<p>A GPS gate system is described for triggering transmission of a message. The system may include a GPS receiver determining a location of the GPS receiver based upon signals received from a GPS satellite system. The GPS receiver determines if the GPS receiver has passed through a GPS gate based upon the received signals. The GPS system may further include a communications system to connect the GPS receiver with a GPS gate communications system to receiver a message generated by the GPS receiver based upon the crossed GPS gate.</p>
