COMSAT, Inc. Request for Extension of Special Temporary Authority to Operate Santa Paula Teleport 12.8 Meter Hub Antenna to Communicate With Inmarsat 3F2 Satellite Using L-band Frequencies to Support Inmarsat Testing During Westward Drift of Satellite File Number SES-STA-20190424-00540 Call Sign KB34 COMSAT, Inc. (“COMSAT”) respectfully requests an extension of Special Temporary Authority (“STA”) effective June 1, 2019 to allow COMSAT to continue to operate its Santa Paula, California Teleport 12.8 Meter Hub Antenna (SAPA 12.8M) to communicate with the Inmarsat 3F2 Satellite (I3F2) using L-band Frequencies to support Inmarsat testing during westward drift of I3F2. Inmarsat advises that it now intends to deorbit this satellite and so the L-band will also be used for a backup link with the satellite during the deorbiting process. Inmarsat has requested COMSAT to provide a C- band link to the satellite for TT&C purposes during the deorbit process. A separate Application will be filed for STA for these communications. Grant of the STA is in the public interest because Inmarsat services supported by I3 satellites include maritime services used for Safety at Sea as well as services used by various U.S. agencies. It is therefore respectfully requested that STA as described above be granted for a period of 30 days, effective June 1, 2019. Any questions with respect to this matter may be directed to James G. Lovelace at 571-599-3643.
