Abstract

The present invention provides methods, systems, and devices for determining a location for performing enhanced location-based trilateration, including: receiving location information (e.g., waypoints) from one or more external devices; validity of the positioning information; performing a normalization operation to normalize the received positioning information; assigning an overall ranking and a device-specific ranking to the positioning information; and assigning the verified and normalized Positioning information is stored in memory. The enhanced position-based trilateration may also include: selecting four positions (e.g., waypoints) from the memory based on a combination of the overall ranking and the device-specific ranking; The four waypoints are applied to the result of the Kalman filter to generate the final positioning value or waypoint. The output of the Kalman filter may also be reported and / or used as the current location of the device.
