Summary
RADARSAT-1 is an Earth observation satellite equipped with C-Band SAR, manufactured by SPARM/BALL and owned by CSA (Canadian Space Agency). It was launched on November 4, 1995, from AFWTR using a Delta 7920-10 launch vehicle. The spacecraft has dimensions of 4.2 meters in length, 2.8 meters in diameter, and a span of 15 meters. RADARSAT-1 weighs 2750 kilograms at launch with the same dry mass and operates on power generated from two deployable solar arrays and batteries. Its mission was planned for five years but achieved an operational lifespan of 17 years. The satellite's shape is described as Box + 2 Pan, with a RCS of 5.9319. It has no recorded ADCS or color information, and its primary purpose is Earth observation via radar technology.
