Recently, an Immarsat led team of companies in the UK
Began the broadcasting satellite navigation signal.
This was done in coordination with the U.S. Federal Aviation Administration (FAA), the European Space Agency (ESA) and the European Union Space Programme Agency (EUSPA).
And was intended to explore the national capability in resilient PNT.
The UK Space-Based Augmentation System (UKSBAS) generates an overlay test signal to the U.S. GPS to increase the accuracy of positioning.
This is a significant development as the UK is no longer the part of Galileo system,
And cannot use European Geostationary Navigation Overlay Service (EGNOS) safety of life (SOL) services.
The tests will assess whether UKSBAS can develop into a full operational capability to support safety-critical applications in aviation and maritime sector.
And may be a step forward towards full-fledged UK GNSS?
