摘要： A Global Navigation Satellite System (GNSS) device, such as the Global Positioning System (GPS) device, uses satellite orbital position information from almanac and/or ephemeris data to change a search parameter, such as reducing the number of analyzed frequency bins or setting signal strength threshold, so that satellite signal acquisition times are reduced. An exemplary embodiment estimates an orbital position for at least one GNSS satellite based upon at least one of almanac data and ephemeris data, detects a signal emitted from the at least one GNSS satellite, and based upon the estimated orbital position information for the at least one GNSS satellite that is determined from the almanac data and the ephemeris data, adjusts at least one parameter used in the analysis of the detected signal.

摘要： A navigation system includes an inertial measurement unit, a navigation computer, a GPS receiver, and a clock controller. The inertial measurement unit has a first clock and a first switch, the navigation computer has a second clock and a second switch, and the GPS receiver has a third clock. The clock controller controls the first and second switches. Accordingly, the inertial measurement unit, the navigation computer, and the GPS receiver may use their own clocks, or the inertial measurement unit and the navigation computer may use the second clock, or the inertial measurement unit, the navigation computer, and the GPS receiver may use the third clock.

摘要： A method and a system for providing a substituted timing signal for a missing satellite ephemeris in execution of a RAIM algorithm includes deriving a plurality of position, velocity, and time solutions from a GPS navigation system. The position, velocity and time solutions are derived from a plurality of satellite ephemerides. An atomic clock provides an atomic clock signal. The atomic clock signal is compared to the derived time solutions to arrive at a correction factor. The atomic clock signal is adjusted according to the correction factor to develop an adjusted atomic clock signal. The adjusted atomic clock signal is substituted for a missing satellite ephemeris to execute the RAIM algorithm.

摘要： A GPS receiver acquires GPS data from at least one GPS satellite. A code offset and a frequency offset are determined based on the acquired GPS data. A change in GPS position of the GPS receiver during the determination of the code offset is determined, and a change in rate of the GPS receiver during the determination of the frequency offset is also determined. The code offset is updated based on the change in GPS position, and the frequency offset is updated based on the change in rate. The updated code offset and the updated frequency offset are handed over to a tracking function.
