Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government what assessment they have made of alternatives to the European Geostationary Navigation Overlay Service; when any alternatives would be operational; and what they would cost.

This Government recognises the importance of Positioning, Navigation and Timing (PNT) technologies for our security and prosperity. We are implementing the Government Policy Framework for Greater PNT Resilience, including developing proposals for a National Timing Centre and enhanced long-range navigation system. The Government is considering options for UK access to a satellite-based augmentation system (SBAS). This work is ongoing and no decision has yet been made.
