ABSTRACT = {Strapdown non-exchangeable error compensation technology in high dynamic 
environment is one of the key technologies of strapdown inertial navigation system. 
Mathematical platform is used in strapdown inertial navigation system instead of physical 
platform in traditional platform inertial navigation system, which improves reliability and 
reduces cost and volume of system. The maximum error source of attitude matrix 
solution is the non-exchangeable error of rotation due to the non-exchangeable of finite 
rotation of rigid bodies. The rotation non-exchangeable error reaches the maximum in 
coning motion, although it can be reduced by shortening the correction period and 
increasing the real-time calculation. The equivalent rotation vector method is used to 
modify the attitude to reduce the coning error in this paper. Simulation experiments show 
that the equivalent rotation vector method can effectively suppress the non-exchangeable
error and improve the accuracy of attitude calculation.},
