POSITION DETERMINATION SYSTEM AND METHOD
First Claim
Patent Images
1. A system for controlling an electronic device comprising:
- a processor;
a first position determining component coupled with said processor, wherein said first position determining component is a GNSS receiver configured to provide GNSS positioning information; and
a second position determining component coupled with said processor, wherein said second position determining component provides terrestrial positioning information derived from at least one terrestrial broadcast signal if said first position determining component fails to determine an acceptable GNSS position fix of said electronic device in at least two dimensions.

Abstract
An improved position determination system and method are described. The method includes determining that a failure to generate an acceptable GNSS position fix has occurred. In response to determining that the failure to generate an acceptable GNSS position fix has occurred, terrestrial positioning information is accessed which is derived from at least one broadcast signal. A second position fix based upon the terrestrial positioning information is generated.

11. A method for controlling an electronic device comprising:
-
determining that a failure to generate an acceptable GNSS position fix has occurred, deriving terrestrial positioning information from at least one broadcast signal in response to said determining; sending the terrestrial positioning information to a location server which uses the terrestrial positioning information to determine a terrestrial position fix; and using said terrestrial position fix to determine a geographic position of said electronic device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
