Abstract:
A position fix of a mobile device is computed based, at least in part, on a plurality of data items. A metric that is indicative of a reliability of the position fix may be generated based, at least in part, on a number of independent ones of the data items and/or an indication of reliability of at least one of the data items. In at least one implementation, the plurality of data items may include SPS satellite signals and/or pseudoranges and an externally obtained position.
