Abstract: The “Vehicle Tracking System and Game” integrates a GPS navigation system with invention specific hardware and software. A user installs a mobile unit on his race vehicle which features software allowing a processor connected to the electronics of the user's vehicle to communicate with an inertial navigation system which collects racing information, with a remote database which features software for various interactive real-time or virtual GPS Racing Games and processing the racing information of all users, and with a GPS system in real time. The mobile unit collects, processes, saves and transmits user specific racing information continuously throughout the game. This racing information is data of racing performance parameters specific to the game subscribed for by the user. The database processes and evaluates the received racing information, offsets this information with the users' basic input data and compares the information of all users.
