IBFS_SESSTA2014082100668_1058802

Exhibit A Page 1 of 8 REQUEST FOR SPECIAL TEMPORARY AUTHORITY By this application, SES Government Solutions, Inc., formerly known as Americom Government Services, Inc. (“SES-GS”) respectfully requests special temporary authority (“STA”) for a period of 30 days to operate an earth station at MacDill Air Force Base in Tampa, FL, that will communicate with the O3b Ka-band non- geostationary orbit fixed-satellite service (“NGSO FSS”) satellite fleet. As discussed below, grant of the requested authority is in the public interest as it will allow SES-GS to test and evaluate O3b services that may be of interest to U.S. government customers. SES-GS does not seek to provide commercial services to end users. In order to accommodate the schedule for testing, SES-GS requests action on this STA by no later than October 15. Background: SES-GS provides reliable and secure commercial satellite services to U.S. Government, Intelligence and Civilian agencies. SES-GS believes that adding access to the O3b network may be an attractive option for such customers. Because of its lower NGSO orbit, the O3b fleet can offer service with reduced latency at affordable rates. In order to introduce prospective customers to the capabilities of the O3b network, SES-GS has procured a set of antennas that can communicate with the O3b constellation and can be used to evaluate and demonstrate the O3b services. SES-GS initially sought and was granted Commission authority to locate these antennas at a site in Bristow, VA, 1 but now proposes to relocate the antennas to Tampa. Under the requested STA, SES-GS seeks to operate the antennas only for testing and providing demonstrations and will not be offering service to customers for a fee. Protection of Authorized Stations: SES-GS seeks authority herein to communicate with O3b in a subset of the Ka-band spectrum that O3b has been licensed 1 See SES Government Solutions, Inc., File Nos. SES-STA-20131022-00888 (grant- stamped Jan. 6, 2104); SES-STA-20131022-00887 (grant-stamped Jan. 31, 2014); & SES-STA-20140612-00517 (grant-stamped July 29, 2014).

Exhibit A Page 2 of 8 to use for its existing U.S. earth stations. 2 Specifically, SES-GS requests authority for the following O3b beams: Beam 3: 28.172-28.388 GHz uplink and 18.372-18.588 GHz downlink Beam 4: 28.601-28.817 GHz uplink and 18.801-19.017 GHz downlink Beam 5: 28.855-29.071 GHz uplink and 19.055-19.271 GHz downlink NGSO FSS has a primary allocation in the beam 4 and 5 spectrum, but does not have a primary U.S. allocation in the band 3 spectrum. However, SES-GS demonstrates herein that its proposed communications with the O3b network in the beam 3 frequencies will not cause interference to primary operations, and SES-GS will not claim interference protection from such operations. LMDS in the 28.172-28.350 GHz Band: In most of the O3b uplink spectrum for beam 3, terrestrial local multipoint distribution service (“LMDS”) systems are primary, and FSS has a secondary allocation. In order to ensure that its proposed secondary operations would not cause interference to LMDS operations, SES-GS asked Comsearch to identify all existing and proposed terrestrial networks in the vicinity of the Tampa site. Comsearch notified each of these operators of the technical parameters of the planned SES-GS transmissions. In the attached report, Comsearch confirms that it did not receive any objections to the proposed operations from any of the potentially affected terrestrial systems. The Commission has previously indicated that secondary FSS operations in the 27.6-28.35 GHz band are “for the purpose of providing limited gateway-type service.” 3 SES-GS believes that the focus of these Commission’s statements has been on ensuring that FSS operations are compatible with LMDS by limiting the number and 2 See O3b Limited, Call Sign E130021, File No. SES-LIC-20130124-00089 (“O3b Texas Application”), granted June 20, 2013 (“O3b Texas License”), Section C (authorizing operations in the 17.8-18.6 GHz, 18.8-19.3 GHz, 27.6-28.4 GHz, and 28.6-29.1 GHz bands); O3b Limited, Call Sign E100088, File No. SES-LIC-20100723-00952 (“O3b Hawaii Application”), granted Sept. 25, 2012 (“O3b Hawaii License”), Section C (same). 3 Rulemaking to Amend Parts 1, 2, 21, and 25 of the Commission’s Rules to Redesignate the 27.5-29.5 GHz Frequency Band, to Reallocate the 29.5-30.0 GHz Frequency Band, to Establish Rules and Policies for Local Multipoint Distribution Service and for Fixed Satellite Services, First Report and Order and Fourth Notice of Proposed Rulemaking, 11 FCC Rcd 19005, 19025, ¶ 45 (1996).

