Appl. No.:

14/157305

Inventors:

- San Diego CA, US
Wyatt Thomas RILEY - Chesterbrook PA, US
Yuhua HU - Sunnyvale CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

G01C 21/00

Abstract:

Navigation solutions for a pedestrian or vehicle user are obtained by determining whether the direction and location of the user obtained from a map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, and if the direction and location of the user obtained from the map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, computing the navigation solutions based, at least in part, on the direction and location of the user.
