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 — each respective system’s usage of information provided by the other concept is not foreseen. This column examines GPS and Galileo integrity methods and proposes an algorithm for a combined integrity approach using data from both, as well as practical issues of implementation and computation of associated protection levels.
