  • Patent number: 11743678
    Abstract: The present invention provides a signal fusion system that is a probabilistic system fusing an arbitrary combination of heterogeneous signals for determining the location of electronic devices. The system includes a signal sampling device for detecting one or more signals emitted by an electronic device to be located, including geolocation signals, WiFi signals, Bluetooth signals, 4G communication signals, 5G communication signals, geomagnetism signals, or inertial navigation system signals (INS). A likelihood processor cooperates with the signal sampling device to receive information about selected sampled signals, and creates a grid of reference points for an interested area in which the electronic device may be located. The likelihood processor independently computes, for each selected sampled signal, a location likelihood that is a probability of observing the sampled signal given that the electronic device is located at different reference points in the grid.
