1. An apparatus comprising:
- a controller operatively enabled to cause position locating circuitry to switch from a first mode to a second mode at least partially in response to at least one mode-switching test being satisfied, wherein said at least one mode-switching test is at least partially satisfied in response to detection of at least one non-timed test condition, said at least one non-timed test condition comprising at least a first test condition under which wireless signals greater than or equal to a first threshold signal strength have been acquired from a first set of space vehicles (SVs),wherein said position locating circuitry acquires wireless signals associated with a satellite positioning system (SPS) in the first mode, and acquires said wireless signals less often than during the first mode in the second mode.

Abstract
Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switching test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled.
