REQUEST FOR SPECIAL TEMPORARY AUTHORITY SES Americom, Inc. (“SES”) respectfully requests earth station Special Temporary Authority (“STA”) for 30 days to demonstrate a new 30 centimeter antenna designated GetSat MicroSat LM to the U.S. Department of Defense in the conventional Ku- band.1 The demonstration will occur in Pinehurst, North Carolina, and the antenna will communicate with the SES-15 spacecraft at 129.15° W.L. (Call Sign S2951).2 SES seeks STA to conduct the demonstration beginning March 25, 2018, and asks for Commission action consistent with that timing. Grant of the requested STA on an expedited basis is in the public interest because it will allow the US Government to assess the benefits of the new antenna for operations in remote areas. Furthermore, the proposed operations 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 on an expedited basis to demonstrate its GetSat MicroSat LM antenna with SES-15 in the conventional Ku-band beginning March 25, 2018. 1 The proposed operations are summarized in Attachment 1. 2 SES Satellites (Gibraltar) Ltd, (Call Sign S2951) File No. SAT-MPL-20160718-00063, granted Dec. 14, 2016, as modified by File No. SAT-MPL-20170914-00130, granted Nov. 22, 2017.
