TechDemoSat-1 was a joint UKSA-ESA technology demonstration satellite mission launched in 2014. The satellite carried eight experimental payloads provided by UK space industry and academic institutions. Among the new technologies demonstrated by the satellite was GNSS reflectometry (by SSTL) using satellite navigation signals reflected from the sea surface for measuring sea ice cover, ocean surface wind, and sea state.Sea State Payload on TechDemoSat-1Spaceborne GNSS-Reflectometry on TechDemoSat-1: Early Mission Operations and ExploitationGNSS Reflectometry for Global Ocean Wind Services: the TechDemoSat-1 Success Story The mission ended in 2019 after the satellite successfully deployed an experimentral de-orbit drag sail (by Cranfield University) designed to increase the spacecraft's rate of orbital decay.DE-ORBIT SAIL DESIGN FOR TECHDEMOSAT-1
