Canadian surveillance satellite system now operational
DAVID PUGLIESE, OTTAWA CITIZEN Canada's RADARSAT Constellation Mission is now operational and federal government departments will start receiving data from the surveillance and earth observation satellites. The RADARSAT Constellation Mission, or RCM, was launched June 12 aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. The constellation of three satellites will provide daily images of Canada's territory and maritime approaches, as well as images of the Arctic, up to four times a day, according to the Canadian Space Agency. It will have daily access to 90 per cent of the world's surface. The RCM is also equipped with an Automatic Identification System (AIS), allowing improved detection and tracking of ships, including those conducting illegal fishing, the CSA noted. The constellation is orbiting Earth at an altitude of 600 km. Each of the satellites has a life expectancy of seven years. The Canadian government owns the satellites. The three spacecraft were assembled in the Montreal area by the prime contractor MDA. Over a dozen federal government departments and agencies will use RCM images. It is estimated that the Canadian government will use approximately 250,000 images from the satellite constellation every year. That represents a fiftyfold increase from the days of the first RADARSAT-1 system, according to the Canadian government. The majority of the data transmitted from RCM is expected to be used by the Canadian Forces and the Department of National Defence. RCM follows the highly successful RADARSAT-1, launched by NASA in 1995, and RADARSAT-2, put into orbit by the Russians in 2007. Initial work on RCM began in 2005. The project cost an estimated $975 million. The RCM project was led by the Canadian Space Agency and supported by its principal users: the Department of National Defence, Fisheries and Oceans Canada, Agriculture and Agri-Food Canada, Environment Canada, Natural Resources Canada and Public Safety Canada. https://ottawacitizen.com/news/national/defence-watch/canadian-surveillance-satellite-system-now-operational
