1. A method for GNSS-based localization of a vehicle, comprising:
receiving a first set of satellite orbit data at a first time;
using the first set of satellite orbit data to determine a first localization result;
receiving a second set of satellite orbit data at a second time that is subsequent to the first time;
checking a plausibility of the first set of satellite orbit data by comparing the first set of satellite orbit data with the second set of satellite orbit data, the plausibility check being unsuccessful if the first set of satellite orbit data is inconsistent with the second set of satellite orbit data; and
manipulating the first set of satellite orbit data, the first localization result, and/or a localization filter when the plausibility check is unsuccessful.
