RADARSAT Constellation Mission (RCM) Space Segment

2016-04-07 - The RADARSAT Constellation Mission Space Segment consists of a constellation of three identical satellites flying in low-Earth orbit (586 km to 615 km above the Earth). Each of the satellites in the constellation is made up of a bus and a synthetic aperture radar (SAR) payload. There is also a secondary payload—an automated identification system (AIS) for ships—that is used independently or in conjunction with the SAR. (Credit: Canadian Space Agency)
