Abstract
Two problems of conventional attitude algorithm in MEMS rotary SINS are focused on in this paper. One is that the yaw error diverges, and the other is that the highresolution rotary encoder is relied on. In order to solve the problems mentioned, an improved attitude algorithm in MEMS-RSINS aided by compass/rotary encoder is proposed and detailed. Then simulation is conducted to prove the validity of this improved attitude algorithm.
