Attachment B ‐ Engineering Statement 1. Scope This Attachment contains additional information required by Section 25.114 and other sections of the Part 25 rules that cannot be entered into the Schedule S online submission system. 2. General Description (Section 25.114(d)(1)) The Eutelsat 172B satellite will operate at the 172° E.L. orbital location and is intended as a replacement for the Eutelsat 172A satellite that currently operates at 172° E.L. The Eutelsat 172B satellite will provide a range of FSS services over the Pacific Ocean and to various countries within and bordering the Pacific Ocean using the C‐ and Ku‐band frequencies for service links and Ka‐band for gateway links. The satellite employs 14 C‐band transponders and 40 Ku‐band transponders using both linear polarizations thereby providing dual frequency re‐use. The satellite has one C‐band beam which provides coverage of the West coast of the United States and Canada and the Asia‐Pacific region, including Australia, Japan, Indonesia, the Philippines and a portion of China. The satellite has five (5) regional Ku beams covering: North Pacific, South Pacific, South‐West Pacific, South‐East Pacific, and North‐East Asia. In addition to the beams described, which effectively reproduce the capabilities of the Eutelsat 172A satellite, this satellite introduces a High‐Throughput Satellite (HTS) Ku‐band payload with eleven (11) spot beams covering the North Pacific. Also, unique to the Eutelsat 172B satellite are several Ka‐band gateway beams, including one within U.S. territory at Hawaii. The Ka‐band gateway beams are intended mostly to serve the new HTS Ku‐band beams but are also able to connect with any of the regional Ku‐ band beams. 3. Spacecraft Overview Eutelsat 172B was manufactured and supplied by Airbus Defense and Space based on the Airbus Eurostar 3000e bus platform. The satellite is 3‐axis stabilized and uses electrical propulsion for initial orbit raising, on‐station control, and end‐of‐life deorbit. The Eutelsat 172B satellite is a triple mission satellite with three distinct payloads:

 A C‐band payload delivering increased power and broader coverage to enhance the service provided today to customers via Eutelsat 172A and tap into new growth markets in the Asia‐ Pacific region;  A traditional Ku‐band payload which will double capacity at 172° East and connect five improved service areas: North Pacific, North East Asia, South East Pacific, South West Pacific and South Pacific;  An innovative HTS Ku‐band payload designed for in‐flight broadband, with multiple user spots optimized to serve densely used Asian and trans‐Pacific flight paths. The spacecraft can operate in C‐band, Ku‐band, and Ka‐band frequencies listed in the table below: C‐band Uplink 5925 – 6425 MHz Downlink 3700 – 4200 MHz Ku‐band Uplink 13.0 ‐13.25 GHz 13.75 – 14.0 GHz 14.0 – 14.5 GHz Downlink 10.95 – 11.20 GHz 11.2 – 11.45 GHz 11.45 – 11.7 GHz 12.2 – 12.75 GHz Ka‐band Uplink 27.5 – 29.15 GHz Downlink 18.4 – 19.2 GHz1 The spacecraft provides the following coverage. For the scope of this filing, the only pertinent coverage area is Oahu, HI.

Telemetry, Tracking and Control (TT&C) The Eutelsat 172B TT&C sub‐system provides for communications during pre‐launch, transfer orbit and on‐station operations, as well as during spacecraft emergencies. Ku‐band telecommand transmissions are received by the spacecraft and Ku‐band telemetry communications are transmitted by the spacecraft through a near omni‐directional antenna during both transfer orbit and emergency operations. TT&C communication channels have been selected at the edge of the assigned Ku‐band per Section 25.202(g). TT&C operations will be conducted from Australia, Eutelsat does not seek Commission authorization for TT&C transmissions.

Frequency Tolerance The frequency tolerance requirements of Section 25.202(e) that the carrier frequency of each space station transmitter be maintained within 0.002% of the reference frequency will be met. 7. Out of Band Emissions The out‐of‐band emission limits of Section 25.202(f)(1), (2) and (3) will be met. 8. Frequency Reuse Eutelsat 172B employs full frequency reuse on the Ka‐band gateway uplink by employing dual orthogonal circular polarization. The satellite employs a single polarization on the gateway downlink.

9. Cessation of Emissions All downlink transmissions can be turned on and off by ground telecommand, thereby causing cessation of emissions from the satellite, as required by Section 25.207 of the FCC’s rules. 10. ITU Filings The Eutelsat 172B Ka‐band gateway links will operate under ITU filing F‐SAT‐N‐172E filed via the French administration. This network has been notified to the ITU. 11. PFD Analysis The Eutelsat 172B satellite is compliant with Section 25.208 PFD requirements in all transmitting bands as demonstrated in the Schedule S submission. 12. Link Budgets Link analysis for Eutelsat 172B was conducted for a number of representative carriers in the HTS services. For each of these links it was assumed that the nearest satellite to Eutelsat 172B was a hypothetical satellite operating at 170 E.L. and a hypothetical satellite operating at 174 E.L. Each of these hypothetical satellites were assumed to have the same operating parameters as Eutelsat 172B. The following assumptions were used in the link budget analysis:  The link budgets are for clear sky operation.  The clear sky link margins were chosen to provide sufficient link availability for the service(s).  All transmitting and receiving earth stations have a cross‐polarization isolation value of at least 27 dB within their main beam lobe. The results of the analysis are shown in Exhibit 1. 13. Interference Analysis In this section, the information specified in Section 25.140 (a) is presented (as required by Section 25.114(d)(7)). Eutelsat 172B downlink transmissions in the conventional Ka‐band will not generate power flux‐density at the Earth's surface in excess of the levels provided in Section 25.140 (a)(3)(iii), and that associated uplink operation will not exceed applicable EIRP density envelopes in Section 25.138(a) 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 Eutelsat 172B at 172.0° E.L. 13.1 Adjacent Satellite Link Analysis (Section 25.140(a)(3)(v)) The Eutelsat 172B satellite will operate in bands addressed by Section 25.140(a)(3)(v). Since there are no commercial satellites operating within 2° of Eutelsat 172B, the impact of those operations on hypothetical satellites having the same operating characteristics as Eutelsat 172B located at 170.0° E.L. and 174° E.L. was analyzed. The satellite at 170.0° E.L. was assumed to have two adjacent satellites separated by 2°: Eutelsat 172B at 172° E.L. and a hypothetical satellite having the same operating

