IBFS_SESSTA2017102501206_1296127

                            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 Isabela, Puerto
Rico (“Isabela Earth Station”) in the conventional C‐band. The Isabela 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 27, 2017.2

         The Isabela 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 Isabela Earth Station to supplement these services. Grant of this STA request will serve
the public interest because the Isabela Earth Station will be used to allow SES’s customer to provide
internet connectivity throughout its Puerto Rican facility. This will allow a large local employer to resume
its normal business operations and provide an economic boost to the region as it recovers from the
impact of the recent storms.

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.

20061006‐00118, granted Dec. 7, 2006.
2
  Actual service will be provided from October 28th 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).

Conclusion

         The requested STA will allow SES to help restore connectivity to its customer’s facility in 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 27, 2017.

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.
