Abstract
The paper focuses on two problems of conventional attitude algorithm in MEMS rotary SINS. One is that the yaw error diverges, and the other is that the high-resolution 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.
