                   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.
