REQUEST FOR SPECIAL TEMPORARY AUTHORITY SES Americom, Inc. (“SES”) respectfully requests earth station Special Temporary Authority (“STA”) for 30 days to test 131.2x 141.8 x 29.8 centimeter antenna designated RaySat ER7000 for compatibility with SES’s satellites in the conventional Ku-band.1 The testing will occur in Port St. Lucie, FL, USA, and the antenna will communicate with the SES-10 spacecraft at 66.9W (Call Sign S2950).2 SES seeks STA to conduct the testing beginning September 9, 2019 and asks for Commission action consistent with that timing. Grant of the requested STA is in the public interest because it will accelerate testing of a terminal used for mobile connectivity for ESIMs in remote areas, specifically for railway connectivity in Alaska. Furthermore, the proposed testing in the conventional Ku-band will be limited and will not cause harmful interference to any terrestrial or satellite operators. SES will also conduct operations on an unprotected, non-interference basis. For the foregoing reasons, SES Americom respectfully requests that the Commission grant it a 30-day STA to test its RaySat ER7000 antenna with SES- 10 in the conventional Ku-band beginning September 9, 2019. 1 The proposed operations are summarized in Attachment 1. 2 New Skies Satellites B.V., Call Sign S2950 (modification granted Mar. 10, 2017).
