Abstract

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 proposed which retains original length of block-process data and is convenient to be integrated. The method is proved to have higher precision than the conventionally used 3-sample algorithm by digital simulation experiment.
