GPS-server.net -offers us raiders GPS-monitoring service. The service  allows tracking our voitures real time  on a map. Use of this service requires that you install an Apple or Android device tracking application that sends the location as a mobile data to the tracking server. Your mobile phone must therefore have access to data roaming. The data used by the tracking device is about 50 MB during the tour. Below you will find links to the service.
