摘　　要：Many vehicle application services called LBS （Location based services） are currently based on loca- tion information, but civil location equipment is either too expensive or the positioning accuracy is not high enough to provide LBS. If each vehicle used as a center can precisely calculate the relative positions of other vehicles, LBS can be more easily provided. Based on this premise, a new method by limiting low-cost GPS receivers and commu- nication satellites into similar environment respectively to calculate the relative position with a higher accuracy is proposed in this study.
