1. A computer implemented method for improving position beacon tracking using spatial probabilities, the computer implemented method comprising: receiving a copy of a central probability file from a remote data processing system to form a local probability file; receiving a current position beacon identity; comparing the current position beacon identity to a previous position beacon identity stored in the local probability file to form a comparison; determining if the current position beacon identity is valid based on the comparison; updating the local probability file to form an updated local probability file; receiving a new copy of the central probability file; combining the updated local probability file with the new copy of the central probability file to form a updated central probability file; and transmitting the updated central probability file to the remote data processing system.
