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.
