Gyros-free inertial measurement unit

WANG Jinsong, WANG Qi, SUN Shenghe(Dept of Automation Test and Control,Harbin Institute of Technology,Harbin 150001,China)  
The characteristics and classifies of inertial measurement unit and micro inertial measurement unit are briefly introduced and the predominance of micro inertial measurement unit based on the design of gyrosfree technique is pointed out.The developing state of gyrosfree measurement technology at broad and home is also reported and a novel structure design is put forward.The calculation method of navigational equation optimizes the calculation method using sensors redundant information and reduces the accumulative error of the solutions of differential equations and increases the navigation accuracy of gyrosfree micro inertial measurement unit and then simulating calculation is carried out and the practicable verification of this scheme is tested.
