Abstract
A hardware platform of an strap-down inertial navigation system is designed which is composed of low-cost MEMS based inertial sensors.An experimental study of SINS/GPS integrated navigation system is carried out based on this hardware platform.The result of this experiment show that the precision of this system is higher than the pure INS
and it is close to precision of GPS
and it meet the requirement.The attitude algorithm for SINS which based on MEMS is given and it is verified by experiment.
