A system and method for determining the locations of freight containers in a freight yard is described. A remote unit that includes a GPS receiver is attached to the freight containers. The remote receivers have an independent power supply-a battery. Intermittently, either by a timer or by a motion detector, the remote receivers are operated. During operation, the remote receivers receive signals from the global positioning satellite system and at an allotted time, transmit the GPS data to a base station before shutting down to conserve power. The base station processes the GPS data to determine a position in the freight yard of each freight container. When a particular freight container or contents is desired, a data base in the base station can be consulted and the contents and location of a particular freight container located. The freight yard is typically outside with a view of the GPS constellation, such as a rail yard, airport baggage area, ship yard, truck park, etc. An alternative is described for use where the freight yard is a warehouse and the satellite view is obstructed. The alternative uses psuedolites or repeaters to track freight containers within the warehouse.

The present invention is directed to the remote control of locomotives, and more particularly to various methods and apparatus employed in implementing systems for such remote control. Contemplated in the present invention are systems and methods for not only reliable remote-control communications, but also the use of repeaters and communications servers to assure reliable, centralized communication between locomotives and operator control units. In another embodiment, there is described a reliable distributed communication mode using an uncorrelated time sequence that does not interfere with a time division multiple access network. Differentiation between the centralized mode and the distributed mode is accomplished by assessing whether a locomotive and control unit is within a rail yard's infrastructure. Moreover, reliability is assured using a coordination server that dynamically routes packets between multiple satellite RCL repeaters based on received signal strength. Lastly, the present invention further contemplates the use of an out-of-band transmission to upgrade and test operator control units, thereby allowing for field maintenance and software upgrades.
