Space-Based Time Transfer Service (Space BaTTS) Research & Development

Description

The UK Space Agency (UKSA) intends to commence a competitive procurement for the delivery of concept studies to explore potential technical and commercial approaches for the provision of a space-based time transfer capability that is independent of Global Navigation Satellite Systems (GNSS). The requirement is part of the Space-Based Time Transfer Service (Space BaTTS) Research & Development Programme to develop, validate, and assess technology concepts that could fulfil an unmet government requirement for GNSS-independent global timing, provide UK overseas territories with backup timing solutions, and provide the UK mainland with an additional layer of timing resilience. The procurement will seek to appoint multiple suppliers to undertake time-limited proof-of-concept studies, to examine the viability of different space-enabled architectures and services to meet the aims of the Space BaTTS R&D Programme. Each study will assess technical performance, operational suitability, delivery risk and indicative costs, and will provide evidence to inform future investment decisions. The outputs will be used to develop a clearer understanding of the solution space and reduce uncertainty, informing any subsequent phases of work which could be undertaken.
