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...
The integrated navigation Kalman filter of strapdown inertial navigation system/Global Positioning System/star sensor (SINS/GPS/SS) with pesudorange and quaternion as observation information, has been researched for space autonomous navigation. To improve the real-time working performance, the reduced-order Kalman filter based state decoupling is put forward. With the hypothesis that SS precision...
Space transfer vehicle (STV), which performs missions such as servicing, repairing and rescuing in space without the ground tracking or communication, creates the requirement for the development of an autonomous navigation capability. The navigation sensors should have autonomous characteristics. Strapdown inertial navigation system (SINS), Global Positioning System (GPS) and star sensors (SS) are...
