Abstract :
In this paper we investigate the performance of DGPS used for an Automatic Vehicle Location (AVL), in 2-D and 3-D navigation mode. The results obtained were treated statistically to determine the differential performance of these modes, which permit us to choose the appropriate mode for our application, such as the success rate during which it is possible to make differential corrections. Forcing the reference station to use the same satellite used by the mobile one in real time has improved significantly the performance of the system in the two modes of navigation. A conclusion has been arrived at which permits us to choose the appropriate mode of navigation satisfying our application
