In order to improve the accuracy of calculation speed in MEMS INS system, a method using high-precision numerical integration algorithm to abstract the angle increment and the velocity increment of the system is presented. Putting these signals into the typical speed algorithm to compute, that is applicable to the traditional INS system. Compared with the existing methods, simulations showed that the new algorithm has higher accuracy and required less calculation. Therefore, it has a certain engineering value in practice.
