RECOVERY FROM POSITION AND TIME OUTLIERS IN POSITIONING

A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, a method may comprise checking a position fix of a SPS receiver for consistency with assistance data used to ge...

More Information
Summary:A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, a method may comprise checking a position fix of a SPS receiver for consistency with assistance data used to generate a position fix. The method may further comprise determining whether to generate a new position fix using less than all of the assistance data based, at least in part, on results of the checking of the position fix.
