Infrastructure system for providing GNSS signals for the satellite-based determination of the position of a vehicle in an area with at least limited visibility of GNSS satellites

摘要

The invention relates to an infrastructure system (1) for providing GNSS signals for the satellite-based determination of the position of a vehicle (2) in an area (3) with at least limited visibility of GNSS satellites (4), comprising: at least one GNSS Receiver (5), which is assigned to the area (3) with at least limited visibility of GNSS satellites (4), but is arranged so that there is visual contact with GNSS satellites (4), - at least one infrastructure-side GNSS transmitter ( 6) to provide a modified GNSS signal for at least one vehicle-side GNSS receiver (7) in the area (3) with at least limited visibility of GNSS satellites (4), - an infrastructure-side evaluation unit (8), the GNSS data from which receives at least one GNSS receiver (5), converts them into modified GNSS signals depending on the respective relative position (Δs1, Δs2, Δs3) of the GNSS receiver (5) and GNSS transmitter (6) and nd outputs the modified GNSS signals to the at least one GNSS transmitter (6).
