    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.
