摘要： A method for determining the location coordinates (x, y, z) of a mobile terminal (MS) with respect to reference elements (SRB1,……, SRBn; Sat1, . , Satm) adapted to send towards said mobile terminal (MS) radioelectric signals involves the steps of measuring the radioelectric signals to derive respective measurements (?k),said measurements (?k) being affected by measurement errors, and subjections the measurements (?k) to state-based statistical filtering (xk+1, yk+1, zk+1), such as a kalman filtering, to derive therefrom the location coordinates of the mobile terminal. At least some of the reference elements are terrestrial reference elements (SRB1, …… , SRBn) and in the statistical filtering at least one further state (tk) is included in addiction to the coordinates. The further state (tk) is representative of the measurement errors. The terminal is adapted to be mounted on a vehicle such as a motorcar and to have associated therewith measurement source such as an altimeter adapted to provide additional measurements indicative of the location (e.g. the altitude) and/or the displacement of the mobile terminal (MS).

摘要： A real-time integrated navigation system for a vehicle includes a GPS receiver, connected to a first antenna, where the GPS receiver receives GPS data from satellites and outputs GPS position data. The system also includes a communications link, connected to a second antenna and to the GPS receiver, receiving range and carrier phase measurements from at least one base station. The system further includes navigation aids which provide relative position data of said vehicle and a Kalman filter, connected to the output of the GPS receiver and the navigation aids, that integrates the GPS position data and the relative position data and outputs smoothed position data. The smoothed position data is used in transportation applications, especially detection of lane departure. This GPS-based positioning system is suitable for highway speeds during all weather conditions.

摘要： An apparatus (10) and method for determining the position of a work implement (12) movably connected to a machine (16) utilizes first and second electromagnetic radiation receiving devices (18, 20) connected to the work implement (12) at predetermined spaced locations. A processor (24) determines the first and second current coordinate positions of the first and second receiving devices (18, 20) in a site coordinate system based on position signals from the first and second receiving devices (18, 20). The processor transforms the first and second receiving points (R, L) from a local coordinate system related to the machine (16) to the site coordinate system using a plane (98) passing through the first and second current coordinate positions and a mid-point (C) located along a substantially straight line (99) passing between first and second previously defined coordinate positions of the first and second receiving devices (18, 20). The processor (51) corrects the position of the first and second receiving points (R, L) in the site coordinate system based on sensed changes in the pitch of the implement (12).

摘要： Disclosed is a self-surveying relative GPS (Global Positioning System) weapon guidance system (10). This guidance system (10) includes multiple GPS satellites (12-18) which transmit GPS data to a ground sensor (20). The ground sensor (20) includes a GPS receiver (24), a self-surveying computer (28), a data formatter (30) and a transmitter (32). The GPS receiver (24) receives the GPS data and determines a second location of the ground sensor (20) based on the GPS data. The self-surveying computer (28) determines a first location of the ground sensor (20) based on the GPS data gathered over time, which is more accurate than the second location. The data formatter (30) determines a GPS error between the first and second locations which is transmitted by the transmitter (32). The GPS error is used by guided weapons in the vicinity of the ground sensor (20) to substantially increase the delivery accuracy of the guided weapons (40).

摘要： A Global navigation satellite-based systems (GNSS) enabled device, handling at least two of a plurality of sensors, collects GNSS measurements and navigation related non-GNSS sensor data. The collected navigation related non-GNSS sensor data is automatically formatted into a data format that is compatible with a format of the GNSS measurements. The formatted navigation related non-GNSS sensor data and the GNSS measurements are utilized by a single function to compute navigation information for the GNSS enabled device regardless of sensor configurations such as a cellular radio and/or a motion sensor. Measurement errors in the collected navigation related non-GNSS sensor data is estimated to determine measurement accuracy. The collected navigation related non-GNSS sensor data is selectively adopted, combined with the GNSS measurements, to compute navigation information by the single function based on the determined measurement accuracy. The computed navigation information may be utilized to calibrate sensor and/or sensor data when needed.

The base station is configured to receive an estimated location of the base station at a receiver coupled to the base station and determine a correction measurement based on the estimated location of the base station and a known location of the base station. The tracking device is configured to obtain an estimated location of a target object, receive an estimated location of the tracking device at a receiver coupled to the tracking device, determine a relative position between the target object and the tracking device based on the estimated location of the target object, the estimated location of the tracking device, and the correction measurement, and control a movement of the tracking device according to the relative position.
