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 |  |
L-band SAR
L-band Synthetic Aperture Radar | Being developed
| L-band SAR instrument offering full polarimetry, high spatial resolution, high sensitivity, low ambiguity ratios and capability for repeat-pass & single-pass cross-track interferometry to measure surface deformation of vegetated terrain, soil moisture, land cover classification, crop type discrimination and its temporal analysis. Furthermore, it will monitor Polar ice sheets and ice caps, and the sea-ice conditions (i.e. type, drift, deformation, concentration, lead fraction), as well as contribute to the European maritime situational awareness. | n/a | |
SGR-ReSI-Z
Space GNSS Receiver - Remote Sensing Instrument (Zynq based) | Being developed
+/-90 % | Ocean winds, waves, soil moisture, flooding, ice, snow | n/a | |