Exhibit A Page 3 of 8 ubiquity of FSS terminals permitted to use the spectrum. The proposal by SES-GS to operate at a single site in Tampa is clearly consistent with this underlying rationale. Furthermore, as noted above, LMDS systems in the vicinity of the site have been notified of the proposed SES-GS operations and have not objected. Accordingly, grant of the requested SES-GS STA will not undermine the primary spectrum rights of LMDS systems. GSO FSS in the 28.350-28.388 GHz and 18.372-18.588 GHz Bands: In the remaining segment of the beam 3 uplink frequencies, the spectrum is allocated to GSO FSS uplinks on a primary basis, with a secondary allocation for NGSO FSS uplinks. GSO FSS downlinks are primary throughout the beam 3 downlink spectrum, and there is no NGSO FSS allocation in this segment. Uplink transmissions from the proposed SES-GS earth station will not cause harmful interference to primary GSO FSS networks. In support of its Hawaii application, O3b demonstrated that its proposed operations at that site would comply with ITU uplink EPFD limits applicable to the 28.35-28.4 GHz band. 4 This showing was based on the power levels of the earth station and the angular separation between the O3b and geostationary orbits as viewed from the Earth. In its later Texas application, O3b cross-referenced the O3b Hawaii Application and demonstrated that because the Texas site is further north than the Hawaii location, the angular separation is greater, providing a greater margin of compliance. 5 The SES-GS proposed Tampa site is also further north than O3b’s Hawaii location, and the SES-GS antennas will operate at lower power levels than the O3b Hawaii or Texas antennas. 6 Accordingly, for the reasons set forth in the O3b Hawaii and Texas Applications, the proposed SES-GS operations will comply with the applicable ITU EPFDup limits. As a result, grant of STA 4 O3b Hawaii Application, Narrative at 14-15 & Technical Appendix at 26-28. 5 O3b Texas Application, Narrative at 6. 6 Specifically, the maximum earth station EIRP density transmitted by the proposed SES-GS 1.8 meter Tampa earth station for a 216 MHz signal is 21.5 dBW/4kHz, which is equivalent to 31.5 dBW/40kHz. This results in an input power spectral density of -31.5 dBW/4kHz. Assuming a 32 - 25 log(Ɵ) gain mask, the off-axis gain of the transmitting earth station for an off-axis angle of 7.4° is 2.8 dBi, resulting in a worst-case off-axis EIRP density towards the GSO of -28.7 dBW/4kHz or -18.7 dBW/40kHz.

Exhibit A Page 4 of 8 for use of the 28.35-28.4 GHz band on a secondary basis to communicate with the O3b constellation is consistent with Commission precedent. 7 SES-GS proposes to use the 18.372-18.588 GHz band on a non- conforming basis. SES-GS acknowledges that it is not entitled to protection from interference caused by primary GSO FSS operations in this spectrum. Furthermore, O3b has demonstrated that transmissions from its space stations will comply with the limits developed by the ITU to protect GSO FSS networks from unacceptable interference. 8 O3b’s compliance demonstration is based on the angular separation between the O3b and GSO orbits when viewed from the earth, which increases for latitudes further from the equator. 9 SES-GS seeks authority here for operations in Tampa that are at a higher latitude than the O3b authorized site in Hawaii, and accordingly the analysis provided in the O3b Hawaii Application supports grant of authority here. Earth Station Technical Parameters: SES-GS is attaching the following documents to provide the technical details of the operations proposed under the requested STA: 1. Schedule B. Although SES-GS is not seeking a permanent license for the Tampa demonstration site, SES-GS is providing as Annex 1 hereto a Schedule B with the applicable technical parameters for the Commission’s convenience. 2. Comsearch report. As discussed above, Comsearch identified and notified the 28 GHz terrestrial networks in the vicinity of the Tampa site. Attached as Annex 2 is the report confirming that no terrestrial licensee objected to the proposed operations of SES-GS. 7 See, e.g., O3b Texas License, Provisions 90086 and 90087 (specifying that transmissions from the earth station are secondary in the 27.6-28.4 GHz band and must comply with ITU EPFD requirements); O3b Hawaii License, Provisions 90039 and 90040 (same); Northrop Grumman Space & Missions Systems Corp., 24 FCC Rcd 2330, 2354 at ¶¶ 72-73 (Int'l Bur. 2009) (authorizing NGSO uplink operations on a secondary basis in primary GSO spectrum conditioned on compliance with ITU EPFD limits); contactMEO Communications, LLC, 21 FCC Rcd 4035, 4043-44 at ¶¶ 23-24, (Int'l Bur. 2006) (same). 8 See O3b Hawaii Application, Narrative at 12-14 & Technical Appendix at 22-26. 9 See id.

