Computer simulation results show that, the precision and fault tolerance of the integrated navigation system are improved greatly, compared with the pure GFSINS.
It is very important to apply rotation vector algorithm to the GFSINS that how to attain the relative angular displacement and meet its precision and updating frequency.
