Estimating the term…
Embodiments of the invention involve providing assistance data to a global position and navigation receiver, for example topographical data, such that the receiver can decide on a specific action depending on that data. The topographical data may include one or both of geographical data and architectural data. Geographical data may include information about natural formations, such as hills, valleys, forests, etc. Architectural data may include manmade formations, such as streets, buildings, bridges, etc. The receiver may then interpret and decide on a course of action for controlling the receiver base on the assistance data.
An apparatus for a receiver having circuitry configured to receive signals from at least one source providing global positioning information, the apparatus comprising a receiver controller configured to compare an estimated position of the at least one source providing global positioning information with topographical data to determine whether a topographical feature defined in the topographical data would block receipt of the signals from the at least one source by the receiver and to modify navigational instructions provided by the receiver to a user to guide the user on a path that is less affected by a topographical feature that has been determined to block receipt of the signals.
A method to use in a receiver having circuitry configured to receive signals from at least one source providing global positioning information, the method comprising:
A system for a receiver having circuitry configured to receive signals from at least one source providing global positioning information, the system comprising:
