Hardware in the loop simulation is an effective way to test the performance of satellite navigation receiver in high rotating external ballistic environment.In order to test the performance of the satellite navigation receiver under the high spin environment conditions,the working principle of the two-dimensional trajectory correction fuze and the basic principle of the Beidou satellite navigation receiver are expounded.A high spin 7 degree of freedom ballistic model is set up.The simulation model is written and running on the RT-LAB real time simulation platform.The hardware in the loop simulation test of satellite navigation receiver is carried out under non rotating conditions and rotation conditions respectively.The simulation results show that the data of the simulator coincide with the data curve after the conversion.Experiments show that the hardware in the loop simulation system can effectively test the function and accuracy of the high rotation rocket＇s satellite navigation receiver.
