|Abstract:||This paper investigates two techniques to reduce the computational load of running multiple fault tolerant Kalman filters in order to provide integrity. These approaches are then exploited in the implementation of a solution separation integrity monitoring algorithm in a PPP Kalman filter solution. We evaluate the techniques using GNSS data collected in static and driving conditions. In our scenarios, these techniques lead to computational load reductions of at least 70% at the expense of protection level degradations of about 50%.|
