In the polar regions, the local geographic frame will become invalid due to the convergence of meridians and other reasons. In response to this problem, the inertial navigation algorithm was reorganized in the transversal frame, and the error equation was also analyzed. The simulation experiment and actual experiment are carried out to verify the effectiveness of the inertial navigation algorithm in the transversal frame based on the single-axis rotation modulation inertial navigation system. Experimental results show that the transversal INS mechanization based on single-axis rotation modulation can solve the computational problems caused by the convergence of meridians in polar regions, achieving high-precision navigation.
