| 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. |
