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 LightSquared) referred to its MSAT as AMSC-1, with each satellite providing backup for the other. ==History== * April 7, 1995 - MSAT-2 (aka AMSC-1) launched from Cape Canaveral, Launch Complex 36, Pad A, aboard Atlas IIA * May 1995 - testing causes overheating and damage to one of eight hybrid matrix amplifier output ports aboard MSAT-2〔(【引用サイトリンク】title=AMERICAN MOBILE SATELLITE CORPORATION AND SUBSIDIARIES: Form 10-Q ) 〕 * April 20, 1996 - MSAT-1 launched from Kourou, French Guiana aboard Ariane 42P〔(【引用サイトリンク】title=MSAT-1 TO LAUNCH APRIL 20TH )〕〔(【引用サイトリンク】title=Boeing: Chronology of Launches )〕 * May 15, 1996 - Reported failures of two solid state power amplifiers (SSPAs) and one L-band receiver on separate occasions aboard MSAT-2.〔 * May 4, 2003 - MSAT-1 loses two power amplifiers.〔(【引用サイトリンク】title=Service Outage - November 30, 2003 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MSAT」の詳細全文を読む スポンサード リンク
