Air Traffic Control The Netherlands (ATC-NL) seeks your valued advice in order to prepare a sourcing strategy for a GNSS monitoring system that is suitable and matches the set requirements. For this purpose ATC-NL has published this market consultation on TenderNed and Tenders Electronic Daily (EU TED). Due to the use of GNSS in civil aviation ATS procedures, local GNSS monitoring is required by ICAO regulations. In concrete terms, this means that a GNSS monitoring system must be setup by each member State. In addition to ATS procedures, GNSS is also used in aviation for other CNS functionalities. In particular, the timing function of GNSS (GPS) is a source of time information to synchronize systems between each other. Furthermore, the GNSS location data is used in ADS-B out surveillance messages. In The Netherlands, DGLM has appointed LVNL (i.e. ATC-NL) as a delegated entity to perform the GNSS monitoring to fulfil the ICAO local monitoring requirements. Although spectrum monitoring is primarily a task for the national Telecom Agencies, the National Digital Infrastructure Inspectorate (RDI, formerly the Telecom Agency) indicated that LVNL is permitted to monitor GNSS signals in the context of the ICAO provisions. Therefore ATC-NL is looking into the possibilities for sourcing a GNSS monitoring system. For that purpose ATC-NL has prepared a Market Survey Questionnaire that is accessible through the TenderNed tender platform. Initially a solution for Schiphol Airport and possible future extensions to other Dutch airfields.
