Abstract :
In order to improve the convenience of installation and calibration of accelerometers, and to avoid the limitation of angular rate calculation in gyroscope free strapdown inertial navigation system (GFINS),a new scheme of gyroscope free inertial navigation system using 9 accelerometers is proposed. All 9 accelerometers are installed on three orthogonal axes, with orientations parallel to the three orthogonal axes respectively. Navigation principle and calculation procedure of the 9-accelerometer based GFINS is presented. Numerical simulations are carried out. Simulation results show that the design of scheme of GFINS is feasible and effective.
