Dear Marek, dear Mahesh, 

as a task leader Marek asked a few questions to committee members about progress on AIS AtoN in their countries/administrations:

1. How many buoys and beacons are fitted with "traditional" monitoring system in your country/admin? 
2. What type/types of monitoring is it (ex.VHF,GSM etc)? 
3. Are you planing to transmit their position info of them via base station(s)?If yes what number/percentage? 
4. What percentage of all AtoN in your country do you think should be seen on ECDIS as fitted with AIS? 
5. How many AtoN are fitted with AIS transponders in your country/admin? 
6. In what situations do you think virtual AIS shoud be used?-should be any restrictions/limitations? 

I couldn't achieve consolidated answers for Germany at short notice, so only the technical facts: 
1. There are about 20 buoys fitted with "traditional" monitoring systems. 
2. Type of monitoring: Most of them with GSM (Pintsch-Bamag "Codesy" and Sabik, some of them include the functionality of sequential and synchronized lights on buoys), 1 with satellite (Orbcomm), 1 more might be fitted with INMARSAT. 

3. and 4.: depending on requirements 
5. Yet there are no AtoN fitted with AIS in our country. 
6. no consolidated answer... 

Looking forward to meet you in OBAN 
Best wishes and regards 

Hendrik
