In-orbit validation of the fmpl-2 instrument—the gnss-r and l-band microwave radiometer payload of the fsscat mission
The Flexible Microwave Payload-2 is the GNSS-R and L-band Microwave Radiometer Payload on board Cat-5/A, one of the two 6-unit CubeSats of the FSSCat mission, which were successfully launched on 3 September 2020 on Vega flight VV16. The instrument occupies nearly a single unit of the CubeSat, and it...
