Zukunft der DGNSS-Aussendungen auf Lang- und Mittelwelle
Die "General Lighthouse Authorities of the UK and Ireland (GLA)" hat beschlossen, die Aussendung von DGNSS-Korrektursignalen auf Lang- und Mittelwelle zum 31.03.22 einzustellen.

Differential corrections are also available from other sources, including Satellite Based Augmentation Systems (SBAS), which are primarily provided for aviation users.
Work is under way in Europe to introduce a maritime service to EGNOS 5, the European SBAS.
This service is expected to be available around 2022.
It is important to note that today’s maritime receivers are not tested for how they apply SBAS data as that functionality is not part of the receiver standards today.
This is being addressed and those mariners wishing to take advantage of SBAS information in the future would need to upgrade their receiver to one that is type approved for SBAS use (expected 2022-23).
Future of the GLA DGPS network
After careful consideration of the results of the consultation process, recognising that today’s GNSS are able to meet all but the most stringent accuracy requirements, and that position integrity can be provided by alternative means (Receiver Autonomous Integrity Monitoring (RAIM) or by mariner’s validating their position via other visual and electronic aids-to-navigation), the GLA have concluded that their DGPS system is now redundant.
The GLA recognise the need to provide adequate notice and support continuity of service going forward.
As such, the GLA DGPS system will remain operational until 31 st March 2022, at which point the signals will cease.
It is recognised that while SBAS, such as EGNOS across Europe, should provide useful services to the mariner in time, there is no guarantee that they will come to fruition.
Similarly, it is anticipated that alternative sources of integrity will continue to improve as mariners move to multiple satellite receivers, with more satellites and signals available, and as RAIM algorithms advance.
The use of all available satellite constellations with advanced RAIM algorithms in the future is expected to provide greater positional accuracy and integrity than is available today with marine radiobeacon DGPS.

Meine Fragen:
1) Planen Sie ebenso, die Aussendung von DGNSS-Korrektursignalen auf Lang- und Mittelwelle mittelfristig zu beenden ?
2) Wie ist der konkrete Zeitplan hierzu ?
3) Unter
https://beacon-status.wsv.bund.de/cgi-bin/beacon-wsv.cgi
beschreiben Sie Ihr System zur automatisierten Überwachung Ihrer Aussendung von DGNSS-Korrektursignalen auf Lang- und Mittelwelle.
Planen Sie, dieses Monitoring System um eine automatische Überwachungseinrichtung für EGNOS 5 (European SBAS) zu erweitern ?
Vielen Dank.
