Six-accelerometers Configuration Scheme for SINS

Firsts it briefly describes the principle of gyroscope-free stapdown inertial navigation system, then a six-accelerometers configuration scheme in triangular prism shape is presented according to the characteristic of engineering appliance. Furthermore, the mechanical calibration equation is formulated, and a method, which improves the carrier's angular rate calculation precision, is proposed and analyzed. The simulation result shows that the proposed scheme is feasible.
