GLA Differential Global Positioning System (DGPS) Service DGPS Recapitalisation Works
24 April 2009
Date: Between the months of July 2009 and April
2010.
The General Lighthouse Authorities (GLA) have commenced
preparations for replacement and upgrading of the Differential
Global Positioning System (DGPS) equipment for the United Kingdom
and Ireland. This upgrading will allow differential corrections to
be transmitted for future GNSS and additional signals from existing
GNSS. There will be no changes to the broadcast parameters
(frequency, range etc.). The upgraded service will remain
unencrypted and therefore free to users with appropriate
receivers.
It is considered appropriate at this time to advise users of the
engineering works to upgrade the existing DGPS equipment.
The following DGPS broadcast stations will be upgraded between the
months of July 2009 and April 2010.
| England & Wales | Scotland | Ireland |
|
Flamborough Pt. Lynas North Foreland St Catherine's Nash Point Lizard Wormleighton |
Girdle Ness Stirling Butt of Lewis Sumburgh Head |
Tory Island Loop Head Mizen Head |
The programme of work has been designed to ensure no disruption of
the service to users. Individual stations will be taken off air for
periods during this programme. However, adjacent stations will not
be off air at the same time, thereby allowing the overlapping
coverage of the system to provide continued service within the
coverage area.
Broadcast station site specific works will be advised by use of a Radio Navigation Warning at least 48 hours prior to the commencement of works. Notification will also be broadcast by message 16 from adjacent DGPS stations.
By Order, S. G. R. Ruttle, Chief Executive.
Mariners are invited to contact the Marine Department, Commissioners of Irish Lights to comment on any aspect of the Aids to Navigation Service or on hazards to navigation around the coast of Ireland.
