1. A tracking system comprising:
- a first mobile device comprising a first position determining apparatus;
a second mobile device comprising a second position determining apparatus; and
a central monitoring system for monitoring the positions of the first and second mobile devices,wherein the first mobile device is capable of transmitting to the central monitoring system first position information associated with the first mobile device and relaying to the central monitoring system second position information associated with the second mobile device and switching a mode of operation of the first mobile device such that the first mobile device transmits the first position information to at least a one of the second mobile device and a third mobile device for relaying to the central monitoring system.
