摘要
针对无人机在海上与陆上飞行环境的差异,建立了基于SINS/GPS的组合导航系统数学模型。通过故障模拟,对导航系统在GPS接收机失效工作状态下的性能进行了仿真,并由仿真结果验证了相应安控策略的可行性,无人机可飞至陆上进行伞降回收,具有工程参考价值。
Aim at the difference of UAV flying environment between the offshore and onshore,the math model is constructed based on SINS /GPS integrated navigation. The navigation performance is simulated in the condition of GPS failure,the results indicate the control strategy is correct,the UAV can be parachute recovered on land and have a great engineering application value.
