MSAT (Mobile Satellite) is a satellite-based mobile telephony service developed by the National Research Council Canada (NRC). 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 Communications of Canada referred to its MSAT satellite as MSAT-1, while American Mobile Satellite Consortium (now Ligado Networks) referred to its MSAT as AMSC-1, with each satellite providing backup for the other.

History

[1]

Phaseout

MSAT-1 and MSAT-2 have had their share of problems. Mobile Satellite Ventures placed the AMSC-1 satellite into a 2.5 degree inclined orbit operations mode in November 2004, reducing station-keeping fuel usage and extending the satellite's useful life.[7]

On January 11, 2006, Mobile Satellite Ventures (MSVLP) (changed name to SkyTerra, then became by acquisition LightSquared, then after bankruptcy Ligado Networks) announced plans to launch a new generation of satellites (in a 3 satellite configuration) to replace the MSAT satellites by 2010. MSV has said that all old MSAT gear would be compatible with the new satellites.[8][9]

Services Delivered via MSAT

The following services are singularly dependent upon the continued operation of the MSAT satellite:
