Techniques for reporting on or tracking ground vehicles

摘要

Ground vehicle reporting and tracking techniques are provided to track vehicles associated with a particular area (e.g., an airport, a military base, etc.). Ground vehicles may regularly report information about the vehicle to one or more control stations via corresponding communication links. The communication links may include, for example, an Automatic Dependent Surveillance-Broadcast (ADS-B) link and a non-ADS-B link.

1. An apparatus comprising:
a position estimator to track a current position of a vehicle; a vehicle Automatic Dependent Surveillance-Broadcast (ADS-B) transmitter to wirelessly transmit vehicle information associated with the vehicle, wherein the vehicle ADS-B transmitter is to disable the transmission of the vehicle information based at least in part on the current position of the vehicle with respect to a surface region; and an ADS-B link augmentation system (ALAS) transmitter to transmit the vehicle information to a remote user control station via a non-ADS-B communications protocol responsive to an output signal from a geographic switch to monitor the vehicle position with respect to the surface region.
