Relative GPS

The purpose of this research is to investigate the relative accuracy of GPS receivers as related to navigating a robotic vehicle in a caravan following mode and related applications. For most applications robotic vehicle navigation requires position accuracy less than a meter. The caravan following mode of robotic vehicle operation is of particular interest to the staff at Texas A&M University because of the parallel research effort with a Chrysler mini-van in the Texas A&M University BART project. The caravan following mode of navigation consists of a manned lead vehicle followed by an unmanned robotic vehicle that tracks the lead vehicle.<
