SGR-ReSI-CDHS
Space GNSS Receiver - Remote Sensing Instrument, CoreDHS avionics
Operational
Ocean winds, waves, soil moisture, flooding, ice, snow. Similar to SGR-ReSI-Z, but with a smaller Zynq, and only supports 2 RF channels, only allowing collection of single frequency and single polarisation. n/a
Imaging Microwave Radiometer
Imaging Microwave Radiometer
Being developed
A conical scanning total power radiometer operating in 5 bands (L/C/X/Ku/Ka) to provide high-spatial resolution microwave imaging radiometry measurements and derived products with continuous global coverage and sub-daily revisit in the polar regions and adjacent seasn/a
MWI
Microwave Imager
Being developed
Measure cloud liquid water content, solid/liquid precipitation information, total column water vapour and temperature profiles, sea ice parameters, sea surface temperature, sea surface wind speed.n/a
SGR-ReSI-Z
Space GNSS Receiver - Remote Sensing Instrument (Zynq based)
Being developed
