摘要： A method and an apparatus using a low Earth orbiting (LEO) satellite signal to augment the Global Positioning System (GPS) for finding a location vector between a GPS user receiver and a GPS reference receiver. The GPS user receiver computes a LEO user-reference carrier phase difference and a GPS user-reference carrier phase difference for the LEO satellite signal and a GPS satellite signal, respectively, received simultaneously at the GPS user receiver and the GPS reference receiver. Carrier phase double differences are computed from a difference between the GPS user-reference carrier phases from two GPS satellites and either the LEO user-reference carrier phases from two LEO satellites or the GPS user-reference carrier phase from one GPS satellite and the LEO user-reference carrier phase from one LEO satellite. The location vector is computed from a difference between the double differences for two satellite geometries. The GPS reference receiver communicates the reference carrier phase data to the GPS user receiver through the LEO satellite. An ionospheric delay model is determined by tracking the LEO satellite signal as the LEO satellite traverses the sky. An optional calibrator corrects for measurement delay in determining the carrier phases in the GPS user receiver and the GPS reference receiver.

摘要： In a system having plural signal-carrying channels, a phase shift is introduced between a signal in one of the channels and a reference signal for calibrating the individual channels. The phase shift is introduced by phase-shift apparatus responsive to a command signal directing the continuous monotonic increment of phase. The apparatus may be contained within each channel for use in the signal-carrying process, or may be placed in the reference channel for use solely in the calibration process. The phase incrementing introduces a frequency shift (a serrodyning) which produces a beat-frequency signal upon mixing a channel signal with a reference signal. The beat-frequency signal is phase locked to a modulation pattern of the command signal whereby a measurement of phase (or delay) can be made between the two signals for calibration of each channel within the system.

摘要： An apparatus and a method for providing a global localization output are provided. When the apparatus receives navigation signals, the apparatus processes the signals to determine, based on a fixed earth-centered, earth-fixed (ECEF) reference pose of a reference point in an ECEF coordinate, a new ECEF pose, and to convert the fixed ECEF reference pose to an east-north-up (ENU) reference pose in an ENU coordinate. When the apparatus determines that a jump occurs in the new ECEF pose based on a pose change between the new ECEF pose and a previous ECEF pose, the apparatus calculates a reference shift of the ENU reference pose based on the pose change to absorb the jump in the ENU coordinate, and updates the ENU reference pose based on the reference shift. Thus, a new ENU local pose may be obtained using the ENU reference pose.

摘要： A measuring device serves the purpose of testing a location tracking of a device under test. The measuring device comprises a global navigation satellite system simulator adapted to wirelessly transmit a radio frequency global navigation satellite system signal to a device under test, and a base station simulator adapted to wirelessly transmit a real-time kinematic signal to the device under test. The measuring device is adapted to compare a location, determined by the device under test based on the radio frequency global navigation satellite system signal and the real-time kinematic signal, with an ideal location, upon which the radio frequency global navigation satellite system signal and the real-time kinematic signal are based.

摘要： A system and method for vehicle-tracking and localization with a distributed sensor network is provided that includes a plurality of cellular station. A pilot signal is received from the vehicle with an arbitrary station. The pilot signal is compared to each vehicle profile with the arbitrary station in order to identify a matching profile. Spatial positioning data is received for the vehicle with the arbitrary station. The vehicle profile and the spatial positioning data is relayed from the arbitrary station to the at least one proximal station from the plurality of cellular stations. A plurality of iterations is executed. The spatial positioning data is compiled from each iteration into a predicted path for the vehicle with the cellular stations. A warning notification is sent from the arbitrary station of the current iteration to the vehicle, if the predicted path is intersected by at least one hazard.

摘要： A quick positioning method and a vehicle-mounted system are disclosed. The quick positioning method includes: acquiring position information from an external positioning terminal the same time when the vehicle-mounted system is started, and determining continuously whether position information is available from a local GPS positioning module; and using the position information acquired from the external positioning terminal until position information is available from the local GPS positioning module. By the above method, there would be available position information before the GPS module of the vehicle-mounted system is fully activated, thus effectively enhancing the positioning efficiency of the vehicle-mounted system.
