It was the thirteenth of nineteen Block IIA GPS satellites to be launched. USA-94 was launched at 12:38:00 UTC on 30 August 1993, atop a Delta II carrier rocket, flight number D222, flying in the 7925-9.5 configuration. The launch took place from Launch Complex 17B at the Cape Canaveral Air Force Station, and placed USA-94 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor. On 1 October 1993, USA-94 was in an orbit with a perigee of , an apogee of , a period of 718 minutes, and 54.8 degrees of inclination to the equator. It broadcast the PRN 30 signal, and operated in slot 4, and later 5, of plane B of the GPS constellation. The satellite had a mass of and a design life of 7.5 years.〔 It was decommissioned on 1 May 2013, after almost 20 years in orbit.〔(【引用サイトリンク】title=NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2013027 )〕 ==References== 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「USA-94」の詳細全文を読む スポンサード リンク
