Background The UK Defence Science and Technology Laboratory (Dstl) is seeking information from suppliers regarding commercially available and proven Positioning, Navigation and Timing (PNT) systems capable of providing accurate timing and position information in environments where Global Navigation Satellite System (GNSS) services may be degraded, denied, disrupted or manipulated. The intended application is the provision of: 1. a highly accurate UTC-referenced timing signal, and 2. a static position solution to an external system operating in contested electromagnetic environments. This RFI is intended to identify mature technologies and assess the current state of the market. Responses will be used to inform future engagement and procurement activities. Please note: The Authority reserves the right not to undertake future procurement activities following completion of the RFI. 2. Required Capability 2.1. Timing Performance The system shall: • Provide a 1 Pulse Per Second (1PPS) output traceable to UTC. • Provide a 10 MHz frequency reference output. • Maintain a timing accuracy of better than ±30 ns relative to UTC. • Maintain timing accuracy during normal operation and throughout the required holdover period. 2.2. Positioning Performance The system shall: • Provide a static position solution with an accuracy better than 5 m relative to surveyed ground truth. 2.3. Holdover The system shall: • Maintain compliance with the timing and position accuracy requirements during a continuous 12-hour loss of all external PNT signal sources. 2.4. Resilience The system shall: • Continue to provide compliant timing and positioning performance in the presence of GNSS jamming and spoofing. • Be capable of acquiring and establishing an initial timing and position solution in the presence of GNSS jamming and spoofing. • Where non-GNSS PNT sources are utilised (e.g. LEO-PNT), the system shall demonstrate resilience to jamming and interference affecting those signal sources. 2.5. Technology Maturity The system shall: • Utilise proven technology with a Technology Readiness Level (TRL) of 9, or provide evidence of equivalent operational deployment and maturity. 2.6. Operational Environment The system shall: • Be capable of operating globally. • Identify any dependencies on antenna siting, sky visibility or supporting infrastructure. • State any environmental or deployment constraints that could affect performance. 3. Exclusions The proposed solution shall not: • Depend upon fixed local infrastructure such as fibre-optic timing distribution networks. • Require user-generated or user-provided PNT signals. • Depend upon temporary or ad hoc reference sources that are not persistently available. • Depend upon any ITAR-controlled components. 4. Information Requested Suppliers are requested to provide the information detailed below: • System Description - Overvie... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/request-for-information-resilient-timing-and-positioning-system-for-operation-in-degraded--ocds-h6vhtk-07b9ac) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planning - **CPV codes:** 38112100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Contract Period:** 04/02/2027 to 26/03/2027 ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F107427-2026) - **Last Source Update:** 2026-11-12T10:18:53.000Z - **This document generated:** 2026-11-14T12:58:48.510Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-07b9ac - **Licence:** Contains public sector information licensed under the Open Government Licence v3.0.
