Abstract:

Under the cooperation of multiairborne, the precise of relative position between twoairborne is the basic of cooperation work. This paper presents a kind of dynamic accuracy positioning algorithm by the inertia navigation information and accuracy relative range information between two airborne. Firstly, the relative ranging measurement and the inertia navigation information are combined to modify the relative error of inertia navigation systems for improving the accuracy of relative positioning. Then the relative ranging measurement is also employed to achieve the detection of the relative maneuvering state. Based on the results of maneuvering detection, the corresponding state model is chosen to provide the dynamic positioning between two airbornes. The simulation results show the good performance of the algorithm in the position accuracy and computation stability.
