## United Kingdom National GPS Networks

- Professor Terry Moore
- Institute of Engineering Surveying and Space Geodesy
- The University of Nottingham

## Maritime DGPS

- Nine maritime DGPS stations operate in trial mode
- Pending full validation of performance
- Two additional inland stations by end of 2001
- Complete land coverage
- Fill minor gaps in marine coverage
- Fully compliant with ITU-R and IALA recommendations
- Frequency changes due to take place 18-19 September
- European plan to improve interference protection
- Allow establishment of new stations
