GAARDIAN
2008-2010
The GAARDIAN project successfully created a data gathering system, which can be used in the vicinity of mission/safety critical activities to analyse and assess the accuracy and reliability of Positioning, Navigation and Timing (PNT) including Global Navigation Satellite Systems (GNSS), e.g. GPS and eLoran.
The project covered:
- Comparison of GPS and eLoran signals in order to detect the existence of an anomaly, and the incorporation of a third timing reference of opportunity or a local atomic clock for anomaly identification
- The development of innovative signal quality monitoring algorithms for GNSS and eLoran signals
- Autonomous, adaptive data gathering sensor equipment design
This project reflected the increased need to integrate multiple navigation systems for greater accuracy, availability and integrity monitoring. We see this integration as the future for radionavigation, where the weaknesses of any one system are overcome by the strengths of others: the synergy of the whole is greater than the sum of its parts.
The GLA was one of a number of consortium members on this £2.2M project.
