Patent ID: 8793033

Claim:
A satellite signal acquisition apparatus comprising: a parking detector arranged to: analyse, when in use, self-mobility behaviour for monitoring mobility of a vehicle; detect a first mobility behaviour associated with parking in a building, wherein the detection of the first mobility behaviour comprises detecting a first predetermined event and a first predetermined corroborating event; and detect a second mobility behaviour associated with exiting the building subsequent to the first mobility behaviour; and a global navigation satellite system receiver operably coupled to the parking detector and arranged to acquire a satellite signal using predicted satellite orbit data in response to the detected first and second self-mobility behaviours; the apparatus further comprising at least one of: a light level measurement unit arranged to measure an ambient light level, wherein the first predetermined event comprises a change in the ambient light level by an amount equal to or greater than a predetermined value; and a speed calculator arranged to measure a speed, wherein the first predetermined corroborating event comprises a reduction in the speed to or below a predetermined speed.
