THEA Satellite STA File#: 0548-EX-ST-2019 THEA Satellite Special Temporary Authority (“STA) Attachment 1 to Form 442 STA File #: 0548-EX-ST-2019 SpaceQuest, Ltd. (“SpaceQuest”), pursuant to Section 5.61 of the Commission’s rules, respectfully seeks special temporary authorization (“STA”) to downlink the experimental data from its THEA non-geostationary satellite to RBC Signals ground station in Fairbanks, Alaska using SpaceQuest’s currently authorized S-Band frequency of 2201 MHz (FCC #: 0176-EX-CN-2018). The SSC Esrange, Sweden ground station referenced in the original THEA license application has incompatible equipment for downloading the THEA experimental data. SpaceQuest now has an urgent need for a temporary alternative as it could take 3-6 months before the situation in Esrange is corrected. SpaceQuest has lost its capability to perform as authorized and therefore requests expedited consideration of this STA. The primary satellite mission of the THEA satellite is to test an experimental spectrum survey payload developed by Aurora Insight, a U.S. company. The Aurora payload is an experiment to demonstrate and validate the ability of its flight computer firmware to monitor, process and generate relevant measurements of the spectral environment in the 1.35 to 8.0 GHz band using a novel wideband antenna. The S-Band assignment will be used to download selected mission data from the Aurora payload. The SpaceQuest receive-only S-Band transmissions will be intermittent and on an unprotected and non-interference basis, approximately two or three times per day when the satellite passes over the ground station. In addition, SpaceQuest expressly acknowledges that any grant of this STA request is without prejudice to Commission action on other requests for authority made by SpaceQuest. Extraordinary circumstances exist to grant this request - the critical need for a U.S. authorized satellite to operate as intended including fulfilling its experimental mission that will promote U.S. leadership in the development of next-generation satellite technologies being tested by the SpaceQuest satellites.
