Multi-stage dead reckoning for crowd sourcing
A device identifies signals it receives at a particular point in time, such as Wi-Fi signals and cell tower signals. The device records data indicating these identified signals, as well as data used to determine the position of the device at that particular point in time. The position of the device...

| description | A device identifies signals it receives at a particular point in time, such as Wi-Fi signals and cell tower signals. The device records data indicating these identified signals, as well as data used to determine the position of the device at that particular point in time. The position of the device is determined using dead reckoning, which is separated into two stages. In the first stage, a distance and direction of movement is determined at the device based on data from various inertial sensors of the device. In the second stage, various filters, maps, and/or other techniques are used at another device (e.g., a crowd sourcing data service) thus alleviating the device of the burden of performing the second stage. |
