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… More >
