RADARSAT Constellation Mission

Designed and built by MDA, this configuration consists of three satellites working together to collect data for the Government of Canada. The mission is focused on maritime surveillance, disaster management and ecosystem monitoring to protect our environment.

Capturing change

These satellites provide critical information following natural and man-made disasters – such as earthquakes, hurricanes, oil spills and flooding – which is used to measure damage and aid recovery efforts. Radar satellites can also map complex landscapes, and allow us to track shifting ice in the Arctic to help ships navigate, and to monitor environmental changes in large ecosystems, such as marshes, forests and farmland.


  • 592.7 km – The altitude of the satellites in orbit
  • 120° – The spacing between the three satellites on their orbital plane
  • 96.4 minutes – The time it takes each satellite to circle Earth
  • 15 – The number of orbits per day
