Accuracy | Instrument Description | Measurement Technology | Timeline |
HRMX
High Resolution Multi Spectral | Operational
| For crops and vegetation dynamics, natural resources census, disaster management and large scale mapping of themes. | n/a |  |
SAR (RADARSAT-2)
Synthetic Aperture Radar (SAR) C band | Operational
| All-weather images of ocean, ice and land surfaces. Used for monitoring of coastal zones, polar ice, sea ice, sea state, geological features, vegetation and land surface processes. | n/a | |
SAR (RCM)
Synthetic Aperture Radar (SAR) C band | Operational
| All-weather, C-band data to support ecosystem monitoring, maritime surveillance and disaster management. | n/a | |
IRIS
Interferometric Radar Altimeter for Ice and Snow | Being developed
| Ku-band Interferometric Synthetic Aperture Radar Altimeter (with added Ka-band channel for snow depth retrieval and in combination with AMR-CR MW Radiometer for ice&snow classification and wet troposphere correction) to cover the needs for continuous monitoring of sea ice
thickness and land ice elevation measurement after Cryosat-2, with enhanced performance. | n/a | |