Exhibit A Page 5 of 8 3. Link budgets. Representative link budgets for the Tampa earth station are provided in Annex 3. In addition, SES-GS incorporates by reference herein technical materials it previously provided: 1. Antenna patterns. The Tampa site will use the same 1.8 meter antennas, manufactured by General Dynamics SATCOM Technologies, that were used at the SES-GS Bristow site. The antenna patterns were submitted as Annex 3 in File No. SES-STA- 20131022-00887. 2. Radiation hazard study. SES-GS has performed an analysis of the maximum radiofrequency levels emitted from the satellite communications antenna, and it was submitted as Annex 5 in File No SES-STA-20131022-00887. Finally, SES-GS incorporates by reference herein technical materials provided by O3b: 1. Schedule S and beam contour description. In October 2013, O3b provided supplemental information regarding its constellation in connection with O3b’s application for a blanket license for Earth Stations on Vessels. This set of data included a revised Schedule S and responses to specific FCC questions. See O3b Limited, Call Sign E130098, File No. SES-AMD-20131025-01138, filed Oct. 25, 2013, Completed Schedule S and O3b Reply. The operational characteristics of the proposed SES-GS Tampa terminal are within all aspects of the envelope defined for user terminals in O3b’s Schedule S. Furthermore, the beam contours for the proposed operations can be derived from the formulas O3b supplied on page 10 of its Reply. 2. Service area definition. The SES-GS Tampa location falls within the “U” service area identified in the O3b revised Schedule S, which includes all locations on Earth with elevation angles to the operational O3b satellites greater than 3 degrees. 3. U.S. government coordination. As explained in the O3b Hawaii Application, coordination of the O3b NGSO satellite system has been completed, and the coordination agreement has been provided confidentially to the Commission. See O3b Hawaii Application, Attachment A at 33, Section A.12. O3b has advised SES-GS that the agreement contemplates the operation of U.S. earth stations. 4. Compliance with PFD limits. O3b has shown that the power flux density (“PFD”) of the O3b system complies with all applicable FCC

Exhibit A Page 6 of 8 limits. See O3b Limited, Call Sign E130107, File No. SES-LIC- 20130618-00516, Technical Supplement filed July 24, 2013 at 6-8. This showing is based on a worst-case methodology to calculate the maximum EIRP density produced by the O3b downlinks. The proposed SES-GS Tampa earth station will be operated with O3b downlink signals that are below this maximum EIRP density level. 5. Notification of satellite operational flexibility. O3b has advised SES-GS that O3b has filed new information with the Commission concerning an expansion of the possible configurations in which O3b positions its NGSO satellites. See, e.g., O3b Limited, Call Sign E130107, File No. SES-AMD-20140814-00653, Exhibit. SES-GS has reviewed the O3b document and incorporates it by reference herein. U.S. Market Access: The O3b Hawaii Application included a showing that allowing U.S. earth stations to communicate with the foreign-licensed O3b NGSO constellation is consistent with U.S. market access policies, 10 as those policies are set forth in the DISCO II framework 11 and codified in Section 25.137. 12 The Commission granted the application, thereby authorizing communication between the Hawaii earth station and the O3b satellite fleet. 13 Subsequent to that grant, no change has occurred in the O3b satellite network’s operating parameters or the services that the network will be used to provide. Under these circumstances, no additional showing is needed to allow SES-GS to use its proposed Tampa antennas to communicate with the O3b satellite constellation. 14 In any event, the SES-GS Tampa antennas will be used for evaluation and demonstration purposes only, and not for commercial services. As a result, grant of the requested authority to communicate with the O3b constellation will have no effect on competition within the U.S. 10 See O3b Hawaii Application, Legal Narrative at 10-24. 11 See Amendment of the Commission’s Policies to Allow Non-U.S. Licensed Space Stations providing Domestic and International Service in the United States, Report & Order, 12 FCC Rcd 24094 (1997) (“DISCO II”). 12 47 C.F.R. § 25.137. 13 See O3b Hawaii License, Section D (authorizing communications with the U.K.- licensed O3b NGSO satellite system). 14 See DISCO II, 12 FCC Rcd at 24176, ¶ 192.

