1. A pager comprising:

  • a global positioning system receiver;

    a transceiver coupled to said receiver to transmit global positioning coordinates of the receiver, said transceiver being operable to automatically transmit said coordinates when a request for the coordinates is received;

    an event generator coupled to said transceiver, said event generator to track the global positioning coordinates of said receiver such that when said tracked global positioning coordinates deviate from a set of preprogrammed coordinates said deviated coordinates are automatically transmitted by said transceiver;

    a power down device that transitions said pager into a sleep mode when a battery is low, said pager periodically awakening from said sleep mode to automatically transmit said global positioning coordinates of said receiver; and

    a user selectable panic operator, such that once the operator is operated, said transceiver automatically sends a message indicating that help is needed and including the coordinates of the global positioning system receiver.
