13. A method of deriving a location of a satellite positioning receiver, the method comprising:
-
receiving a plurality of positioning signals at a GPS RF receiver; selectively switching between a plurality of functions performable by a multi-function portion of the satellite positioning receiver that include an engine, tracker, or sensor function, where each function is enabled to process the positioning signals, wherein selectively switching includes switching by default to an active mode whenever the satellite positioning receiver is powered up or reset, and also includes determining whether an event that requires changing the operating mode or the function of the multi-function portion has occurred; configuring the multi-function portion of the satellite positioning receiver according to the function selected; and processing in the multi-function portion at least one of the plurality of positioning signals resulting in a type of positioning data. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
