Abstract
Due to the small size of the INS for the rotary rocket system, a scheme that a FOG and a DTG are used as the angular rate sensor is put forward. With the scheme, the system is finished in the volume of Φμ190mm×180mm. Using the technology of rotating modulation, the influence of the low-accuracy DTG drifts are weakened. The simulation results show that the alignment error of the attitude angles is less than 0.02¡ã within 280s.
