Abstract :
Multiscale recursive estimation is the algorithm of multisensor system based on the scale, which uses the multiscale error model correcting the state estimation on the coarse scale and gets the optimal estimation based on overall observations on the finest scale. The algorithm is used in SINS/GPS integrated navigation system. The estimates are more accurate than the results at the finest scale. The simulation results show that the accuracy is improved.
