摘要： Methods for provision of a sequence of timing signals for one or a plurality of microprocessors, microprocessor peripheral devices or other timing-controlled instruments ("users"), using timing signals determined from a Satellite Positioning System (SPS), such as GPS or GLONASS. In a first embodiment, one or a plurality of users is individually provided with SPS signal antennas and receiver/processors, and timing signals are optionally individually for each user. The timing signals can be periodic, for example, a One-Pulse-Per-Second signal for fine corrections of high frequency timing signals issued by an internal or external clock. The timing signals can also be substantially non-periodic. The timing signals may also be used to determine the time at which selected events occur, such as issuance of interrupt commands in, or directed to, a microprocessor. In another embodiment, CDMA or spread spectrum communications can be implemented and improved by using frequency hopping or other carrier-coded communications in which a time interval for use of the present carrier code is determined by two spaced apart timing signals received from an SPS timing device. In another embodiment, transmission times for each of a plurality of TDMA communications stations are synchronized using SPS timing signals. In another embodiment, each of a plurality of cellular telephone (CT) users is allocated to an appropriate CT cell for signal transmission and receipt, using timing and location information obtained from differential SPS signals.

摘要： A mobile device may be operable to collect location data for a RF node and cache the collected location data in the mobile device. Resources that may be utilized for improving the uploading of the cached location data to a location server may be determined by the mobile device. The cached location data may be communicated, to the location server for updating a location database, by the mobile device utilizing the determined resources. The mobile device may determine and utilize an opportunistic transport based on a data usage and/or an access. The mobile device may store a subset of the location database locally for comparing with the cached location data for redundancy. The compared location data may be transmitted by the mobile device to the location server for updating the location database if the compared location data are not redundant data.

摘要： A transmitting communication device may iteratively adjust its transmit power, and may estimate, based on iterative transmit power adjustment, relative location of a receiving communication device. The transmit power may be initialized to a maximum value, and the transmit power may be iteratively reduced until connectivity with the receiving communication device is lost. The loss of connectivity may be determined based on reception of responses to ping messages transmitted by the transmitting communication device. The transmitting communication device may authenticate the receiving communication device and/or a user of the receiving communication device. The authentication may comprises utilizing transmit power adjustment and/or relative location estimation therefrom to ensure that a separation between the devices does not exceed a maximum value. The transmitting communication device may generate location info associated with the receiving communication device based on the relative location estimation, and may communicate the location info to a location server.

摘要： A multi-standard single chip integrated within a multi-standard mobile device concurrently receives multi-standard radio frequency signals by corresponding two or more integrated radios. The multi-standard single chip generates full GNSS measurement comprising pseudo-range information using the received radio frequency signals. The multi-standard single chip comprises a GNSS radio and multiple non-GNSS radios such as Bluetooth. The full GNSS measurement is generated using GNSS radio frequency signals received by the integrated GNSS radio and communicated over, for example, Bluetooth radio. GNSS satellite reference information embedded in radio frequency signals received by the integrated non-GNSS radios is extracted to assist the full GNSS measurement. A full GNSS navigation solution for the multi-standard mobile device is generated internally to and/or externally to the multi-standard single chip depending on the location of a navigation engine. The generation of the full GNSS measurement is independent of a host processor within the multi-standard mobile device.

摘要： A global navigation satellite system (GNSS) enabled mobile device comprising a crystal oscillator and an automatic frequency correction (AFC) circuit may be operable to share the crystal oscillator between processing of cellular radio signals and processing of GNSS data messages. The GNSS enabled mobile device may be operable to enforce an AFC correction when the crystal oscillator drifts beyond a specific frequency error. The AFC correction may be allowed during time intervals corresponding to GNSS words at which decoding of these words is not required. The GNSS enabled mobile device may be operable to disable the AFC correction during time intervals associated with decoding of words while the crystal oscillator may drift within the specific frequency error range. After the decoding of one or more of words is completed, the AFC correction may be allowed during the time intervals corresponding to these words.
