Abstract :
For the applications of aircrafts work in collaboration, the initial relative position of multi-aircrafts is significant. A new method, achieved the relative position of aircrafts, is presented. Firstly, the multiple hypothesis is established, based on the error model of INS, to estimate the relative error covariance matrix between Inertial Navigation System(INS) information of multi-aircrafts, which is necessary for the least-square estimate method. Then the different least-square estimate results of the relative position between aircrafts can be obtained under each hypothesis. Finally, the weighted estimate results can be acquired according to the Bayes´s formula. Simulation results show the stabilization and the precision of this algorithm in the relative position.
