A personal location device with transmit capa- bilities, such as a GPS receiver incorporated in a paging transceiver, can triangulate its position using GPS satellite transmissions and transmit the posi- tion coordinates to a paging system. This allows the paging system to track the location and movement of the user of the portable transceiver. If a user of one of these transceivers requires help, an emer- gency signal can be transmitted to the paging sys- tem upon the user pushing a button. This emer- gency signal will also contain the current location coordinates of the user. This allows an operator at the paging system to guide help towards the user. The transceiver continues to transmit it's location coordinates so that the operator has the most cur- rent location of the person in need of help. Under ideal conditions this locator system works well.