Exhibit A Page 7 of 8 Waiver Requests: SES-GS requests grant of any necessary waiver of the Commission’s rules in connection with the instant STA request. Such waiver is consistent with Commission policy: The Commission may waive a rule for good cause shown. Waiver is appropriate if special circumstances warrant a deviation from the general rule and such deviation would better serve the public interest than would strict adherence to the general rule. Generally, the Commission may grant a waiver of its rules in a particular case if the relief requested would not undermine the policy objective of the rule in question and would otherwise serve the public interest. 15 Section 25.145(c): Section 25.145(c) of the Commission's rules requires Ka-band NGSO systems to meet global and U.S. service coverage requirements. 16 O3b has explained that its network, which was designed with a focus on providing service to emerging markets and areas without significant terrestrial broadband infrastructure, cannot meet these requirements. 17 O3b argued that granting a waiver of the coverage requirements to allow access to the O3b network would further, not undermine, achievement of the rule’s purpose – fostering seamless global communications. 18 The Commission granted a waiver of the rule for both the O3b Hawaii and Texas gateway and TT&C earth stations, but stated that the grant was without prejudice to action on any waiver request to provide additional U.S. services. 19 SES-GS seeks grant of any necessary waiver of Section 25.145(c) in connection with the instant STA request. As with the O3b Hawaii and Texas stations, the proposed SES-GS Tampa antennas will not provide commercial services to end 15 PanAmSat Licensee Corp., 17 FCC Rcd 10483, 10492 (Sat. Div. 2002) (footnotes omitted). 16 47 C.F.R. § 25.145(c). 17 See O3b Limited, Call Sign E100088, File No. SES-LIC-20100723-00952 (“O3b Hawaii Application”), Legal Narrative at 21-22. 18 Id. at 22. 19 See O3b Hawaii License, Provision 90044; O3b Texas License, Provision 90044.

Exhibit A Page 8 of 8 users. Instead, the antennas will be operated only for purposes of evaluating the capabilities of the O3b network and demonstrating those capabilities to prospective customers interested in using O3b capacity for their communications needs, whether outside or inside the U.S. No fees will be charged to customers for these demonstrations, and accordingly the proposed operations will have no effect on competition in the U.S. In these circumstances, preventing SES-GS from communicating with the operational O3b global satellite network because that network does not comply with Commission coverage requirements would serve no conceivable public interest objective. Section 25.210(i)(1): O3b has also explained that its satellite constellation does not comply with the minimum cross-polarization isolation requirement for FSS systems in Section 25.210(i)(1). 20 The Commission granted a waiver of this rule in the O3b Hawaii and Texas Licenses. 21 For the same reasons, SES-GS requests that the Commission grant any necessary waiver of Section 25.210(i)(1) in connection with the instant STA request. Conclusion: The requested STA will allow SES-GS to evaluate and demonstrate the O3b network’s operational capabilities and will not result in harmful interference to other authorized spectrum users. Thus, grant of the STA will serve the public interest. 20 See O3b Hawaii Application, Legal Narrative at 22-23. 21 See O3b Hawaii License, Provision 90041; O3b Texas License, Provision 90041.
