Error and integrity evaluation during a position determination, includes: recording position values (P, P, P) and calculating clock errors of a receiver via time-discrete runtime measurements by a satellite navigation system; recording a first pseudo-distance at a later time via time-discrete runtime measurement by the satellite navigation system; extrapolating a position value (P') of the receiver at the later time and extrapolating a clock error of the receiver at the later time; establishing a distance (r′) between the extrapolated position value (P′) of the receiver and the position of a satellite (S) of the satellite navigation system at the later time, wherein a quality measure for the usability of the position determination with the satellite is obtained by forming a second pseudo-distance based on the sum of the established distance (r′) and the extrapolated clock error at the later time and comparing the second pseudo-distance with the first pseudo-distance.
