Abstract: A method for processing and assessing the integrity of GNSS position information incudes (a) receiving GNSS signals and ascertaining a preliminary GNSS position, (b) checking the preliminary GNSS position ascertained in step (a) against a first condition and discarding the preliminary GNSS position if the first condition is satisfied, (c) ascertaining the integrity of the GNSS position based on an integrity criterion ascertained in the field which was determined excluding GNSS positions that satisfy the first condition, and (d) if the GNSS position was not discarded in step (b), outputting the preliminary GNSS position as a verified GNSS position.

Abstract: A method for detecting multi-level roads on the basis of GNSS includes (i) acquiring actually tracked GNSS satellites and the theoretically trackable GNSS satellites at a location, (ii) generating a point cloud representation using the actually tracked and the theoretically trackable GNSS satellites, (iii) discovering which theoretically trackable GNSS satellites cannot be tracked at the location, and (iv) detecting a road level as part of the detected positions when, in the point cloud representation, the discovered GNSS satellites are situated in a particular region corresponding to a roadway-like pattern.

Abstract: The method for starting a GNSS receiver arranged in a vehicle is disclosed. The method includes: (a) capturing, by way of an image capturing device, a first item of image information when the vehicle is started, wherein the first item of image information describes the environment of the vehicle when the vehicle is started; (b) comparing the first item of image information captured in step (a) with a second item of image information captured by the image capturing device when the vehicle is parked and describing the environment of the vehicle when the vehicle is parked in order to determine whether the first item of image information and the second item of image information deviate from each other, and (c) starting the GNSS receiver while taking the comparison result in step (b) into account.

Abstract: A method for monitoring trees endangering power lines using a vehicle network, which comprises a vehicle and a central computer, the vehicle including an image capturing sensor system, an image processing unit, and a locating system, and wirelessly connectable to the central computer in a data-conducting manner, and wherein the vehicle network covers a particular area and the vehicle can travel within the area, such that the trees endangering power lines within the area can be automatically monitored by the vehicle during a journey, includes capturing image information of an environment with the image capturing sensor system of a relevant vehicle during a journey, determining tree information with the image processing unit of the vehicle, taking into account power lines, based on the captured image information, and sending from the vehicle to the central computer the determined tree information and/or tree information evaluated by an evaluation unit of the vehicle.

Abstract: A method for GNSS-based localization of a vehicle includes receiving a first set of satellite orbit data, using the first set of satellite orbit data when determining a first localization result, receiving a second set of satellite orbit data, checking a plausibility of the first set of satellite orbit data using the second set of satellite orbit data, and manipulating the first set of satellite orbit data and/or the first localization result and/or a localization filter when the plausibility check was not successful.
