Abstract

A Global Navigation Satellite System (GNSS) receiver that includes a satellite signal generator generating signal data for a signal that is not being tracked by the receiver. The receiver includes a satellite signal generator running an algorithm to process first and second received signals to produce a software-synthesized satellite signal, and the generated signal data is used to correct bias or is communicated to a spaced-apart GNSS receiver or used for onboard positioning calculations. The satellite constellation may be the Galileo constellation, with the first and second signals being E5A and E5B signals tracked by the receiver and the generated third signal being an E5AltBOC signal. With a half-a-cycle bias resolution technique, the satellite signal generator generates synthetic E5AltBOC data of high quality. For a receiver, which physically tracks E5AltBOC, synthetic E5AltBOC may be used to monitor polarity of a physically tracked E5AltBOC and correct it if error is detected.

Abstract

A movable accessory for an automatic point layout system includes a laser receiver, target screen, and an array of LEDs. A laser controller aims a vertical laser light plane toward any desired point on the jobsite. The user moves the accessory into the laser light plane, thereby impacting a photosensor on the laser receiver. The accessory's electronic controller translates that laser light impact and illuminates a corresponding LED. The illuminated LED indicates the desired point of interest on the jobsite floor for the user to mark. An electronic distance measuring instrument (an LDM) aims along the same laser plane, and the target screen reflects the LDM signal to provide a distance reading, which is sent to a remote controller operated by the user. Alternatively, the LED array indicates where the laser plane strikes the photosensor, allowing the user to quickly move the accessory to the null position of the photosensor.

Abstract

A movable accessory for an automatic point layout system includes a laser receiver and an array of LEDs. Two laser controllers aim vertical laser light planes toward any desired point on the jobsite. The user moves the accessory into a first laser light plane, thereby impacting a photosensor on the laser receiver. The accessory's electronic controller translates that laser light impact and illuminates a corresponding LED in a first color. The user then moves the accessory into a second laser light plane, thereby impacting a photosensor on the laser receiver. The accessory's electronic controller translates that impact and illuminates a corresponding LED in a second, different color. The user then moves the accessory until the two LED colors intersect. When the intersect occurs, the accessory's electronic controller translates these impacts and illuminates a corresponding LED in a third, different color.

Abstract

Some embodiments of the invention relate to methods carried out by an NSS receiver and/or a processing entity capable of receiving data therefrom, for estimating parameters derived from NSS signals useful to determine a position, and for generating protection level(s) for an application relying on NSS observations to produce an estimate of said parameters. A float solution is computed using NSS signals observed by the NSS receiver. A best integer ambiguity combination that minimizes an error norm is identified based on the float solution. Additional integer ambiguity combinations are identified, which have the smallest error norms that, together with the error norm of the best integer ambiguity combination, jointly satisfy the integrity risk. A measure of spread of the best and additional integer ambiguity combinations is computed. The protection level(s) is then generated from the measure of spread. Systems and computer programs are also disclosed. Some embodiments may for example be used for safety-critical applications such as highly-automated driving and autonomous driving.

Abstract

A navigation system useful for providing speed and heading and other navigational data to a drive system of a moving body, e.g., a vehicle body or a mobile robot, to navigate through a space. The navigation system integrates an inertial navigation system, e.g., a unit or system based on an inertial measurement unit (IMU). with a vision-based navigation system unit or system such that the inertial navigation system can provide real time navigation data and the vision-based navigation can provide periodic, but more accurate, navigation data that is used to correct the inertial navigation system's output. The navigation system was designed with the goal in mind of providing low effort integration of inertial and video data. The methods and devices used in the new navigation system address problems associated with high accuracy dead reckoning systems (such as a typical vision-based navigation system) and enhance performance with low cost IMUs.

Abstract

A Position and Orientation Measurement Engine (POME) is a mobile camera system that can be used for accurate indoor measurement (e.g., at a construction site). The POME uses a plurality of cameras to acquire images of a plurality of targets. If locations of the plurality of targets are precisely known, images of the targets can be used to determine a position of the POME in relation to the plurality of targets. However, to precisely determine locations of the plurality of targets can be time consuming and/or use expensive equipment. This disclosure discusses how to use a camera system with an electronic distance measuring unit to determine locations of the plurality of targets.

Abstract

Methods, apparatuses and computer programs are disclosed for estimating, or at least for generating information usable to estimate, the heading of at least one axis of interest of a rigid body. Rigid body is equipped with an antenna of a navigation satellite system (NSS) receiver, and with sensor equipment comprising sensors such as a gyroscope, an angle sensor, and accelerometers, depending on the form of the invention. Rigid body is subject to a known motion comprising causing a point's horizontal position to change, the point being referred to as “point B”, while keeping another point's position, the point being referred to as “point A”, fixed relative to the Earth. Considering the motion constraint, an estimation of the heading is generated using sensor equipment data and NSS receiver data. The estimation of the heading may for example be used to estimate the position of any point of rigid body.

Abstract

A post-processing system providing forward processing (FP) of original GNSS raw data and alternative forward-backward processing (BP) of modified GNSS raw data and combining results of the FP and modified BP to enhance accuracy of position data derived from GNSS raw data. The post-processing system includes a GNSS processing engine, such as a real-time PVT engine, that processes GNSS raw data files as real time data streams equally for FP and BP. The backward processing is performed on a set of GNSS raw data that is mirrored from the original GNSS raw data. The modified BP uses the same algorithms of the PVT engine in a forward run but with the mirrored GNSS raw data to provide BP including position estimate with associated accuracy estimates for each data epoch. A forward/backward combiner combines results of the FP and the modified BP to provide final position data with enhanced precision.

Abstract

Systems and methods for identifying which of a plurality of signal types received by a global navigation satellite system (GNSS) receiver includes a spoofing signal. One method may include, for each particular signal type of the plurality of signal types, excluding the particular signal type, calculating a parameter of a GNSS receiver based on the received wireless signals having a plurality of remaining signal types, and calculating a residual score based on a variability associated with calculating the parameter, the residual score being one of a plurality of residual scores. The method may also include identifying an outlier of the plurality of residual scores and identifying which of the plurality of signal types includes a spoofing signal based on the outlier.

Abstract

A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.

Abstract

The invention relates to a method carried out by a navigation satellite system (NSS) receiver or a processing entity receiving data therefrom, for estimating parameters useful to determine a position. The NSS receiver observes NSS signals from NSS satellites over multiple epochs. A filter, called “precise estimator”, is operated, which uses state variables, makes use of NSS signals observed by the NSS receiver, and computes its state variable values based on observations that are not derived from NSS signals observed by the NSS receiver. Seeding information is obtained, and a constrained solution, called “seeding- and ambiguity-constrained solution”, is computed by constraining the ambiguities of the precise estimator by the seeding information, by resolving the resulting ambiguities, and by constraining at least one of the other state variables of the precise estimator by the resolved ambiguities. A corresponding system is also disclosed.

Abstract

Methods, apparatuses and computer programs are disclosed for estimating, or at least for generating information usable to estimate, the heading of at least one axis of interest of a rigid body. Rigid body is equipped with an antenna of a navigation satellite system (NSS) receiver, and with sensor equipment comprising sensors such as a gyroscope, an angle sensor, and accelerometers, depending on the form of the invention. Rigid body is subject to a known motion comprising causing a point's horizontal position to change, the point being referred to as “point B”, while keeping another point's position, the point being referred to as “point A”, fixed relative to the Earth. Considering the motion constraint, an estimation of the heading is generated using sensor equipment data and NSS receiver data. The estimation of the heading may for example be used to estimate the position of any point of rigid body.
