A method for predicting GNSS geolocation quality on roads in urban environments given the propagation of objects obstructing GNSS signals is disclosed. The method includes step a) providing a model for determining the at least one geolocation quality parameter as a function of input values, wherein the model is designed for at least the following input values: (i) at least one DOP value describing the quality of the present geometrical satellite constellation under line-of-sight conditions, and (ii) at least one characteristic environmental parameter considered in the model independently of the DOP value and describing a local influence of objects on the propagation of GNSS signals. The method further includes step b) determining a location and/or a time at which location and/or time the GNSS geolocation quality is to be predicted. In addition, the method includes step c) determining at least one DOP value at a given time as a function of the location of the GNSS receiver provisionally determined in step b) and providing the DOP value as an input value to the model. The method also includes step d) determining at least one characteristic environmental parameter as a function of the location provisionally determined in step b) and providing the at least one environmental parameter as an input value to the model. Also, the method includes step e) calculating at least one quality parameter describing the quality of a GNSS geolocation using the model provided in step a) as a function of the parameters provided in steps c) and d).

A method is described for updating a digital map for vehicle navigation. The method includes a step of determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of the digital map to be updated, using an item of information about the area to be updated, and the method including a step of supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.

A method for determining an environment-specific data profile for a satellite-based determination of a position of a vehicle includes ascertaining the position of the vehicle and receiving satellite data. The environment-specific data profile is determined using the ascertained position of the vehicle, a satellite position of a satellite from the received satellite data, and a path length of a satellite signal between the satellite position and the vehicle position determined from the satellite data.
