1996年3月13日,自主运行生存能力/空间试验实验平台(TAOS/STEP)技术卫星由金牛座(TAURUS)火箭从范登堡空军基地发射到105°倾角的近圆形轨道上。这颗卫星有两个用途:1)试验多途径获取快速一跟踪模块化卫星的新概念;2)在空间试验一套菲利普实验室的有效载荷。TAOS有效载荷包括MICROCOSM公司的自主导航系统(MANS),两个巴恩斯工程公司的双圆锥扫描器,两台霍尼韦尔的通用超大规模集成电路(VHSIC)星载计算机,一台洛克韦尔全球定位系统接收器,一个军标1553B数据总线,两个激光敏感器和一个雷达敏感器。有效载荷的实验周期大约一年半,尽管STEP卫星的惯性测试元件、TAOS有效负载的一台通用VHSIC星载计算机以及GPS接收器的射频链路出了故障,但实验仍取得极大的成功。
On March 13, 1996, the TAOS / SAT satellite was launched by the TAURUS rocket from Vandenberg Air Force Base into a nearly circular orbit at a 105 ° dipole. The satellite serves two purposes: 1) experimenting with multiple approaches to acquiring a new concept of fast-tracking modular satellites; and 2) testing a set of Philips lab payloads in space. TAOS payloads include MICROCOSM’s Autonomous Navigation System (MANS), two Barnes & Engineering’s double cone scanners, two Honeywell VHSIC on-board computers, a Rockwell GPS receiver, a military standard 1553B data bus, two laser sensors and a radar sensor. The experimental period of the payload was about a year and a half, and the experiment was a success, despite the fact that the inertial test element of the STEP satellite, a generic VHSIC onboard TAOS payload, and the RF link of the GPS receiver failed.
