We monitor all our active land and sea based Aids to Navigation from Edinburgh. The correct functioning of all active Aids to Navigation i.e. all those that transmit as part of their function, whether it be light, sound or radio signal, are monitored from Edinburgh giving improved system reliability and availability. The estate has over 300 such Aids to Navigation of which more than 203 are at present monitored including buoys using GSM and AIS. Land based lights are monitored using a PSTN, UHF low and high power radio, GSM and satellite with AIS also to be used in future. See below for description of AIS.
The monitored data is transmitted around the corporate computer network using the web and it can be viewed anywhere a connection is available.
