Mobile Senor Registration Algorithm Based on Exact Method

Exact Method (EX) has been recently proposed to handle the dynamic sensor bias estimation based on the local track estimates at different times, which only apply to fixed platform sensors. On the basis of EX algorithm, an new algorithm is presented to derive the dynamic sensor bias estimation in networked 3-D mobile sensor system based on the local track estimates at different times, which is called MEX algorithm for short. To testify the correctness and validity of the proposed algorithm, the simulations were carried out. And the result shows that the MEX algorithm can effectively estimate sensor measurement biases and attitude angle biases.
