The GLAs DGPS system is provided for maritime use. Implementation was completed in conjunction with Trimble Navigation Limited in August 1998 and the system will continue to operate in trial mode for a period. The GLAs will be validating the system thoroughly before declaring operational capability. Problems with DGPS receiver equipment should be taken up with the supplier, whereas users who experience problems with the system are invited to complete and return an Incident Report Form which can be obtained as follows:
