Abstract:
In order to meet the requirements of autonomous navigation for aircrafts,a low-cost FOG-SINS/Doppler/Baro-altimeter integrated navigation system is designed and the digital simulation theory is introduced in detail.By comparing the digital simulation and running test results of aircrafts on bend flight line with straight flight line,the main factors that influence the navigation system are gained.Theoretical analysis and tests indicate that the designed navigation system can enhance the precision of SINS and highly restrain the current of the position error from divergence as the time accumulates.
