The RADARSAT Constellation Mission (RCM) is Canada's third generation of Earth observation satellites, launched June 12, 2019 with three identical satellites working together. RCM is the first mission in the RADARSAT program to carry dual payloads, combining a SAR instrument with an Automatic Identification System (AIS) instrument for ship detection. The three satellites cover Canada and areas of interest elsewhere more frequently than earlier RADARSAT missions.
