TechDemoSat-1: Launched 2014

UK industry and academia worked together with Surrey Satellite Technology Ltd (SSTL) on a new innovative satellite to trial UK space technologies and provide an ‘in-orbit test facility’ for innovative UK payloads and software.

 At around one meter cubed (roughly the size of a washing machine) and a surprisingly light mass of around 150kg, TechDemoSat (TDS-1) carried eight payloads plus a mixture of heritage and new product development systems from SSTL.   

TechDemoSat-1 demonstrated the first use of reflected GPS signals to measure sea-state and generate Delay Doppler Maps on board the satellite using an SSTL developed instrument called the SGR-ReSI.

In May 2019, TechDemoSat-1 reached the end of its mission life and a drag sail supplied by Cranfield University was deployed to increase the rate of orbital decay.
