Abstract

Error rotating compensation method can effectively improve the long-time navigation accuracy. The rotation program of the turntable is an important factor to determine the precision of rotary strapdown inertial navigation system. By deriving the error model of strapdown inertial navigation system and analyzing the navigation propagating function, the mechanism of error rotating compensation is described in detail. And the propagation characteristics of inertial sensor error, scale factor error and installation error are also studied. Based on the dual-axis rotating strapdown inertial navigation system, a thirty-two sequence indexing scheme is put forward to modulate the inertial instrument errors better. The simulation results show that the thirty-two sequence dual-axis indexing scheme can effectively reduce the amplitude of the errors. And it has obvious advantages when compared with the sixteen sequence dual-axis indexing scheme.
