Title:
RECOVERY FROM POSITION OUTLIER AND TIME OUTLIER IN POSITIONING
Document Type and Number:
Japanese Patent JP2016156837
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a mobile device which may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix.SOLUTION: In some implementations, an outlier detector compares a computed position fix to an element of assistance data to generate an outlier likelihood. A decision to perform a recovery operation may be made based, at least in part, on the generated outlier likelihood. In some implementations, a computed reliability of the position fix may also be considered in making a recovery decision.SELECTED DRAWING: Figure 3
