Design and Analysis of a Simple GPS Code Information-based Relative Positioning Assistant Algorithm

Many vehicle application services called LBS (Location based services) are currently based on location 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 communication satellites into similar environment respectively to calculate the relative position with a higher accuracy is proposed in this study.
