IBFS_SESSTA2017102001188_1293835

REQUEST FOR SPECIAL TEMPORARY AUTHORITY SES Americom, Inc. (“SES”), pursuant to Section 25.120 of the Commission’s rules, respectfully requests Special Temporary Authority (“STA”) for 30 days to operate an earth station in Ceiba, Puerto Rico (“Ceiba Earth Station”) in the conventional C‐band. The Ceiba Earth Station will communicate with AMC‐18 at 104.95° W.L., which is on the Commission’s Approved Space Station List for service to the U.S. market.1 SES seeks a 30‐day STA beginning no later than October 24, 2017.2 The Ceiba Earth Station will be integrated into a temporary system with other operators to help restore local wireless service in Puerto Rico. As discussed below, grant of the requested authority is in the public interest as it will allow SES to provide services that will benefit the population in Puerto Rico as it recovers from the recent hurricanes and rebuilds its telecommunications infrastructure. Public Interest Showing In the aftermath of Hurricane Maria, Puerto Rico lost most of its wireless coverage across the island, leaving residents without cellphone service.3 In recent reports, the Commission estimates that the vast majority of cell sites remain out of service.4 SES subsidiary O3b is currently providing capacity to temporarily enable local wireless services.5 Due to high demand for satellite services in the region, SES is deploying the Ceiba Earth Station to supplement these services. Grant of this STA request will serve the public interest because the Ceiba Earth Station will be used to bring local wireless networks in Puerto Rico online while the terrestrial infrastructure is being repaired. Earth Station Technical Parameters A description of the antenna and the proposed operations is provided in Annex 1, and Annex 2 sets forth the technical characteristics of the VertexRSI lightweight 2.4 meter terminal that will be used. Annex 3 contains a temporary uplink coordination report from Comsearch. Conclusion The requested STA will allow SES to help connect wireless services for the people of Puerto Rico as the local terrestrial networks are being repaired. Accordingly, and for good cause shown, SES respectfully requests that its STA be granted no later than October 24, 2017. 1 See Petition for Declaratory Ruling of SES Satellites (Gibraltar) Limited, Call Sign S2713, IBFS File No. SAT‐PPL‐ 20061006‐00118, granted Dec. 7, 2006. 2 Actual service will be provided from October 27th to November 7th. Given the urgent need to commence service immediately, SES respectfully submits that the circumstances justify grant of authority on less than three business days’ notice under Section 25.120(a). 3 See Elizabeth Weise, Puerto Rico is nearly entirely cut off from cellphone service, leading to low tech solutions, (Sept. 28, 2017), https://www.usatoday.com/story/tech/2017/09/28/puerto‐rico‐cell‐phone‐service‐tmobile‐att‐ hurricane/710775001/. 4 See, e.g., “Communications Status Report for Areas Impacted by Hurricane Maria,” (rel.

ANNEX 2 –Terminal Characteristics

Model 2.4m SF Flyaway Antenna Flyaway Antennas Description The VertexRSI lightweight 2.4-meter flyaway antenna is designed for worldwide transmit and receive operation in C, X and Ku-band. This portable antenna consists of a carbon fiber composite reflector and aluminum support structures. This results in a low-weight antenna with superior stiffness and high performance under wind loading conditions. The unique shape and the accurate reflector surface provide exceptionally low sidelobe and cross-polarization performance well within INTELSAT and EUTELSAT requirements. Repeatability is maintained with precision registration of the nine reflector segments and the feed support structure. The complete antenna system, including a single feed, is packaged in nine robust portable cases. Features „„ Carbon fiber reflector ƒƒ Lightweight, precision surface and high stiffness „„ Easy deployment ƒƒ Two-person assembly, captive hardware, precision alignment „„ INTELSAT type approved, EUTELSAT compliant „„ High performance ƒƒ Low sidelobes and high E.I.R.P. capability Options „„ Finishes ƒƒ Green, tan or per customer spec „„ Feeds ƒƒ Four-port, Co pol, CP/LP switchable, DBS, Ka-band ƒƒ Motorized polarization The Strength to Perform „„ Motorization ƒƒ Az/El motorized, tracking using pulse sensors or resolvers
