Abstract

Gyro-free inertial measurement technology utilizes an array of accelerometers to replace traditional gyroscopes for measuring the attitude of a carrier. By synthesizing existing literature, this paper summarizes the research on gyro-free strapdown inertial measurement technology. It conducts comparative analysis on two aspects: different accelerometer configurations and algorithms for calculating angular velocity. The advantages and disadvantages of corresponding configurations and solution methods are summarized. Finally, future research directions are discussed.
