A method for detecting a presence of interference during global navigation satellite system (GNSS)-based and inertial sensor signals (INS)-based localization of a vehicle includes determining localization results using a first filter configured to read in GNSS data and INS data, and storing a plurality of the determined localization results. The plurality of the determined localization results are after one another in terms of time and are each determined using the first filter. The method further includes analyzing the stored plurality of localization results using a second filter which differs from the first filter.

A method for detecting a standstill of a vehicle includes detecting the standstill of the vehicle using at least one sensor, and, when the standstill is detected using the at least one sensor, carrying out a test routine for checking the standstill of the vehicle. The test routine uses at least one signal from at least one rate-of-rotation sensor as an input value. The method further includes rejecting the detected standstill of the vehicle when the at least one signal from the at least one rate-of-rotation sensor indicates that there is no standstill of the vehicle.

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.

The disclosure concerns a method for providing GNSS sensor data, comprising at least the following steps: (a) receiving GNSS satellite signals; (b) evaluating the received GNSS satellite signals to ascertain GNSS sensor data; (c) rating the received GNSS satellite signals on the basis of at least one GNSS-specific performance criterion; and (d) associating a rating that results from step (c) with the related GNSS sensor data.

Method for providing GNSS sensor data

A method for monitoring an integrity of reference stations, having known and fixed coordinates, of a correction service system for a satellite-supported navigation system. A first group of the reference stations is operated to receive satellite signals of a plurality of satellites of the satellite-supported navigation system. It is provided that a) a first reference station is selected from the first group, and b) at least one first correction value is ascertained as a function of the satellite signals respectively received by the remaining reference stations of the first group, and c) the monitoring of the integrity is carried out in that first coordinates of the first reference station, determined using the satellite signals received by the first reference station and using the at least one first correction value, are compared with the known coordinates of the first reference station and checked for at least one first deviation.

A method for operating a correction service system (CSS), for a satellite navigation system (SNS), having reference-stations (RS) (in a coordinate-system (CS)) having known/fixed coordinates, the RS being operated to receive satellite signals, at least one correction-value (CV) being predefined as a function of the signals received by the selected RS and its coordinates, and is provided to user-devices of the SNS, the at least one CV being checked for plausibility. The CSS divides the CS into multiple-regions, in which user-devices determine an individual position as a function of the plausibility of the received CV, at least one specific-region being selected as a function of the plausibility of the CV, the specific-region(s) being assigned the at least one CV, at least one information-packet being generated, which contains indications about the plausibility of the CV and the specific-region(s), the information-packet(s) being provided to at least one selected group of user-devices.
