Abstract

Techniques and mechanisms for providing information to represent a course traversed by a mobile device. In an embodiment, navigation logic of the mobile device determines context data other than any geodetic data that specifies a position of the mobile device. With such context data, the navigation logic determines a sequence of estimates each for a respective position of the device on a course traversed by the mobile device. In another embodiment, determining the sequence of estimates includes determining a first estimate of a first position of the mobile device independent of any geodetic data that specifies the first position. Course information representing such a determined sequence includes timestamp information for the first estimate.
