The Initial Alignment of SINS Based on Neural Network

摘要

Strap-down Inertial Navigation System (SINS) is the development direction of the inertial navigation technology. Its working precision based not only on the inertial measurement units, but also on the initial alignment. This paper uses the N-Tupple neural network in their research, gives principal algorithm and the training algorithm of N-Tupple, and the computer simulation is done. The simulation shows that, the alignment precision of the neural network method is higher than the normal methods, and the greatly reduced alignment time shows the advantage of the new method.
