Revolutionizing Navigation: UK SBAS Takes Flight

A groundbreaking test flight has showcased the capabilities of the UK’s Sovereign Satellite Based Augmentation System (SBAS). Conducted by Viasat, the flight demonstrated the system’s potential to enhance navigation across air, land, and sea. By providing precise positioning data and real-time corrections, the UK SBAS is set to revolutionize the accuracy of GPS systems.

One of the key advantages of the UK SBAS is its ability to offer positioning accuracy down to just a few centimeters, far surpassing the standard GPS accuracy of a few meters. For pilots, this means greater trust in their onboard instruments, particularly in challenging weather conditions. It enables pilots to approach runways with heightened confidence, even when visibility is poor. In fact, research conducted by Viasat reveals that up to 40% of flights cancelled due to weather conditions could have proceeded if the UK SBAS had been available.

Prior to Brexit, the UK had access to the European Geostationary Navigation Overlay Service (EGNOS). However, the departure from the EU meant that the UK would need to develop its own SBAS. The successful test flight marks a significant milestone in this endeavor.

The UK SBAS operates by generating an overlay test signal that is fully compliant with international aviation standards. This signal is broadcast in collaboration with the US Federal Aviation Administration, the European Space Agency, and the European Union Space Programme Agency. Viasat’s I-3 F5 satellite serves as the broadcast capability for the UK SBAS.

Following the aviation trial, the UK SBAS will be tested across other transport sectors, including rail, unmanned aerial vehicles, and autonomous road vehicles. The aim is to explore the full potential of this system and its applications in various industries.

Funding for the trial is provided by the Department for Transport through the European Space Agency’s NAVISP program. The project is led by a team of UK companies, including Goonhilly Earth Station, CGI UK, GMV, Ordnance Survey, Cranfield University, the Cranfield National Flying Laboratory Centre, and Pildo Labs.

The successful test flight of the UK SBAS represents a major leap forward in navigation technology. With improved accuracy and reliability, this system has the potential to transform the safety and efficiency of transportation systems in the UK and beyond. As the trial progresses, the future looks promising for this cutting-edge technology.
