Abstract:	In order to support the German MOMS-2P mission on PRIRODA with orbit and attitude data a high precision navigation package called MOMSNAV is developed in contract to the German space agency (DARA). MOMS (Modular @tical Multispectral Scanner) together with MOMSNAV are scheduled to fly on-board the PRIRODA module of the space station MIR in 1995. The navigation package for DGPS orbit and inertial attitude determination consists of a spaceborne GPS receiver, a redundant high-precision gyro package, a data management system and a power control and distribution unit. It will provide in combination with GPS reference stations on earth a differential orbit accuracy of * 5 m and the relative attitude with + 10 ” accuracy. The GPS sensor unit is the high dynamics C/A-code Ll, dual antenna, 2x6 channel spaceborne GPS “SEASTAR” receiver manufactured by MOTOROLA Inc. providing carrier phase measurements. The gyro-system, which is manufactured by LITEF GmbH, uses two dynamically tuned gyros (DTG’s) in each gyro package. The paper describes the basic system and mission parameters and the detailed design of MOMSNAV. Special problems for the use of GPS on a large space platform with respect to shading and multipath are addressed.
