Abstract

For the special movement of smart munitions, the improvement of TCR's attitude detection accuracy by means of highprecision inertial attitude algorithms was researched. The traditional rotation vector algorithm was modified by using a precise integration of angular increment. The result of simulation shows that the precision of the modified algorithm is superior. Useful recommendations have been made for engineering research of the module with detection of full attitude based on MEMS rate gyroscope.

Key words： trajectory correction; attitude algorithm; rotation vector; rate gyroscope
