A quick release assembly or interface, which is designed for simple construction and no moving parts, is provided in the receiver housing and battery pack that includes a pair of magnets such that the receiver housing is attached to the battery pack via magnetic attraction or forces rather than with threaded connections or a more complex disconnect with multiple moving parts. Each magnet is a permanent magnet that is programmed or encoded with multi-poles or patterns. The magnets are affixed to or within the receiver housing and battery pack such that an attractive magnetic force is generated between the two magnets only when the two housings are properly aligned. A small amount of rotation from this aligned configuration causes the two magnets to generate repelling or repulsion forces that facilitate ready disassembly or removal of the battery pack.

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. An estimator is operated, which uses state variables and computes the values thereof based on delta observables computed for a previous epoch. Previous residuals are obtained from the estimator, each previous residual being associated with a delta observable computed for the previous epoch. The previous residuals are then adjusted using a back-residual coefficient. Delta observables for a current epoch are computed. For each of at least some of the delta observables, the delta observable computed for the current epoch is corrected using the adjusted previous residual associated with the delta observable. The estimator is then operated for the current epoch at least based on the corrected delta observables.

Abstract

A method for aligning two surveying instruments in a common space in a process that uses an autocollimation of a collimated light beam transmitted by a first surveying instrument and reflected by a second surveying instrument. In the alignment process, the first surveying instrument may emit a collimated light beam towards the second the surveying instrument and receive a reflection of the collimated light beam from the second surveying instrument in an autocollimator. The reflection may be generated for example by a mirror at the second surveying instrument. When the light beam is reflected such that autocollimation of the collimated light beam is achieved at the first surveying instrument, the first and second surveying instruments are in a predetermined positional relation with respect to one another. With a known predetermined positional relation between the reflecting mirror and the line of sight of the second surveying instrument, measurements by both surveying instruments can be made in a common coordinate system.

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 and detecting outliers in NSS observables. Input data comprising signals observed by the receiver is received. An estimator is operated, which uses state variables and computes the values thereof based on the input data. An outlier detection procedure comprises: computing a first statistic based on data outputted from the estimator and associated with a set of observables; identifying an observable candidate for removal; computing a second statistic based on the data outputted from the estimator from which the data associated with the identified observable is removed; and determining whether the ratio of the first to the second statistic exceeds a threshold and, if so, removing the identified observable, having the estimator recompute its state variables and performing the outlier detection procedure again.

Abstract

A sampling device receives, from a transducer computing device located within a predefined proximity to an equipment in an operating environment, a vibration sample from the operating environment and increments a retrain counter. In response to determining that the incremented retrain counter does not meet or exceed a retrain threshold, the sampling device predicts, using a model, an anomalous or non-anomalous designation for the vibration sample and a cluster assignment, to a particular cluster of a set of clusters, for the vibration sample when the model predicts the non-anomalous designation for the vibration sample. The sampling device receives a subsequent vibration sample and further increments the retrain counter. In response to determining that the further incremented retrain counter exceeds a retrain threshold, the sampling device receives a subsequent set of vibration samples and retrains, using the subsequent vibration sample and the subsequent set of vibration samples, the model.

Abstract

Described herein are systems, methods, and other techniques for controlling a velocity of an implement-equipped machine. An actual position of the implement-equipped machine is estimated based on sensor data captured using the machine's sensors. A cross track error between a target position and the actual position is calculated. An actual cross track error metric is calculated based on the cross track error. The actual cross track error metric is compared to a target cross track error metric to determine a velocity adjustment, where the velocity adjustment is determined so as to reduce a difference between the actual cross track error metric and the target cross track error metric. The velocity of the implement-equipped machine is adjusted by the velocity adjustment.

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 surveying pole is part of a primary surveying system (e.g., a Global Navigation Satellite System (GNSS) or a total station). Cameras are mounted to the surveying pole and used for ground tracking as the survey pole is moved from a place where the primary surveying system is unimpeded to an environment where the primary surveying system is impaired (e.g., to a GNSS-impaired environment or to a position that is blocked from view of the total station). Using ground tracking and/or other sensors, surveying can be continued even though the primary surveying system is impaired.

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

Methods for determining corrected positions of a global navigation satellite system (GNSS) rover using a GNSS base station and one or more GNSS reference stations include determining a statistical representation of position measurements from the GNSS reference stations and an instantaneous position measurement from the GNSS reference stations. A position correction is determined based on the statistical representation and the instantaneous position measurement. A corrected position of the GNSS rover is determined based on a position of the GNSS rover and the position correction.

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.
