Abstract :
For the navigation precision of traditional UAV radio position (RP) navigation system is low, the new kind of RP navigation method based on least square estimation is put forward and the model of RP navigation system is built. Taking the dead reckoning (DR) as the benchmark, the simulation model is established and the simulation calculation is made by Matlab/Simulink tool box. The simulation results show that the RP navigation system based on least square estimation can restrain nonlinear disturbance and this system has good navigation precision.
