In this paper, a novel backtracking scheme is investigated to shorten the time of the attitude determination-based initial alignment. Based on the investigated backtracking scheme, the recorded data during the forward process is reversed and connected with the forward data, which is further used to construct the vector observations for the attitude determination based initial alignment. The investigated...
Accelerometer is one of the most important units in inertial navigation system. Its mathematical model is established, and its output equation is derived. Reconstructing acceleration signal in frequency-domain is adopted in order to reduce the integration error in inertial navigation position calculation. To restrain the Gibbs phenomenon in the reconstruction of acceleration signal, a new method is...
