The UK Ministry of Defence (MOD) is currently engaged in an investigation into the deployment of eLoran technology

The UK Ministry of Defence (MOD) is progressing its Alternative Positioning, Navigation and Timing (Alt PNT) programme, with a particular focus on deployable Enhanced Long Range Navigation (eLoran) systems. The decision follows Alt PNT industry days in March and June 2024 and was announced via a Request for Information (RFI) on 20 September. The UK government last year set out a ten-point ‘policy framework’ to improve national PNT resilience, one of which was to develop proposals for a resilient, terrestrial and sovereign eLORAN system to provide back-up positioning and navigation.

In this area, Septentrio is a leader in Global Navigation Satellite System (GNSS) solutions, specialising in the provision of highly accurate positioning technology.Septentrio's M3 Pro+ GNSS board is a versatile OEM GPS/GNSS receiver board that combines more than two decades of Septentrio's innovative technology. The receiver supports multi-band and multi-constellation GNSS systems, including GPS, GLONASS, BeiDou, Galileo, QZSS, and more, providing top-notch positioning performance in a variety of environments!

The UK MoD RFI specifies that a contract will be awarded to develop the deployable eLoran network and looks to develop modelling capabilities to enable theoretical analysis and to inform the concept of use. In addition, the UK MoD plans to enhance national PNT resilience by providing a PNT service to the British Isles and its adjacent waters through the installation of two or more additional transmitters.

The UK MoD's RFI has clear requirements for the questions it wishes to answer, which translate almost directly into the RFP and contract language. These include that the system should include a minimum of three transmitters to allow for suitable receivers to demonstrate the system's position and time determination capabilities on-site; that the system should transmit signals that enable the receivers to achieve position and time accuracy consistent with the requirements of the defence platform; that the system should be able to operate with and without Global Navigation Satellite System (GNSS) access; that the system should be able to be transported in ISO containers; that the system should be capable of being assembled, initialised, disassembled, etc. by the smallest possible team.

In this context, Septentrio's products, such as the M3 Pro+ GNSS board, provide the technology and services required by the UK Ministry of Defence.The M3 Pro+ GNSS board features AIM+ anti-jamming and monitoring technology, which provides in-built protection in the event of jamming and spoofing attacks, which is critical for military and defence applications that require high levels of reliability and resilience. This is critical for military and defence applications requiring high reliability and resilience.
This is vital for military and defence applications that require high reliability and resilience.

In addition, the UK Ministry of Defence (MoD), in the MoD's Defence Science and Technology Portfolio published on 7 June 2022, expects to invest at least £6.6bn in R&D by 2026 to address Defence's capability priorities, achieve decisive UK technological advantage, enable Defence to understand the future, maintain sovereignty and critical capabilities, and balance challenge-driven research with exploratory research.

These initiatives and requirements of the UK Ministry of Defence (MoD) demonstrate the importance it places on enhancing the nation's PNT capability and its strategic planning in terms of technology development and national security. Through these investments and projects, the UK aims to ensure that its Armed Forces remain at the forefront of technology in response to the changing international security landscape.Septentrio and its products, such as the M3 Pro+ GNSS board, can be a key technology support in this strategic planning The UK is committed to ensuring that the UK Armed Forces remain at the forefront of international security.
