Abstract

In order to reduce calculation amount and keep alignment precision of nonlinear alignment, the problems that the sample points are directly proportional to state dimension and the calculation amount is large in cubature Kalman filter (CKF), a new alignment algorithm with mixed filter based on simplified CKF (SCKF) and reduced dimension CKF(RDCKF) proposed. The level alignment finished by a large misalignment angle model and SCKF without coarse alignment; the fine alignment fulfilled by a large azimuth misalignment angle model and RDCKF based on the level alignment. The simulation result shows that this way two disadvantages that CKF's "dimension problem" and RDCKF's application limitation. It is available on any misalignment angle and has higher precision, and with important engineering application value.

Key words： large misalignment angle; initial alignment; reduced dimension CKF; simplified CKF
