In a method of improving the integrity communication in a satellite navigation system which comprises a space segment having multiple satellites which emit navigation signals for the reception and evaluation by use systems for position determination, and a ground segment having several observation stations which monitor the satellites, an error budget for different observation stations or groups of observations stations is transmitted with the navigation signal of a satellite. The navigation signal is received and an error budget contained therein is evaluated by computing a scalar value from the error budget. The scalar value indicates the precision of the error estimate for the generation of the navigation signal.
