UK SBAS Testbed

Register for the Final Presentation of the NAVISP EL3-025 : "UK SBAS Testbed"

As the world moves towards greater levels of autonomy and automation, it is expected that wide-area safety systems and services will become the norm including both terrestrial and GNSS-based safety services. Other major developed economies in the United States/Canada (WAAS), Europe (EGNOS), Japan (MSAS), India (GAGAN), South Korea (KASS), and Australasia (SouthPAN) have now or will soon have access to high-integrity GNSS-enabled aviation procedures, largely implemented via Satellite-Based Augmentation Systems (SBAS).

Currently, the UK does not have access to such services, previously provided via EGNOS, for UK airspace flight operations. In this current situation, it is a priority for the UK to evolve national GNSS capabilities, implementing navigation and timing resilience and integrity, for (a) aviation, (b) maritime, and (c) other growing sectors using GNSS safety applications. As an important first step, there is a need to establish a UKSBAS testbed, broadcasting a GNSS Signal-In-Space (SIS) to begin to address the non-availability of EGNOS safety-of-life services.

The primary objective of the proposed UKSBAS testbed project, carried out by Inmarsat Navigation Ventures Ltd,  Goonhilly Earth Station Ltd, and GMV NSL Ltd, is to establish rapidly and operate a new national capability utilising current in-orbit Inmarsat geostationary (GEO) satellite assets, a navigation signal generator, associated SBAS data processing and monitoring software from GMVNSL, and use a UK ground station for SIS uplink from Goonhilly Earth Station (GES) to the GEO navigation transponder.

EL3-019 “UK SBAS Testbed" was funded by NAVISP Element 3, which is dedicated to support participating States in their national PNT strategies, promoting the development and promotion of GNSS and PNT products.
