Claim One:
1. A position-tracking system for tracking the position of at least one mobile object comprising: a position-tracking device associated with the at least one mobile object such that the position-tracking device moves with the mobile object, wherein the position-tracking device includes at least one inertial sensor; a wireless aiding system associated with a first area; and a host computer system in wireless communication with the position-tracking device, wherein the system includes a high resolution operational mode and a wide area resolution operational mode, and wherein the system transitions between the high resolution operational mode to the wide area resolution operational mode when the mobile object moves between the first area, which requires high object location resolution, and a second area, which requires lesser object location resolution, and wherein the location of the at least one mobile object in the high resolution operational mode is determined based on at least a combination of input from the at least one inertial sensor and reference position signals from the wireless aiding system received by the position-tracking device.
