later served a number of roles. For some time it was the major Canadian ground receiving station for satellite communications, both for US satellites, and the Canadian Alouette 1. The DRTE Computer was used in this role too, calculating the path of the satellite over the PARL site, allowing the radar dish to be steered into the proper location to receive the signals from the quickly moving source. In 1968 the distance from the Algonquin Radio Observatory to the PARL site was measured to 2,143 km +/- 20 m. Today the Prince Albert Satellite Station is operated by Canada Centre for Remote Sensing a branch of Natural Resources Canada as a ground station for the following satellites: Landsat-8 RADARSAT-2 NEOSSat SCISAT References Laboratories in Canada Scientific organizations based in Canada Buildings and structures in Prince Albert, Saskatchewan Military research installations of Canada Natural Resources Canada
