  • Patent number: 10908297
    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.

  • Patent number: 10895646
    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. Two filters, called “robustifier” and “main estimator” respectively, both use state variables and compute the values thereof based on: NSS signals observed by the NSS receiver, and/or information derived therefrom. The robustifier identifies, within the input data, measurements that do not match a stochastic model assigned thereto. For each identified measurement, the robustifier rejects the measurement, adjusts the stochastic model assigned to the measurement, and/or corrects the measurement. The robustifier uses fewer state variables than the main estimator. A corresponding system is also disclosed.

  • Patent number: 10872466
    Abstract: Techniques for displaying underground assets using a portable electronic device. A camera image of a ground having a ground surface may be captured. A placement of a virtual pit in the camera image may be determined. A pit view comprising the virtual pit and a virtual representation of an underground asset, and a superimposed image comprising the camera image and the pit view may be generated. A top opening of the virtual pit may align with the ground surface in the camera image. A portion of the virtual representation of the underground asset may be shown inside the virtual pit and below the top opening of the virtual pit such that a distance between the top opening and the portion of the virtual representation of the underground asset inside the virtual pit may provide a visual indication of a depth of the underground asset relative to the ground surface.

  • Patent number: 10845198
    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.

  • Patent number: 10830905
    Abstract: A system for vertical accuracy improvement includes a reference station, a rover, and a base station in communication with the reference station and the rover. The base station includes a GNSS antenna, an actuator coupled to the GNSS antenna, a wireless transceiver, a processor, and non-transitory computer readable media comprising instructions executable by the processor. The instructions may be executed to cause the base station to receive a first vertical error from the reference station. The base station may further be configured to determine a second vertical position at which the first vertical error is reduced, and adjust the GNSS antenna to be in the second vertical position. The base station may further be configured to generate correction data based at least in part on the phase of the carrier wave signal at the second vertical position, and transmit the correction data to the rover.

  • Patent number: 10816670
    Abstract: The invention relates to methods, notably carried out by global or regional navigation satellite system (NSS) receivers, which involve receiving satellite-specific, nadir-angle dependent correction information associated with each of at least two NSS satellites among a plurality of NSS satellites. The correction information is useful to correct observed NSS signals, so as to mitigate the effects of satellite-specific, nadir-angle dependent biases in the NSS signals, and thus improve the performance of position determination systems. The invention also relates to methods for generating such correction information, to methods for designing a satellite, to NSS receivers, to apparatuses for generating correction information to be sent to the receivers, and to computer programs and storage mediums.

  • Patent number: 10817732
    Abstract: An image may be obtained from one or more cameras coupled to a first vehicle. The image may be provided as input to a machine learning algorithm configured to determine whether an object depicted in the image corresponds to another vehicle and to determine size information and location information for the object. Output from the machine learning algorithm enables obtaining features including size and location information for a second vehicle that is identified in the image. The features may be used to determine whether the second vehicle is depicted within a predetermined region of the image including a predicted travel path of the first vehicle. The features may also be used to determine whether the second vehicle is within a predetermined proximity of the first vehicle. Thereafter, a determination may be generated as to whether there is a significant risk of collision between the first vehicle and the second vehicle.

  • Patent number: 10819938
    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.

  • Patent number: 10788591
    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.

  • Patent number: 10775299
    Abstract: A Light Emitting Diode (LED) is added to a weed control system for calibrating the weed control system. A detector generates an electrical signal based on receiving light emitted by the LED. An electronically-tunable capacitor of a bandpass filter is adjusted based the signal received from the detector to adjust a center frequency of the bandpass filter so that light from an optical source, different from the LED, can more efficiently be detected by the weed control system.
