摘要： An aided inertial navigation system and method for navigating a mobile object having constraints comprising an inertial measurement unit, a processor, and an error correction device. The inertial measurement unit provides acceleration data and/or angular velocity data of the mobile object. The processor is adapted to receive the acceleration data and/or angular velocity data, and to provide output data with position output indicative of position of the mobile object. The error correction device receives as input, state and dynamics information and auxiliary input data including map information associated with the path, speed data, wheel-angle data and discrete data. The error correction device provides as output, state corrections to the processor that enhance accuracy of the position output. The state corrections are used by the processor to estimate position of the mobile object based on the constraints to the mobile object and the map information associated with the path.

摘要： A location of interest is received by a server, and a buffer zone is determined surrounding that location. Real-time spatial events may be continually updated in one or more GIS databases. The database entries may be software spatial objects, which consist of the location and supplemental information pertaining to each event. All locations that are related to a spatial event may be listed in a relationship table. The location of interest is used to query the relationship table for events occurring within the location's buffer zone, and therefore affecting the location.

摘要： A navigation system with decryption functions. The navigation system may receive from a portable data storage medium an encrypted authentication key, an encrypted first portion of a geographic database, and an unencrypted second portion of the geographic database. The navigation system may then decrypt the encrypted authentication key so as to gain access to a set of verification information and to a decryption key for decryption of the encrypted first portion. The navigation system may then use the verification information to validate use of the database, such as by ensuring that the data storage medium is authorized to hold the database or that the navigation system is authorized to access the database. In turn, the navigation system may then use the decryption key to decrypt the encrypted first portion, so as to gain access to the database as a whole. The navigation system may then use information in the database to convert location coordinates into map information for presentation to a user. Also disclosed is a secure geographic database for use with a navigation system.

摘要： An advance notification system notifies users of the impending arrival of a vehicle, for example, an overnight package delivery vehicle, at a particular vehicle stop. The system generally includes an on-board vehicle control unit (VCU) for each vehicle and a base station control unit (BSCU) for sending messages to user computers in order to inform the users when the vehicle resides at a certain predefined time period, distance, prior stop, and/or location point from the vehicle stop. Moreover, vehicle tracking, the BSCU, a computer network (e.g., the Internet), and software located on a user computer may be combined in a plurality of configurations for launching and communicating a message of the impending arrival of a particular vehicle before it arrives. Significantly, the computer message is to advise of the impending arrival and preferably will exhibit a distinctive display and/or sound on the recipient computer so that the recipient is informed of the message. The VCU sends vehicle location and/or stop information to the BSCU, the BSCU compares the vehicle route stop list with route management software, then determines when to send an impending arrival message by preferences, normally chosen by the system operator or a user preparing to receive the advance notification message. The user computer displays information associated with the impending arrival of a vehicle in the form of the name of the vehicle, when the vehicle has finished a previous delivery, the miles before a stop, the time before arriving, and/or an actual location of a vehicle when a vehicle reaches a certain point/place. Additionally, other addressable communication devices could be used in place of or in addition to the computer message, such as personal pagers, mobile telephones, television box descramblers, etc. Users may also contact the computer site and/or computer address for impending arrival information.

摘要： Notification methods and systems are provided. One such method, among others, can be broadly summarized by the following steps: enabling a user to define at least two communications methods for receiving notifications relating to travel of a mobile thing; enabling a user to define one or more criteria when each communications method should be used as opposed to one or more others; monitoring travel data associated with the mobile thing; and providing a notification using one or more of the communications methods, based upon the criteria. A notification system, among others, would have a mechanism for performing each of the foregoing steps.

摘要： A receiver that uses a single processor to control a GPS sub-system and an inertial (“INS”) sub-system and, through software integration, shares GPS and INS position and covariance information between the sub-systems. The receiver time tags the INS measurement data using a counter that is slaved to GPS time, and the receiver then uses separate INS and GPS filters to produce GPS and INS position information that is synchronized in time. The GPS/INS receiver utilizes GPS position and associated covariance information in the updating of an INS Kalman filter, which provides updated system error information that is used in propagating inertial position, velocity and attitude. Whenever the receiver is stationary after initial movement, the INS sub-system performs “zero-velocity updates,” to more accurately compensate in the Kalman filter for component measurement biases and measurement noise. Further, if the receiver loses GPS satellite signals, the receiver utilizes the inertial position, velocity and covariance information provided by the Kalman filter in the GPS filters, to speed up GPS satellite signal re-acquisition and associated ambiguity resolution operations.
摘要翻译： 使用单个处理器来控制GPS子系统和惯性（“INS”）子系统并且通过软件集成的接收机在子系统之间共享GPS和INS位置和协方差信息。 接收机时间使用从机到GPS时间的计数器来标记INS测量数据，然后接收机使用单独的INS和GPS滤波器来产生在时间上同步的GPS和INS位置信息。 GPS / INS接收机在更新INS卡尔曼滤波器时使用GPS位置和相关协方差信息，其提供用于传播惯性位置，速度和姿态的更新的系统误差信息。 每当接收机在初始移动后静止时，INS子系统执行“零速度更新”，以更准确地补偿卡尔曼滤波器中的元件测量偏差和测量噪声。 此外，如果接收机丢失GPS卫星信号，则接收机利用GPS滤波器中的卡尔曼滤波器提供的惯性位置，速度和协方差信息，以加速GPS卫星信号重新获取和相关的模糊度解析操作。

摘要： A reporting program and system whereby end users of navigation systems, or other computing platforms that use geographic data to obtain navigation-related or map-related services, can make reports about the geographic data. The reporting program can be used by end users to report perceived errors or inaccuracies in the geographic data. The end users can use their own personal computers, or other computing devices, to access the reporting program over a network, such as the Internet. When an end user accesses the reporting program, the reporting program provides a graphical map image to the end user on the end user's computing platform. The reporting program allows the end user to zoom and pan the graphical map image in order to display an image of the area about which the end user wishes to make a report. When the area about which the end user wishes to make a report is displayed on the end user's display screen, the reporting program allows the end user to mark up the graphical map image to illustrate a change. The reporting program also allows the end user to include text to describe a change. The reporting program captures the end user's graphical and text input as a report that is used to update or check the geographic database, as appropriate.

摘要： A method and apparatus are provided for estimating an impedance through a node at an intersection between roads in a roadway network. The impedance may be measured in time or distance, for example. Characteristic information describes at least one feature of the intersecting roads. One or more pieces of characteristic information may impact the impedance of traffic through an intersection and are used to estimate the impedance through the node. Examples of characteristic information are speed information, road-type, network routing level, intersection angle information, one-way, and cross traffic turn information. An impedance factor, or a cost, is assigned to each piece of characteristic information. The cost may be positive if the characteristic information adds impedance to the node, or negative if the characteristic information subtracts impedance from the node.
