Abstract
An extended Kalman filter (EKF) originally designed for precise point positioning (PPP) has been implemented using GPS broadcast navigation messages and SBAS corrections in conjunction with integrity algorithms originally developed for Advanced Receiver Autonomous Integrity Monitoring (ARAIM) to produce protection levels of less than 10 meters. A new method for handling fault detection and exclusion (FDE) without requiring full reinitialization of the EKF is introduced. This new method maintains low protection levels through FDE.
