摘要： A vehicle information system which includes an in-vehicle system 105 and a centralized server system 120. The in-vehicle system communicates with the server system using a wireless communication link 110, such as over a cellular telephone system. A position system, such as a set of GPS satellites 140, provides positioning signals that are used by the in-vehicle systems, and optionally by the centralized server system to increase the accuracy of position estimates. In one version of the system, an operator specifies a destination to an in-vehicle system which validates the destination. The in-vehicle system transmits specification of the destination to a server system 125 at the centralized server. The server system computes a route to the destination and transmits the computed route to the in-vehicle system. The in-vehicle system guides the operator along the route. If the in-vehicle system detects that the vehicle has deviated from the planned route, it replans a new route to the destination using an in-vehicle map database.

摘要： A system using GPS data for locating a person requesting a support. The system includes a mobile terminal carried by a person to acquire the GPS data from GPS satellites and transmits the same upon a request by the person to a message center where the GPS data is processed to calculate the person(s position. The mobile terminal simply acquires the GPS data which is invalid for calculation of the position if the request is made where the GPS satellite is not available. For successfully locating the person's position, the mobile terminal acquires the GPS data regularly at different times in accordance with a time schedule and stores the time-series sets of the GPS data which are transmitted together with a current GPS data acquired in response to the support request, thereby giving the latest available position of the person if the current GPS data is found invalid.

摘要： A navigation-satellite receiver comprises a crystal oscillator that is affected by local ambient temperature in a repeatable way. After locking onto a GPS satellite, the receiver is used to calculate the true frequency bias of the local crystal oscillator. GPS-system lock provides an atomic-clock basis for such measurements of true frequency. The current temperature of the crystal is measured and recorded in association with the true frequency bias measurement. The data is then used to generate a ninth-order polynomial that describes the frequency drift of the crystal over temperature. Then during receiver initialization when the local reference oscillator is not in lock, the ambient temperature is measured and used to index the ninth-order polynomial to estimate the actual crystal frequency. Such frequency estimate is then used as a basis to find signal from visible SV's in an overhead constellation.

摘要： A real-time integrated vehicle positioning method and system with differential GPS can substantially solve the problems encountered in either the global positioning system-only or the inertial navigation system-only, such as loss of global positioning satellite signal, sensitivity to jamming and spoofing, and an inertial solution's drift over time. In the present invention, the velocity and acceleration from an inertial navigation processor of the integrated GPS/INS system are used to aid the code and carrier phase tracking of the global positioning system satellite signals, so as to enhance the performance of the global positioning and inertial integration system, even in heavy jamming and high dynamic environments. To improve the accuracy of the integrated GPS/INS navigation system, phase measurements are used and the idea of the differential GPS is employed. However, integer ambiguities have to be resolved for high accuracy positioning. Therefore, in the present invention a new on-the-fly ambiguity resolution technique is disclosed to resolve double difference integer ambiguities. The real-time fully-coupled GPS/IMU vehicle positioning system includes an IMU (inertial measurement unit), a GPS processor, and a data link which are connected to a central navigation processor to produce a navigation solution that is output to an I/O (input/output) interface.
