| 摘 要： | 为了满足飞机完全自主导航的需求,提出了一种低成本的光纤捷联惯导/多普勒雷达/气压高度表组合导航系统方案,探讨了该方案的数字仿真原理。通过对比飞机拐弯时机动飞行与直线飞行2种情况下的数字仿真和实际的跑车试验结果,得出了影响该组合导航系统精度的主要因素。理论分析和试验表明:该方案提高了捷联惯导的导航精度,明显抑制了惯导位置误差随时间积累而增大的趋势。

| 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 an... |
