Abstract
A client device maintains location state data including a first location estimate of a geographic location of the client device. The first location estimate is based on a first motion measurement obtained over a first time period. The client device retrieves a second motion measurement obtained over a second time period subsequent to the first time period and uses it and the first location estimate to generate a second location estimate. The client device sends the second location estimate to a server. The server further processes the second location estimate to generate an updated second location estimate. The client device retrieves a third motion measurement and generates a third location estimate. The client device receives the updated second location estimate and uses it to adjust the third location estimate. A fourth location estimate is generated using the adjusted third location estimate.
