| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| C-Band SAR | Operational +/-3 cm | Marine core services, land monitoring and emergency services. Monitoring sea ice zones and arctic environment. Surveillance of marine environment, monitoring land surface motion risks, mapping of land surfaces (forest, water and soil, agriculture), mapping in support of humanitarian aid in crisis situations. | n/a |  |
| OLI | Operational | Measures surface radiance, land cover state, and change (e.g., vegetation type). Used as multi-purpose imagery for land applications. | n/a | |
| OLI-2 | Operational | Measures surface radiance, land cover state, and change (e.g., vegetation type). Used as multi-purpose imagery for land applications. | n/a | |
| SAR (RADARSAT-2) | 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) | Operational | All-weather, C-band data to support ecosystem monitoring, maritime surveillance and disaster management. | n/a | |
| CAR | Approved | Panchromatic and multispectral (Vis/IR) measurements with high spatial resolution, with stereo capability for DEM generation. Applications in emergencies in general, agriculture, land use/land cover, change detection, urban environment, cartography, topography. | n/a | |
| LandIS | Proposed | Measures surface radiance, land cover state and change (e.g., vegetation type), and longwave termal infrared surface emittance. Used as multi-purpose imagery for land applications. | n/a | |
