Grant QuixleyRevitalizing Satellite Navigation in the UK
In a groundbreaking initiative, the European Space Agency (ESA) has partnered with satellite firm Viasat to launch advanced satellite-based augmentation services (SBAS) in the United Kingdom. This project comes at a pivotal time as the UK has been without these crucial safety services since leaving the European Union in 2021, which impacted the availability of essential landing approaches at major airports.
The UKSBAS testbed project, propelled by Viasat following its acquisition of Inmarsat Navigation Ventures, aimed to leverage existing Inmarsat satellites. Advanced navigation signal generation equipment, developed with GMV NSL, was employed to ensure a smooth delivery of services. A dedicated ground station located at Goonhilly Earth Station facilitated the necessary signal uplinking.
During the project, which spanned two years, numerous live trials were conducted within the realms of maritime and aviation navigation, as well as across various transport scenarios. Results presented by Viasat highlighted that the testbed had achieved performance standards comparable to established SBAS like EGNOS, maintaining high levels of accuracy and availability.
Moreover, the project introduced dual-frequency multi-constellation services, showcasing a remarkable enhancement in performance over traditional systems. Looking ahead, Viasat announced plans for implementing additional SBAS payloads by 2028, which will extend global navigation coverage. This initiative marks a significant leap forward in the future of satellite navigation in the UK.
