Patent ID: 7154436

Claim:
A Global Positioning System (GPS) receiver for determining geolocation from at least one GPS satellite, the GPS receiver being capable of receiving a GPS signal comprising a spread spectrum radio frequency signal, the GPS receiver comprising: a downconverter section for converting time spread spectrum radio frequency signals from a transmitted frequency to a lower frequency; and a processor section, for processing the lower frequency signals to determine the geolocation of the GPS receiver, wherein at least one of the downconverter section and the processor section utilizes circuitry that is shared between the GPS signal and a Local Area Network (LAN) frequency signal that carries an augmentation to the GPS receiver and the geolocation of the GPS receiver is determined with the lower frequency signal obtained from the GPS signal received from a GPS satellite along with the augmentation when the GPS receiver is unable to acquire sufficient numbers of GPS satellites to determine time geolocation of the OPS receiver.
