METHOD AND/OR SYSTEM FOR SELECTIVE APPLICATION OF DIRECTION OF TRAVEL

摘要

Described are a system, method and apparatus for computing a navigation solution. In a particular implementation, a direction of travel (DOT) indicator or vector may be applied to augment computation of the navigation solution. The DOT indicator or vector may be selectively applied in the computation of the navigation solution based, at least in part, on an assessment of reliability of the DOT indicator or vector.

主权项

1. A method, at a mobile device, comprising:
obtaining a direction of travel (DOT) indicator or vector; and combining measurements to compute a navigation solution, wherein combining said measurements further comprises selectively applying said DOT indicator or vector in computing said navigation solution based, at least in part, on an assessment of reliability of said DOT indicator or vector.
