Abstract

The around orbit parameters and small body physical parameters determination methods are studied based on Square Root Information Filter (SRIF). Due to a great deal of parameters to be estimated and the complexity of the dynamics, the SRIF is designed to process the integrated navigation data and estimate the gravity field, rotation, and ephemeris of small body and orbit parameters of probe. The mathematic simulation experiments using the measuring data of Eros433 small body have validated the algorithm.
