Abstract
Aiming at the problems of single navigation information type,low positioning accuracy,weak anti-interference capability,and obvious positioning drift of traditional GPS positioning devices,this paper designs a multi-GNSS anti-interference high-precision positioning device.Firstly,multi-GNSS receivers are used to receive navigation information from different constellation combinations simultaneously.Secondly,by increasing the number of receiving channels,multiple types of satellite navigation data are compared and calculated to filter out abnormal data generated by malicious interference.Finally,effective data are fused and processed to improve positioning accuracy and stability.Continuous data collection is performed for more than 40 000 times in the outdoor environment.The results show that,compared with the traditional single GPS receiver design,the positioning stability is significantly improved,and stable positioning is maintained even in special environments where any system is interfered with or fails.The experiment proves that the design has the advantages of strong anti-interference,high precision,and good stability.关键词
