The RADARSAT Constellation Mission (RCM) is a three-spacecraft fleet of Earth observation satellites by the Canadian Space Agency. With satellites smaller than RADARSAT-2,[3] the RCM will provide new applications—made possible through the constellation approach—as well as continuing to provide C-band radar data to RADARSAT-2 users.[4] Improvements include more frequent area coverage of Canada and reduced risk of a service interruption.[5]

The launch of the three satellites that will form the constellation is scheduled for February 18, 2019.[2][6] Manufacturer MDA contracted the launch to SpaceX with a Falcon 9 rocket.[7]

Overview

The RADARSAT Constellation Mission (RCM) includes three identical Earth observation satellites. The prime contractor on the project is MacDonald Dettwiler and Associates and it was designed for three main uses:[8][9]

  • Maritime surveillance (ice, surface wind, oil pollution and ship monitoring)
  • Disaster management (mitigation, warning, response and recovery)
  • Ecosystem monitoring (agriculture, wetlands, forestry and coastal change monitoring)

Its synthetic aperture radars (SAR) have a mass of 400 kg each, and a resolution of 1 × 3 m.[1]
