Abstract: Method, systems and devices for determining for performing enhanced location based trilateration include receiving location information (e.g., waypoints) from one or more external devices, determining the validity of the received location information, performing normalization operations to normalize the received location information, assigning an overall ranking and a device-specific ranking to the location information, and storing the validated and normalized location information in memory. The enhanced location based trilateration may also include selecting four locations (e.g., waypoints) from the memory based on a combination of the overall ranking and the device-specific ranking, and generating a final location value or waypoint based on a result of applying the four selected waypoints to a kalman filter. The output of the kalman filter may also be reported and/or used as the device's current location.

Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device may include improved dead reckoning solutions in which the mobile device performs location determination calculations with the aid of network components or global positioning systems (GPS). The network aided location information may be provided to the processor and utilized in measuring the accuracy of sensor based location calculations. The mobile device may utilize local sensors to obtain a set of combined sensor output location information, which may seed execution of dead reckoning. To ensure that most accurate location information is provide to the enhanced location based service, the dead reckoning location information may be compared to a current best estimate. Results of the comparison may be passed to the enhanced location based service and the methods, systems, and devices may reiterate the location determination.

Abstract: Methods, devices and systems for generating enhanced location information on or about a mobile device. A mobile device may be configured to determine an initial location value, compute an initial location accuracy value, compare the initial location accuracy value to a threshold value, and establish a communications group with a plurality of transceivers in response to determining that the initial location accuracy value exceeds the threshold value. In response to establishing the communications group, the mobile device may receive location information from the transceivers, use the received location information to determine a trilateration position value, and compute a trilateration variance value. The mobile device may then determine a final location value based on a combination of the initial location value, initial location accuracy value, trilateration position value, and trilateration variance value, and use the final location value to provide an enhanced location based service.
