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

The invention relates to optical surveying such as in building construction, road construction, landscaping and similar. A first image sensor obtains in a first wavelength range a first image of a scene within a field of view captured by an optical arrangement such as a telescope. A light emitter emits light in a second wavelength range and a second image sensor obtains a second image of the field of view in the second wavelength range. A target position of a reflecting target is found in the first image by detecting a known image pattern of the reflecting target in the first image. A region of interest in the second image is then a defined based on the identified target position in the first image, for detecting a reflector position of a reflector of the reflecting target in the region of interest. With the invention it becomes possible to improve the identification of a reflective target at reduced processing time, even if reflections from other objects than the reflective target are present.

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

Techniques for transmitting global navigation satellite system (GNSS) correction data to a rover. GNSS signals are wirelessly received by a base station from one or more GNSS satellites. GNSS correction data is generated by the base station based on the GNSS signals. A beacon frame is formed by the base station to include a frame header, a frame body, and a frame check sequence (FCS). The frame body is formed to include the GNSS correction data. The beacon frame is wirelessly transmitted by the base station for receipt by the rover. The rover wirelessly receives the beacon frame. The GNSS correction data is extracted by the rover from the beacon frame. A geospatial position of the rover is calculated based on the GNSS correction data.

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

Methods for controlling a plant detection system include determining a target phase delay based on a first phase delay of reflected portions of a first light beam and a second phase delay of reflected portions of a second light beam. A composite light beam comprising the first light beam and the second light beam is emitter towards bare soil, and reflected portions of the composite light beam are detected. An intensity of at least one of the first light beam or the second light beam is adjusted so that a phase delay of the composite light beam is approximately equal to the target phase delay.
