Abstract

Facing the probable situation of less four navigation satellites of Global Positioning System (GPS) during the orbit transferring of Space Transfer Vehicle (STV), the integrated navigation plan from three satellites pesudorange information is supposed and the performance of GPS/Strapdown Inertial Navigation System (SINS) based three GPS satellites is discussed. We construct the SINS space navigation model, derive the navigation errors model of SINS and chose the errors as the states of Kalman filter. The corresponding Kalman filter with three pesudorange information is designed. Simulations show that GPS/INS could still supplies better navigation parameters for STV in orbit transferring just with 3 GPS navigation satellites.
