Exhibit A Page 1 of 1 APPLICATION SES Government Solutions, Inc. (“SES-GS”) hereby seeks a license for a new earth station in Pago Pago, American Samoa, that will communicate with the O3b Ka-band non-geostationary orbit fixed-satellite service (“NGSO FSS”) satellite fleet. Operations of this earth station have commenced pursuant to special temporary authority (“STA”). See File Nos. SES-STA-20160426-00372 & SES-STA-20160624- 00604. Grant of the requested license is in the public interest as it will allow SES-GS to provide O3b capacity to the National Oceanic and Atmospheric Agency to support the provision by the National Weather Service of data on weather and climate, including warnings for the protection of life and property. SES-GS incorporates herein the information included in its initial STA request for this site, File No. SES-STA-20160426-00372. As noted in that request, the Commission has granted U.S. market access for the O3b constellation, authorizing U.S. earth stations to communicate with the O3b fleet. 1 Moreover, the antenna model that SES-GS is seeking to use has already been approved by the Commission for operations with the O3b network throughout the continental U.S., Hawaii, Puerto Rico, and the U.S. Virgin Islands. 2 For the Commission’s convenience, SES-GS is reattaching the radiation hazard study for this antenna that was included in the STA request, as well as a set of link budgets for the proposed operations. 1 See O3b Limited, Call Sign S2935, File Nos. SAT-LOI-20141029-00118 & SAT-AMD- 20150115-00004, granted Jan. 22, 2015 (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 was granted certain waivers in connection with its request for U.S. market access, including waivers of the geographical coverage requirements for Ka-band NGSO systems in Section 25.145(c) and of the cross-polarization isolation requirements in Section 25.210(i)(1). See id., Attachment to Grant at 3-4. To the extent necessary, SES-GS requests that these waivers be extended to the operations proposed in this license application. 2 See O3b Limited, Call Sign E140101, File No. SES-LIC-20141001-00781, granted June 8, 2015. A full set of patterns for this antenna model is already on file as a part of that application.

RADIATION HAZARD STUDY In this report SES Government Solutions, Inc. (“SES-GS”) analyzes the maximum radiofrequency (RF) levels emitted from the satellite communications antenna described below. The reference document for this study is OET Bulletin No. 65, Edition 97-01, Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, August 1997. 1. The following data is used throughout the analysis: 2. Density at Feed Flange The maximum power flux density at the surface of the feed flange is as follows: 3. Density at Main Reflector The maximum power flux density at the surface of the main reflector is as follows: 1

4. Density between Main Reflector and Ground The maximum power flux density in the area between the edge of the main reflector and the ground is as follows 5. Density within the Near Field The Near Field environment for a parabolic reflector antenna is contained within a cylinder with the same diameter as the main reflector which extends to a distance called the Near Field Extent Power within the Near Field is constant with the following maximum flux density: 6. Density at Transition Region The Transition Region is the area between the Near Field and Far Field regions where power decreases linearly with distance. The maximum power flux density within the Transition Region is located at the Near Field extent range and is calculated as follows: 7. Density at Beginning of the Far Field The Far Field region is the range at which power decreases inversely with the square of the distance. The maximum power flux density within the Far Field region occurs at the Far Field Boundary and is calculated as follows: 8. Range to Far Field General Population Exposure Limit In addition to the power flux density calculations at key locations, it’s valuable to locate the specific range at which MPE limits are reached to aid in managing exposure control. The following calculation shows the range at which the Far Field General Population MPE limit occurs: 2

9. Non-Ionizing Radiation Summary Flux Densities & Exposure Limits General Population Exposure Limit = 1.0 mW/cm2 Occupational Exposure Limit = 5.0 mW/cm2 Range to Key Points and General Population Exposure Limit Avoidance Methods 3

10. Conclusion The above analysis confirms the presence of potentially hazardous power flux densities at the terminals which will require physical and operation protections to manage General Population and Occupational Exposure. As appropriate, SES GS will use fencing, signage, and other measures to limit access to the relevant area. Procedures will be in place requiring that transmit power be turned off before work on the 2.4m antennas is performed. Where an enclosed area is necessary, the size of the enclosed area will consider the RF hazards and the surrounding terrain. The signage will clearly state the standard Radiation Hazard warning. Personnel with access to the antenna will be trained to ensure that the antennas are off before working in the vicinity or on the antenna systems directly. 11. Certification I hereby certify I have reviewed the engineering information submitted, and that it is complete and accurate to the best of my knowledge. /s/ Majid Borojeni Majid Borojeni Network Engineering Director SES Government Solutions April 26, 2016 4
