摘要： A satellite navigation system using multiple antennas for providing the position of multiple fiduciary points on an object even when fewer than four satellites are visible to some or all the antennas. Satellite signals from the multiple antennas are fed into at least one receiver. The receiver or receivers utilize constraint information, which is independent of the satellite signals. These external constraints are used to augment the signals received from the satellites, to obtain the position solution for each antenna. In a preferred embodiment, a common reference clock is used to provide an external constraint. Examples of other external constraints that can be used in the current invention are distance between the antennas, inertial measurement of attitude, rotational or linear position sensors, etc.

摘要： A position determination device for a mobile terminal acquires pseudorandom codes and navigation data contained in received signals and associated augmentation data representative of an instantaneous approximate position of the terminal and an associated radius of protection contained in received messages. In the presence of a radius of protection corresponding to a quality level lower than a chosen quality level or in the momentary absence of a radius of protection associated with an approximate position at a time T, an estimated radius of protection is determined as a function of a weighting law applied to a chosen number of earlier radii of protection. An estimated position of the terminal at the time T is then determined as a function of at least the estimated radius of protection and the pseudorandom codes, navigation data and approximate position acquired at the time T.

摘要： A position measurement device measures a position even in the case where the number of satellites necessary for position measurement with GPS cannot be ensured. In the case where the number of satellites necessary for position measurement cannot be acquired, a first position measurement device measures the position by finding the displacement distance from the nearest position, on the basis of three-dimensional acceleration detected by a three-dimensional acceleration sensor.

摘要： A track model is created for use with a GPS receiver. In one embodiment, the track model is a set of planar surfaces which approximate the contiguous surface on which navigation takes place. The GPS receiver searches for an appropriate planar surface associated with its approximate position. Having found the appropriate planar surface, the GPS receiver constrains its position using the planar surface associated with its approximate position. Using the track model improves the accuracy of the computed position at the time and improves the ambiguity estimation process so that positions with greatly improved accuracy are available sooner.

摘要： A terrestrial C/A code GPS receiver system digitally samples, filters and stores a segment of 11 half chips of the received composite as a binary number and multiplexes this number for parallel correlation with each of a series of multibit code replicas for the satellites to be tracked. Each of the time delay specific correlation products are accumulated in a cell of a memory matrix so that at least twenty two delays for each satellite may be evaluated each code period providing fast reacquisition, even within a city intersection, as well as correction of multipath tracking and multipath interference. All cells of the memory matrix may be used for an acquisition of a single satellite in about 4 ms. Two satellite tracking, in addition to altitude hold, uses cross track hold alternating with clock hold to update the cross track estimate. Single satellite tracking uses cross track and clock hold together. Navigation data is updated with detected changes in motion including turns.

摘要： The present invention relates to a method for calculating the instantaneous characteristics of a satellite in orbit equipped with a GNSS receiver, capable of performing measurements of pseudo-distance, when fewer than four transmitters are simultaneously in visibility. This method comprises the following stages: a first stage (20) of pre-processing of quantities measured by the receiver to deliver measurements of pseudo-distance, pseudo-speed and instantaneous pseudo-accelerations; a second stage (21) of mathematically processing these measurements, enhanced by the knowledge of complementary data concerning the orbit of the receiver satellite and the receiver, delivering several solutions, a third stage (22) of physically filtering these solutions delivering the position and the speed of the receiver satellite as well as the clock bias and drift of the receiver.

摘要： The portable device (10) is used for determining horizontal and vertical positions. It includes a pressure sensor altimeter (15) calibrated to a predetermined initial altitude, a GPS signal receiver (12) arranged to receive, via an antenna (11), signals originating from several satellites (20) in order to calculate position data of the device, a processing unit (14) receiving the position data from the receiver (12) and an altitude value from the altimeter (15), and display means (16) for the horizontal and vertical positions of the device processed and provided by the processing unit. The processing unit sends the GPS receiver a signal corresponding to the altitude value of the calibrated altimeter to enable the receiver to determine, using the altitude value, the position data of the device. A memory (13) including cartographic data and associated with the GPS receiver (12) can provide the precise data to the processing unit (14) in particular for calibrating the altimeter.
