    摘要: Equipment and a method by which power consumed by a ranging receiver (12) is reduced without appreciably impairing performance of the GPS receiver (12), the method including: a step (21) in which a controller (15) reads sensor signals provided by a motion sensor (14) mechanically coupled to the ranging receiver (12); and a step (22) in which the controller (15) powers down selected components of the ranging receiver (12) based on whether the sensor signals indicate only at most insubstantial motion of the ranging receiver (12). The motion sensor is advantageously a motion sensor constructed using MEMS technology, but at any rate is of a type using so little power as to provide a power savings when used according to the invention, i.e. when it is always on and at least partially based on its sensor signals, the ranging receiver (12) is sometimes at least partially turned off.

    摘要: A system and method for changing the weighting accelerometer filtering based upon motion sensor measurements. Using measurements from motion sensors, one or more features can be extracted. This information is used by an algorithm to assign a most appropriate test feature class to be the class of the state of motion at a particular moment in time. This information is used to provide more accurate positioning information, and can also be used to power down the motion sensor at various times, providing an improvement in battery efficiency.
