摘要： A system determines three-dimensional attitude of a moving platform using signals from two closely spaced Global Positioning System (GPS) antennas. The system includes three rate gyroscopes and three accelerometers rigidly mounted in a fixed relationship to the platform to aid in determining the attitude. The system applies signals from a first of the two GPS antennas to sufficient channels of a GPS receiver to support navigation. The system applies signals from a second of the two GPS antennas to the remaining receive channels, which are configured to support interferometry. The system optimally selects the navigation and interferometry channels to provide an interferometric heading solution. The system resolves the ambiguity normally associated with the interferometric heading solution by having the closely spaced GPS antennas and using interferometry to refine a coarse heading estimate from a GPS plus Inertial Measurement Unit (IMU) transfer alignment solution. The system achieves close sub-meter spacing of the two GPS antennas by merging many temporal interferometric measurements that result from an attitude memory provided by the IMU time-history solution.

摘要： A navigation system includes sensors to detect a moving direction and location of a mobile body. The navigation system first presumes a first route pattern, which includes straight and curve ways, from data supplied from the sensors. The navigation system then determines a second route pattern, based on data supplied from the sensors. The navigation system compares the first route pattern with the second route pattern. When the first route pattern is substantially the same as the second route pattern, a current moving direction and location of the mobile body detected by the sensors are calibrated in accordance with the first route pattern. The navigation system can accurately determine a current location of the mobile body even if the mobile body moves in a roofed building and no driveway data is available for the building.

摘要： The present invention provides a system, a method and a computer usable medium including a program for a vehicle that has traveled off of a planned route. This may be done by providing a plurality of nodes located on road segments, generating a plurality of pre-established checkpoints at intersections and receiving a signal including a location coordinate identifying current vehicle position. It may also be done by comparing the vehicle coordinates to the coordinates of checkpoints, constructing a proximity ellipse in response to the aforementioned comparison and identifying at least one return path cycle within the ellipse with acceptable road segments that allow travel back to a planned route.

摘要： A system and method for real time vehicle guidance by Central Traffic Unit are presented. The proposed vehicle Guidance System includes a plurality of vehicles equipped with Individual Mobile Units including GPS units (position determining systems adapted to determine their present position) and communicatively linked to the Central Traffic Unit computer server. The Central Traffic Unit broadcasts the updated traffic patterns in real time thereby enabling the Individual Mobile Units to dynamically calculate the desired optimal travel paths. In response to a request from a driver for a route update from his present position to a desired destination, the Individual Mobile Unit searches for an optimal (usually fastest) route and shows it to the driver. In route searching by the minimal time criterion, the Individual Mobile Unit relies on estimated travel times stored in its database, and may also use current real time information on bottleneck situations received from Central Traffic Unit. The forecasting system allows the driver to enter alternative time schedules for the same destination and receive alternative travel time estimates for the same destination depending on the estimated traffic volumes on the roads at that particular time. The backbone of the system is a group of Sample Mobile Units equipped with RF transmitters that communicate their present position to the Central Traffic Unit at predetermined time intervals. The Central Traffic Unit uses those sample vehicles as antennas by tracking their positions for creating and maintaining a network of real time traffic load disposition in various geographical areas. To be able to detect a bottleneck situation when it arises and to estimate a current travel time for a corresponding section of road, the Central Traffic Unit maintains a list of sample vehicles that recently exited that section. If the times those vehicles have spent on the section differ considerably from a regular time stored in the database, Central Traffic Unit uses statistical tools for forecasting the future travel time along this section. Simultaneously, the Central Traffic Unit broadcasts updated travel times and any new information on current traffic jams and slow-down bottleneck situations in a given geographical location.

In one embodiment, the first location corresponds to a road segment in the map database nearest the vehicle location. In another embodiment, the processor is configured to identify an intermediate location on the route and generate a directional indicator on the display which indicates the direction to the intermediate location. In yet another embodiment, the processor is configured to automatically select an appropriate intermediate location in accordance with the measured angle between the vehicle heading and the intermediate location.
