Abstract
In an embodiment, a method monitors, within a global navigation satellite system (GNSS) limited zone, an intra-zone location of a vehicle having a GNSS receiver, the intra-zone location being within the limited zone. The method determines a simulated intra-zone location of the vehicle based on the intra-zone location monitored to calculate a likely location of the vehicle. The method calculates a global location of the vehicle based on the intra-zone location and the location of the GNSS limited zone within a global network of limited zones. The method broadcasts, from a transmitter within the GNSS limited zone, a GNSS signal representing the global location of the vehicle.
