Abstract
A method for providing time information in a GNSS receiver includes receiving at least one time counter variable from a GNSS satellite. The at least one time counter variable describes a number of time intervals that have passed since a time start value, and a data length of the time counter variable limited to a maximum number of countable time intervals. The method also includes reading an offset variable out of a non-volatile memory held in the GNSS receiver. The offset variable describes a time previously received and reconstructed by the GNSS satellite, and a data length of the offset variable exceeds the data length of the time counter variable. The method further includes carrying out a remainder division of the offset variable with a maximum number given by the data length of the at least one time counter variable in order to determine an offset time counter variable.