characteristics as Eutelsat 172B located at 168° E.L. The satellite at 174° E.L. was assumed to have two adjacent satellites separated by 2°: Eutelsat 172B at 172° E.L. and a hypothetical satellite having the same operating characteristics as Eutelsat 172B located at 176° E.L. The link interference analysis demonstrating compatibility of Eutelsat 172B with these hypothetical satellite systems was performed for representative carriers for Ka‐Band gateway links connected with HTS user links. Other assumptions used in the analysis were as follows:  The transmitting and receiving earth station antennas have off‐axis co‐polar gains that are compliant with the limits specified in Section 25.209(a) of the FCC’s rules.  The Adjacent Satellite Interference (ASI) is computed based on EIRP densities.  The uplink RF power density for each adjacent satellite is based on the maximum allowed in that frequency band (the provided analysis shows both cases where the interfering satellites operate at maximum power densities and when the interfering satellites are operating at the same power density as the signal of interest)  The downlink EIRP density for each adjacent satellite is based on the maximum allowed in that frequency band (the provided analysis shows both cases where the interfering satellites operate at maximum EIRP densities and when the interfering satellites are operating at the same EIRP density as the signal of interest). The results of the Ka‐Band gateway link to HTS user link interference analysis are shown in Exhibit 2 (for a hypothetical satellite at 170 E.L.) and Exhibit 3 (for a hypothetical satellite at 174 E.L.) and demonstrate that the operation of Eutelsat 172B will permit the intended services for hypothetical satellites in slots 2° away while maintaining sufficient link margin. 14. Sharing with NGSO FSS in the 28.6 to 29.1 GHz and 18.8 to 19.2 GHz Band Under the FCC’s band plan, the 28.6‐29.1 GHz band is allocated to NGSO FSS on a primary basis and to the GSO FSS on a secondary basis. Stations operating as a secondary service cannot cause harmful inference, nor seek interference protection from, co‐frequency stations of a primary service. Eutelsat 172B’s operations in the United States in this band will be consistent with the obligations of a secondary user. Under the FCC’s band plan, the 18.8‐ 19.3 GHz band is available on a primary basis only to the NGSO FSS. A waiver is needed to allow the E172B satellite to operate in the 18.8 – 19.2 GHz band. Operations with Eutelsat 172B will not cause harmful interference to, nor seek protection from, NGSO operations in this band. The analysis in this section demonstrates compatibility with NGSO FSS operations in these band segments. The O3b constellation consists of 12 satellites in a medium earth orbit with an altitude of 8062 km and an inclination of zero degrees (an equatorial orbit). The satellites use steerable gateway spot beams which are oriented towards the gateways as the satellite traverses its orbit until the angle of arrival at the gateway falls below a minimum. An interference analysis is shown below

that indicates that the Eutelsat 172B and O3b networks can operate without causing harmful interference into each other. To evaluate the impact of interference from Eutelsat 172B into O3b and vice versa, it was necessary to compute the worst case angular separation (the smallest angle between the Eutelsat satellite and any of the satellites of the O3b constellation from the earth station location). A conservative assumption that simplifies that analysis was made that earth stations communicating with O3b and Eutelsat 172B are collocated. For collocated earth stations on Oahu, HI, this analysis produced a minimum angular separation of 10.6 between Eutelsat 172B and any O3b satellite. Other system parameters used in analysis are based on those in this Engineering Statement for Eutelsat 172B and for the publicly available FCC filings from O3b. The details of the calculations are shown in Table 3, which indicate that the operation of the Eutelsat 172B system and corresponding HPT Gateway in the bands 28.6‐29.1 GHz and 18.8‐ 19.2 GHz will have a negligible impact on the O3b satellite network. Specifically, from Table 3 it can be seen that the calculated ΔT/T values are all well below 6%, with a maximum ΔT/T value of 0.4%. Furthermore, it should be noted that the uplink EIRP density reflects a rain margin of over 13 dB. The Ka‐band uplink employs power control. Therefore, these uplink interference values would only be experienced a small fraction of time and in most cases, the interfering path would also experience significant rain fade. Finally, the uplink antenna sidelobe performance exceeds the Section 25.209 specification by over 10 dB. Similarly, it can be seen that the impact of O3b on the operation of the Eutelsat 172B network results in a maximum ΔT/T value of 4.9%.
