PROVISION OF INFORMATION WITH RESPECT TO GNSS

Service providers of satellite-based augmentation systems should be considered as CNS providers within the scope of Regulation (EU) 2017/373, hence they should be duly certified. The ESSP has been certified and is overseen by EASA; as such, this provider is obliged to comply with the requirement in ATM/ANS.OR.B.005(f) in Annex III and to conclude appropriate agreements with the air navigation service (including air traffic services) providers concerned. Currently, these arrangements are stipulated in accordance with Section 9.3 of Attachment D to ICAO Annex 10, Volume I. When these arrangements are established, the ESSP provides information on the availability of its services to the relevant air navigation services providers.
