“…These techniques have so far mostly been used to provide high accuracy, and it is only recently that they have been proposed to provide integrity, that is, position error bounds with a very low probability of exceeding them. There has been preliminary work [2] on the application of integrity to PPP, but it remains a challenge to translate the benefits of PPP to accuracy while maintaining high integrity. Most of the integrity work in PPP and RTK has dealt with the ambiguity resolution process under nominal error conditions [3], [4], and less on the integrity of the position solution under fault conditions.…”

UAV and autonomous platforms can greatly benefit from an assured position solution with high integrity error bounds. The expected high degree of connectivity in these vehicles will allow users to receive real time precise clock and ephemeris corrections, which enable the use of Precise Point Positioning techniques. Up to now, these techniques have mostly been used to provide high accuracy, rather than focusing on high integrity applications. In this paper we apply the methodology and algorithms used in aviation to determine position error bounds with high integrity (or protection levels) for a PPP position solution.

“…Precise Point Positioning (PPP) offers high accuracy, global positioning, and there is growing enthusiasm for the application of PPP techniques to safety critical systems [1], [2]. We have shown that PPP, in conjunction with techniques developed for integrity in aviation, can be used to produce meter-level protection levels for static, automotive, and flight scenarios [3].…”

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.
