Position source selection
First Claim
1. A navigation device, comprising:
- a memory operable to store an application;
a satellite navigation receiver operable to receive signals from a first position source;
a communications module operable to receive signals from a second position source; and
a position subsystem in communication with the memory, satellite navigation receiver, and the communications module, the position subsystem operable to;
identify movement of the navigation device;
select one of the position sources based upon the identified movement;
determine position using the selected one of the position sources; and
communicate the determined position to an application stored in memory to perform a position dependent function.

Abstract
Techniques are described for position source selection. In an implementation, an electronic device provides a variety of functionality including at least functionality to determine position. The electronic device may be further configured to select between a plurality of position sources to determine position based upon a variety of selection criteria. In an implementation, a last known position may be stored when position is being determined through the plurality of position sources. The last known position may be used as an alternative to determining position via the position sources when one or more of the position sources are unavailable. In another implementation, the last known position may be employed to automatically select one of the plurality of position sources to be used by the electronic device for determining position.
