  • Publication number: 20200293037
    Abstract: A system is configured for confirming a mobile cooperative target being automatically tracked and measured by a total station or theodolite in order to automatically control a machine operation of a construction site machine. The system includes at least one total station or theodolite with a UWBST anchor-module having an anchor-ID, and a cooperative target associated with a UWBST tag-module having a tag-identifier (tag-ID) and being used for automatically controlling a machine operation of the construction site machine. The system can include a machine control unit associated with the construction site machine configured for controlling machine operations based on tracking and continuously measuring cooperative targets carried out by the total station or theodolite, and an ultra-wide band (UWB) distance meter associated with the UWBST anchor-module configured for measuring a distance (UWB-distance) between the UWBST anchor-module and the UWBST tag-module.

  • Patent number: 10704233
    Abstract: A method and system that compensates for kinematic accelerations influencing a sensor measurement of working equipment such as an excavator. The method and system identify members of the working equipment that are movable relative to each other (e.g. stick, boom, bucket) and define a co-ordinate frame for each movable member. A kinematic relationship, preferably a kinematic chain. The sensor measurement is then modified according to the kinematic relationships and the relative position of each identified member.

  • Patent number: 10698042
    Abstract: A system and method that compensates for local disturbances in magnetometer measurements for working equipment. For example, compensating for magnetometer disturbances caused by a stick, boom, and bucket of an excavator. The compensation is performed by generating or obtaining a magnetic model of movable members, determining the position of each of the movable members, calculating an estimated magnetic disturbance, and modifying the magnetometer measurement.

  • Publication number: 20190164361
    Abstract: A method for monitoring activities of a construction or mining vehicle. Signals from at least one acceleration sensor, accelerometer (2), and/or at least one angular rate sensor, gyro (4), are processed on a computing platform (3) which is programmed to determine the activity state of the vehicle based on signals received. A device arranged to perform the method may also comprise means (7) for storing or communicating the result of the determination of the computing platform (3).

  • Patent number: 9541392
    Abstract: Surveying system for measuring the position of a measuring point on the ground is disclosed. The surveying system may include a survey pole with a body having a pointer tip for contacting the measuring point and position giving means for making available the coordinative determination of a referenced position, being placed on the body with a defined spatial relationship relative to the tip. Determination means may be included for repeatedly determining the referenced position of the position giving means. Evaluation means may also be included for deriving the position of the measuring point. In some embodiments, the survey pole may also include an inertial measuring unit placed on the body with a defined spatial relationship relative to the position giving means.

  • Patent number: 9008988
    Abstract: A method of calibrating inertial sensors of working equipment, such as a vehicle or survey equipment, includes determining whether the working equipment is in operation or not. Data is captured from inertial sensors and associated temperature sensors while the working equipment is out of operation. The captured data is used to update a thermal bias error model for the inertial sensors.

  • Patent number: 8600601
    Abstract: A positioning method that calculates a lower accuracy positioning solution and applies an offset to the lower accuracy positioning solution to form a final positioning solution if a higher accuracy positioning solution is unavailable. The offset represents a difference between the lower accuracy positioning solution and the higher accuracy positioning solution at a point in time when the higher accuracy positioning solution was last available.
