摘要:

分析了GPS弱信号的特点,探讨了只存在NLOS型信号时影响GPS定位的主要技术因素。以u-blox公司的LEA-5S为基础,设计和验证了针对弱信号环境下车辆定位的HSGPS接收机。最后,通过测试其启动的TTFF和定位准确度,论证了HSGPS接收机设计及弱信号环境下定位车辆应用的可行性。

关键词: GPS弱信号, 非视距传播(NLOS), 高灵敏度GPS(HSGPS), 首次启动时间(TTFF), 定位准确度

Abstract:

This article analyzes first the characteristics of severely degraded GPS signal,and discusses the main technical factors that affect GPS positioning when only NLOS signal exists.Then,the paper introduces the design and verification of HSGPS receiver bases on LEA-5S from u-blox for vehicle positioning under severely degraded GPS environment.And finally,it proves the feasibility of the novel HSGPS receiver design and the application of positioning vehicle under ultra weak GPS signal environment as well by means of testing the start-up TTFF and positioning accuracy.

Key words: severely degraded GPS signal;NLOS;HSGPS;TTFF;positioning accuracy
