MSAT, short for Mobile Satellite, is a satellite-based mobile telephony service developed by the National Research Council of Canada. Supported by a number of companies in the US and Canada, MSAT hosts a number of services, including the broadcast of CDGPS signals. The MSAT satellites were built by Hughes (now owned by Boeing) with a 3 kilowatt solar array power capacity and sufficient fuel for a design life of twelve years. TMI of Canada referred to its MSAT satellite as MSAT-1, while American Mobile Satellite Consortium (now SkyTerra) referred to its MSAT as AMSC-1, with each satellite providing backup for the other.
