Abstract
A method for improving position beacon tracking using spatial probabilities is provided. A beacon identity recognition device receives a central probability file from a remote data processing system to form a local probability file. The device receives a current position beacon identity. The device compares current position beacon identity to a previous beacon identity stored in the local probability file to form a comparison. The device determines if the current position beacon identity is valid based on the comparison. The device transmits a valid position beacon identity to the remote data processing system. The device updates the local probability file and then combines a weighted version of the local probability file with a new copy of the probability file from the remote data processing system to form a combined probability file. The combined probability file is then sent to the remote data processing system and replaces the existing probability file.
