摘要
介绍了一种采用输出校正方式DGPS/INS组合导航系统引导无人机下滑着陆的方案。给出了该方案的数学模型,对组合导航系统进行了数字仿真,并在数字仿真的基础上进行了动态跑车试验,验证了所设计的输出校正方式DGPS/INS组合导航系统能够满足引导无人机自动下滑着陆的精度要求。
In this paper, a hybrid DGPS / INS navigation system using output-correction Kalman filter is presented for the UAV approach and landing. The architecture and mathematical model of the hybrid navigation system is also presented. Numerical simulation and dynamic physical experiments using this output correction Kalman filter are made to validate the positioning precision of the DGPS/INS navigation system. The analysis and experiment results show that this hybrid DGPS/INS navigation system can conform to the requirements for UAV approach and landing.
