要为了支持在PRIRODA上进行的德国MOMS-2P飞行任务,提供其所需的轨道和姿态数据,根据与德国空间局(DARA)签订的合同开发一种称为MOMSNAV的高精度导航装置。MOMS(模块化多谱段光学扫描仪)和MOMSNAV预定于1995年年中发射。采用DGPS确定轨道和惯性姿态的导航装置包括一台星载GPS接收杌,一个冗余高精度陀螺装置,一个数据管理系统及一个电源控制和分配装置。结合地面GPS基准台站,通过事后处理可以提供5m定位精度和10′相对姿态确定精度。本文描述了MOMSNAV结构、基本系统和任务参数,对DGPS在大型空间站上应用的一些特殊问题进行了讨论。
In order to support the German MOMS-2P mission at PRIRODA, to provide the orbit and attitude data it needs, a high-precision navigation device called MOMSNAV was developed under a contract with the German Space Agency (DARA). MOMS (Modular Multi-spectral Optical Scanner) and MOMSNAV are scheduled to be launched in mid-1995. Navigation devices using DGPS to determine orbital and inertial pose include an on-board GPS receiver, a redundant high-precision gyro, a data management system, and a power control and distribution unit. Combined with ground-based GPS reference stations, 5m positioning accuracy and 10 ’relative attitude determination accuracy can be provided by post-processing. This article describes the MOMSNAV architecture, basic system and mission parameters, and discusses some of the special problems that DGPS applies to large space stations.
