众所周知,GPS(Golbal PositioningSystem)是由美国防部(DOD)研制的卫星全球导航系统,将于90年代初进入运行阶段。NASA决定包括下一代航天飞机在内的空间平台的主要导航系统将采用GPS方式,为此已经开始进行整体研究。不仅空间站采用GPS导航,而且欧洲航宇局(ESA)计划中的小型航天飞机Hermes也将以GPS和INS(惯性导航系统)为中心着手研究导航系统。只靠GPS一种方式得不到姿态情报,还要和INS方式组成复合系统才能提
As we all know, GPS (Golbal PositioningSystem) is a satellite global navigation system developed by the United States Department of Defense (DOD), will enter the operational phase in the early 90s. NASA decided that the main navigation system of the space platform, including the next generation of space shuttle, will adopt GPS mode, and overall research has begun for this purpose. Not only is space station GPS navigation, but the European Space Agency (ESA) planned small spacecraft Hermes will also focus on GPS and INS (inertial navigation system) as the center to study navigation systems. GPS alone can not get attitude information, but also with the INS system to form a composite system to mention
