dc.description.abstract | This paper proposes new coning mitigation algorithm based on the signal processing technique.
For accurate attitude calculation of inertial navigation system, the coning error mitigation is a key part of attitude computation. Many researchers have used gyro outputs to calculate higher-order correction terms. But these results have a performance limit because they assume the signals to be polynomials. The proposed algorithm detects and estimates the sinusoidal components from gyro measurements. If coning signals occur in gyro measurements, a sinusoidal signal can be estimated using adaptive notch filtering, and higher-order correction terms can be calculated from parameters of this estimated signal. The proposed algorithm can properly operate on a vehicle with continuous and steady oscillations. Simulation results show that the direct compensation algorithm worked efffectively. | en |
