摘要

Integrity as the measure of trust placed in the correctness of the information provided by navigation systems is clearly one key factor of safety critical applications.With the existing protection level concept employed by SBAS+ GPS and the computation of the integrity risk at the alarm limit used within the upcoming Galileo baseline integrity concept two different approaches will be available within the near future.Although both concepts share the same objective to describe the integrity of a user-and therefore have several basics in common-the usage of information provided by the respectively other concept is not foreseen. rnThe aim of this paper is a description and demonstration of a combined integrity algorithm using data from both integrity concepts.The algorithm is based on the provided integrity data available on the user side.Beside the algorithm itself also practical implementation issues and the computation of protection levels from calculated integrity risks will be presented.
