Abstract: A Global Navigation Satellite System (GNSS) patch antenna can include a set of layers, a set of channels, and a set of conduction pins. The set of layers can include at least one layer with an electrically conductive antenna element configured to receive GNSS signals and another layer including a ground well. The set of channels can be aligned between the set of layers and can extend through the set of layers. The set of conduction pins can be located in the set of channels. Each conduction pin of the set of conduction pins can include a set of vias coupled by one or more donut-shaped connection pads at each interface between the set of layers.

Abstract: A system for surveying includes, a base station, for being positioned with respect to an environment, and an augmented-reality device. The augmented-reality device, such as a head-mounted display, has one or more cameras. An image of the base station is acquired by at least of the one or more cameras. An offset from the augmented-reality device to the base station is calculated based on the image. A position of the augmented-reality device with respect to the environment is calculated based on the offset and the base station positioned with respect to the environment. A virtual object in relation to the environment can then be presented to a user, using the augmented-reality device.

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 Global Navigation Satellite System (GNSS) patch antenna can include a middle laminate, a top laminate, a bottom laminate, and a ground well. The middle laminate can include a first side and a second side. The top laminate can be coupled to the middle laminate and can be positioned on the first side of the middle laminate. The top laminate can include an electrically conductive antenna element configured to receive GNSS signals. The bottom laminate can be coupled to the middle laminate and can be positioned on the second side of the middle laminate. The ground well can cover exposed surfaces of the bottom laminate and exposed portions of the second side of the middle laminate and can comprise electrically conductive material. Some of the surface of the middle laminate that is covered by the bottom laminate can be free from the electrically conductive material.

Abstract: Some embodiments of the invention pertain to generating (s10) and providing (s20) ionospheric disturbance information from navigation satellite system (NSS) reference stations or reference station system to NSS receivers or NSS receiver systems. Station-specific and/or satellite-specific ionospheric disturbance information may be obtained (s40) on the receiver side for mitigation purposes (s60, s70, s80) in the context of estimating parameters useful to determine a position. The ionospheric disturbance information may for example comprise ionospheric amplitude scintillation information, ionospheric phase scintillation information, and/or ionospheric delay gradient information. Systems, vehicles, and computer programs are also disclosed.

Abstract: Disclosed are a method and apparatus are provided for determining the amount of obstruction of a view of a satellite. An estimated satellite location from a satellite signal is mapped to a matrix of obstructions. A window is determined around the satellite location and all the obstructions within the window are considered in determining whether the satellite is obstructed, with the window considering the degree of possible error within the various measurements. In embodiments, the window size if varied based on the estimated amount of error and location of the satellite within the matrix.

Abstract: Computation of optimal embeddings for an optimization problem to be solved using a quantum annealer can be accelerated by pre-computing optimal embeddings in a target graph corresponding to a quantum processor architecture of clique graphs (or fully-connected network graphs) having various numbers of nodes. Pre-computed embeddings can be stored in a library. To solve an optimization problem, a clique-graph embedding of appropriate size can be retrieved from the library and modified to match the problem to be solved. The modified embedding can be executed using an appropriate quantum annealer.

Abstract: Marking metadata during layout can be time intensive. A robotic device is used to mark out points at a construction site, and an augmented-reality device uses the points for alignment and provides metadata about the points to a user of the augmented-reality device as the user looks at the points.

Abstract: Construction vehicles using a teach and repeat system can ascertain boundaries of a task area while working, without knowing a perimeter of the task area before starting the task. The system maps a first path of the vehicle by recording a position of a vehicle moving from a first start position to a first end position. A second path is predicted, based on a shape of the first path, the second path having a second start position and a second end position. A third path is mapped from a third start position to a third end position. Boundaries of the task area are ascertained based on the first path, the first start position, the second start position, the third start position, the third path, the first end position, the second end position, and the third end position.

Abstract: An augmented-reality device is used with a surveying system to guide a base station, such as a total station, during relock after loss of line of sight with a surveying instrument, such as a surveying pole with a reflective prism. A position of the surveying instrument in relation to the augmented-reality device is calculated while an object in the environment blocks line of sight from the base station to the surveying instrument. A position of the surveying instrument in relation to the environment is calculated based on the position of the surveying instrument in relation to the augmented-reality device. The position of the surveying instrument in relation to the environment is used by the base station to point toward to the surveying instrument.
