The project is aimed at deveolping an element able to provide an additional integrity layer over the PPP corrections corrections generated to provide high-accuracy positioning services. The PPP Safety Processor is an enabling item for the provision of an Assured PPP Correction Service. The PPP Safety Processor will provide the following capabilities:

• Identification of GNSS threats or anomalous behaviours on GNSS signals and data

• Computation of error bounds associated to the PPP corrections.

• Computation of usability associated to the PPP corrections.
