A system and method for tracking the identity and position of an object. The system includes at least one locator unit the is attached to the object to be tracked. The system also includes at least one display unit carried by or with a user. The locator unit obtains its satellite position data from a satellite positioning system such as GPS, GLONASS, GALILEO, or the like, or position data from a radio positioning system such as LORAN. The locator unit then measures local position data with one or more sensors such as accelerometers and compasses and augments the satellite position data with the local position data. The locator unit transmits the combined position data to a display unit. The display unit calculates its own position in the same way and outputs the combined position of the locator unit relative to the augmented position of the display unit via a user interface.
