/MHz for space stations operating in the 18300–18800 MHz and 19700–20200 MHz bands. The Commission’s rules do not specify a PFD limit in the 17800–18300 MHz or 18800– Page 4 of 15

19300 MHz bands; however, there are PFD limits specified in rule No. 21.16 of the International Telecommunication Union (“ITU”) Radio Regulations. The maximum PFD levels for the Galaxy 15R transmissions were calculated for the bands 3700–4200 MHz, 10850–11700 MHz, 17800–18300 MHz, 18300–18800 MHz, 18800–19300 MHz, and 19700–20200 MHz. The results are provided in Schedule S and show that the downlink power flux density levels of the Galaxy 15R carriers do not exceed the limits specified in Sections 25.208 and 25.138 of the Commission’s rules, nor those in rule No. 21.16 of the ITU Radio Regulations, as applicable. 5 Emission Compliance Section 25.202(e) of the Commission’s rules requires that the carrier frequency of each space station transmitter be maintained within 0.002% of the reference frequency. Galaxy 15R is designed to be compliant with the provisions of this rule. Intelsat will comply with the provisions of Section 25.202(f) of the Commission’s rules with regard to Galaxy 15R emissions. 6 Orbital Location Intelsat requests that it be assigned the 133.0° W.L. orbital location for Galaxy 15R. The 133.0° W.L. location satisfies Galaxy 15R’s requirements for optimizing coverage, elevation angles, and service availability. Additionally, the location also ensures that the maximum operational, economic, and public interest benefits will be derived. 7 ITU Filings Galaxy 15R’s operations in the 3700–4200 MHz, 5925–6425 MHz bands have been coordinated under the Administration of the United States’ ITU filing USASAT-22A, USASAT-35Y and USASAT-50B. For the operation of Galaxy 15R in the frequencies 13750–14500 MHz, 10950–11200 MHz, 11450–12200 MHz, 27500–29100 MHz, 29250–30000 MHz, 17800–19300 MHz, and 19700–20200 MHz, Intelsat will be submitting as part of this application the corresponding Appendix 4 information for the new satellite network to be forwarded by the FCC to the ITU.

8 Coordination Statement and Certifications The downlink EIRP density of Galaxy 15R’s transmissions in the conventional C-band will not exceed 3 dBW/4kHz for digital transmissions or 8 dBW/4kHz for analog transmissions, and associated uplink transmissions will not exceed applicable EIRP density envelopes in Sections 25.218 or 25.221(a)(1) unless the non-routine uplink and/or downlink operation is coordinated with operators of authorized co-frequency space stations at assigned locations within six degrees of Galaxy 15R at 133.0° W.L. The downlink EIRP density of Galaxy 15R’s transmissions in the conventional and extended Ku-band will not exceed 14 dBW/4kHz for digital transmissions or 17 dBW/4kHz for analog transmissions, and associated uplink transmissions will not exceed applicable EIRP density envelopes in Sections 25.218, 25.222(a)(1), 25.226(a)(1), or 25.227(a)(1) unless the non-routine uplink and/or downlink operation is coordinated with operators of authorized co-frequency space stations at assigned locations within six degrees of Galaxy 15R at 133.0° W.L. PFD at the Earth’s surface produced by emissions from a space station in the conventional Ka-band, 18300–18000 MHz and 19700–20200 MHz for all conditions, including clear sky, and for all methods of modulation shall not exceed a level of −118 dBW/m2/MHz, and in addition will not exceed the limits specified in § 25.208(d). The associated uplink transmissions will not exceed applicable EIRP density envelopes in Sections 25.138 unless the non-routine operation is coordinated with operators of authorized co-frequency space stations at assigned locations within six degrees of Galaxy 15R at 133.0° W.L. 9 Orbital Debris Mitigation Plan Intelsat is proactive in ensuring safe operation and disposal of this and all spacecraft under its control. The four elements of debris mitigation are addressed below. 9.1 Spacecraft Hardware Design The spacecraft is designed such that no debris will be released during normal operations. Intelsat has assessed the probability of collision with meteoroids and other small debris (<1 cm diameter) and has taken the following steps to limit the effects of such collisions: (1) critical spacecraft components are located inside the protective body of the spacecraft and properly shielded; and (2) all spacecraft subsystems have redundant components to ensure no single-point failures. The spacecraft does not use any subsystems for end-of- life disposal that are not used for normal operations. 9.2 Minimizing Accidental Explosions Intelsat has assessed the probability of accidental explosions during and after completion of mission operations. The spacecraft is designed in a manner to minimize the potential for such explosions. Propellant tanks and thrusters are isolated using redundant valves Page 6 of 15

and electrical power systems are shielded in accordance with standard industry practices. At the completion of the mission and upon disposal of the spacecraft, Intelsat will ensure the removal of all stored energy on the spacecraft by depleting all propellant tanks, venting all pressurized systems and by leaving the batteries in a permanent discharge state. 9.3 Safe Flight Profiles Intelsat has assessed and limited the probability of the space station becoming a source of debris as a result of collisions with large debris or other operational space stations. With the potential exception of co-location during a traffic transition period, Galaxy 15R 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. Galaxy 15R will replace Galaxy 15 at 133.0° W.L. These satellites may be nominally collocated during transfer of traffic and Intelsat will ensure that sufficient spatial separation is achieved between these two satellites through the use of orbit eccentricity and inclination offsets and thus minimize the risk of collision. 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 Galaxy 15R. Intelsat is also not aware of any system with an overlapping station-keeping volume with Galaxy 15R that is the subject of an ITU filing and that is either in orbit or progressing towards launch. 9.4 Post Mission Disposal At the end of the mission, Intelsat will dispose of the spacecraft by moving it to an altitude of at least 280 kilometers above the geostationary arc. Intelsat has reserved 2.0 kilograms of xenon for that purpose. In calculating the disposal orbit, Intelsat has used simplifying assumptions as permitted under the Commission’s Orbital Debris Report and Order.4 The effective area to mass ratio (Cr*A/M) of the Galaxy 15R spacecraft is 0.045 m2/kg, resulting in a minimum perigee disposal altitude under the Inter-Agency Space Debris Coordination Committee formula of 280 kilometers above the geostationary arc. Accordingly, the Galaxy 15R planned disposal orbit complies with the FCC’s rules. The reserved fuel figure was determined by the spacecraft manufacturer and provided for in the propellant budget. This figure was calculated taking into account the expected mass of the satellite at the end of life and the required delta-velocity to achieve the desired orbit. The fuel gauging uncertainty has been taken into account in these calculations. 4 Mitigation of Orbital Debris, Second Report and Order, 19 FCC Rcd 11567 (2004). Page 7 of 15

10 TC&R Control Earth Stations Intelsat will conduct TC&R operations through one or more of the following earth stations: Napa, CA, Hagerstown, MD, and Ellenwood, GA. Additionally, Intelsat is capable of remotely controlling Galaxy 15R from its facilities in McLean, VA or Long Beach, CA. Page 8 of 15
