A Federated Kalman Filtering Data Fusion Algorithm for Beidou/CDMA Navigation System
Bo Liu · Journal of Logistical Engineering University · 2009
The combined navigation system of combination with Beidou satellite and CDMA wireless network orientation can be applied to the military affairs and civil fields,and how to apply data fusion in efficiency in this system is the key of improving the positional accuracy.To focus on the characters of this system,this paper proposes one kind of Beidou/CDMA navigation algorithm based on the federation Kalman filtering.The algorithm builds state equation for both of the orientation systems respectively by using current statistical model of moving target,which can raise the positional accuracy after dealing with the allocation parameter in the way of wave filtering.
