Method for providing GNSS-relevant route information

1 . A method for updating an availability map providing GNSS-relevant route information, comprising the following steps:

a) receiving GNSS raw data relating to at least one GNSS satellite signal;

b) evaluating the GNSS raw data;

c) forming at least one interference indicator for describing at least one interfering influence on the GNSS reception in an area of a geographic position and/or for a route section, taking into account the evaluated GNSS raw data relating to the area of the geographic position or the route section;

d) storing the at least one interference indicator with at least one item of geographic information on the area of the geographic position or on the route section; and

e) updating the availability map based on the at least one interference indicator and the at least one item of geographic information.

2 . The method according to claim 1 , wherein the GNSS raw data describes data that are output directly by a GNSS receiving unit.

3 . The method according to claim 1 , wherein a multiplicity of measurement runs is performed with measurement vehicles in order to receive the GNSS raw data.

4 . The method according to claim 1 , wherein, in the evaluation of the received GNSS raw data, at least one quality indicator is ascertained based on the GNSS raw data, and wherein the quality indicator is taken into account in the formation of the at least one interference indicator.

5 . The method according to claim 1 , wherein the formation of the at least one interference indicator is performed by a superordinate and/or off-board management system.

6 . The method according to claim 1 , wherein the at least one interference indicator includes a multipath propagation indicator describing a probability measure of an occurrence of multipath signal propagation in the area of the geographic position or the route section.

7 . The method according to claim 1 , wherein the at least one interference indicator includes an availability indicator and/or confidence indicator formed taking into account a probability measure of the occurrence of multipath signal propagation in the area of the geographic position or route section.

8 . A non-transitory machine-readable storage medium on which is stored a computer program for updating an availability map providing GNSS-relevant route information, the computer program, when executed by a computer, causing the computer to perform the following steps:

a) receiving GNSS raw data relating to at least one GNSS satellite signal;

b) evaluating the GNSS raw data;

c) forming at least one interference indicator for describing at least one interfering influence on the GNSS reception in an area of a geographic position and/or for a route section, taking into account the evaluated GNSS raw data relating to the area of the geographic position or the route section;

d) storing the at least one interference indicator with at least one item of geographic information on the area of the geographic position or on the route section; and

e) updating the availability map based on the at least one interference indicator and the at least one item of geographic information.

9 . A system configured to update an availability map providing GNSS-relevant route information, the system configured to:

a) receive GNSS raw data relating to at least one GNSS satellite signal;

b) evaluate the GNSS raw data;

c) form at least one interference indicator for describing at least one interfering influence on the GNSS reception in an area of a geographic position and/or for a route section, taking into account the evaluated GNSS raw data relating to the area of the geographic position or the route section;

d) store the at least one interference indicator with at least one item of geographic information on the area of the geographic position or on the route section; and

e) update the availability map based on the at least one interference indicator and the at least one item of geographic information.
