摘要： Method and apparatus for locating position of a remote receiver is described. In one example, long term satellite tracking data is obtained at a remote receiver. Satellite positioning system (SPS) satellites are detected. Pseudoranges are determined from the remote receiver to the detected SPS satellites. Position of the remote receiver is computed using the pseudoranges and the long term satellite tracking data. SPS satellites may be detected using at least one of acquisition assistance data computed using a previously computed position and a blind search. Use of long term satellite tracking data obviates the need for the remote receiver to decode ephemeris from the satellites. In addition, position of the remote receiver is computed without obtaining an initial position estimate from a server or network.

摘要： Method and apparatus for managing a network element in a satellite navigation data distribution system is described. In one example, a network element includes a processor for processing satellite navigation data. For example, a network element may be a reference station, a hub, or a server in the satellite navigation data distribution system. The network element includes a memory for maintaining status variables associated with the processing of the satellite navigation data. The status variables may relate to the integrity of the satellite navigation data. The network element further includes a management agent for monitoring states of the status variables and communicating with a network management system to exchange information related to the states of the status variables. In one example, the management agent is configured to communicate using a simple network management protocol (SNMP).

摘要： Method and apparatus for processing location service messages in a satellite position location system is described. In one example, a mobile receiver includes a satellite signal receiver, wireless circuitry, and at least one module. The satellite signal receiver is configured to receive satellite positioning system signals, such as Global Positioning System (GPS) signals. The wireless circuitry is configured to communicate location service messages between the mobile receiver and a server through a cellular communication network. The location service messages may include any type of data related to A-GPS operation, such as assistance data, position data, request and response data, and the like. The at least one module is configured to provide a user-plane interface and a control-plane interface between the satellite signal receiver and the wireless transceiver. The at least one module is capable of processing location service messages communicated using either the control-plane signaling or user-plane signaling mechanisms.

摘要： A method and apparatus for distributing satellite navigation data is described. In one example, satellite signals are processed at each of a plurality of reference stations to receive a respective plurality of satellite navigation data streams. Packets are formed in response to said plurality of satellite navigation data streams to generate a plurality of packetized satellite navigation data streams. The packetized satellite navigation data streams are sent to a processing system. The processing system removes duplicate packets within said plurality of packetized satellite navigation data streams to generate a combined packet system. The combined packet stream is then sent into a communication network.

摘要： A method and apparatus for tagging digital photographs with geographic location data is described. In one example, a digital camera includes an imaging unit, a radio frequency/intermediate frequency (RF/IF) front end, and a memory. The imaging unit is configured to generate digital photographs. The RF/IF front end is configured to receive satellite positioning system signals and generate digital samples therefrom. The memory is configured to store a set of digital samples generated by the RF/IF front end with each digital photograph generated by the imaging unit. The digital samples produced by the RF/IF front end may be intermediate frequency samples and may include both in-phase samples and quandrature samples. Notably, the memory stores digital samples of GPS signals, rather than location data. The digital GPS samples may be processed by an off-line processing unit, such as a computer, to produce location data.
