    摘要： A system within a multi-channel GPS receiver that searches for Global Positioning System (GPS) satellites by receipt of a plurality of GPS signals where each GPS signal corresponds to a GPS satellite having a GPS satellite identification number (ID) is shown. The system may include a controller in control of the multi-channel GPS receiver that assigns each GPS satellite ID that corresponds to each of the plurality of GPS signals received by the multi-channel GPS receiver to an individual channel of the multi-channel GPS receiver and a monitoring channel selected by the controller from the multi-channel GPS receiver that monitors the received GPS signal.

    摘要： A multipath component in a GPS signal received is detected when an asymmetry exists in the correlation function of the received signal and the expected GPS signal. The multi-path component is also detected, even without a line-of-sight component in the received GPS signal, when a peak of the correlation function jumps a significant distance (i.e., a sudden, significant change in a detected code phase).

    摘要： A wireless communications device comprises a communication receiver and a positioning system receiver in the wireless mobile communication device. An absolute time signal is received at the positioning system. A network time signal is received at the communication receiver of the wireless mobile communication device. A controller is in signal communication with the position system receiver and the communication receiver. The controller is configured to determine an offset of the absolute time signal from the network time signal and generates a timing mark. The timing mark is tagged by the positioning system receiver with an internal clock value wherein the timing mark has a known relationship with the absolute time signal. A memory stores the offset of the absolute time signal from the network time signal. A transmitter in the wireless mobile communication device transmits the offset for receipt by another wireless mobile communication device.
