New technologies present new challenges to PNT - the RIN PNT Advisory Group Executive Committee meeting had a lot to cover at its 23rd May meeting.  

UK PNT Advisory Group (PAG) Chair Andy Proctor and PAG Secretary Guy Buesnel report on the committees wide-ranging discussions.

The PNT Advisory Group Executive Committee met last month online; the topics discussed include:
Advances in Quantum technologies for PNT
The rise of Artificial Intelligence
PNT in Automation/autonomous systems 
The role of PNT Standards or Guidance in improving systems or equipment resilience 
Developing a communications strategy for the committee
Improving committee participation and International Reach 
Forthcoming RIN Defence Seminar at Aerospace Bristol
Following up the recent LEO event
A review of PNT Advisory Group Activities

Defence PNT

An area focussed on was the forthcoming RIN Defence Seminar at Aerospace Bristol on 03 July.  The MoD wants to reconnect with companies and individuals in the Defence Sector on PNT matters. RIN and the Advisory Group has developed a one-day programme of talks and discussion to enable discussions and networking. The event is especially important given the recent news stories detailing how an inertial navigation sensor has undergone trials on a Royal Navy warship.

The Seminar’s focus will be on 
What is meant by "resilient PNT" and "assured PNT"?
How should threats and hazards be considered?
Development of requirements for defence PNT systems
Approaches to assessing risks at different levels from modules to integrated systems
Mitigation approaches and their relative/absolute effectiveness
Research and development challenges
Latest developments in PNT for defence applications

The programme will have presentations from MoD and DSTL personnel in the morning and two panel discussions in the afternoon session. The event moderator is the RIN PNT Advisory Group Chair, Andy Proctor


The talks will include: -
Keynote: Wing Cdr Mark Brammer, MOD
Briefing from Strategic Command, Space Capability Planning (SATCOM & PNT) - Al Harris, PNT Desk Officer
Briefing from DSTL on their activities - Rob Handley, Acting Chief PNT Scientist
Briefing from DE&S - Jonathan Wilson
Briefing from DSC on their activity - Stuart Snedden, Space Team, UK Defence Solutions Centre

The afternoon panel discussions will concentrate on “Threats and Disruptions” and “Systems Thinking/Infrastructure protection”.

Low Earth Orbit (LEO) PNT

The Advisory Group discussed how best to follow up the recent RIN LEO PNT Seminar. RIN hosted the event in March 2023 to encourage a discussion and debate, under “Chatham House rules”, to discuss the technical, value chain, resilience, and business model challenges of providing PNT services from large satellite constellations. The event centred around open discussion, independence, and the objective of bringing the challenges forward for debate. 
These challenges include frequency selection, orbit determination and prediction accuracy (noted by a few attendees as “hard for LEO”); concept of operation (doppler or time-of-arrival), and the integration with other, linked services (independence and interoperability). 
Of greater concern in the room was the lack of clear business models from most of the LEO PNT providers. That is understandable as companies are reluctant to expose their models in front of their competitors. But there was less clarity in the room about why someone would pay for additional PNT services from space.

Approximately 100 people attended in person from over 40 organisations, UK and beyond, spanning users, service providers, equipment manufacturers and government officials.

The Advisory Group noted that a follow up by RIN is needed as the one-day seminar attracted some very lively debate and argument and succeeded in highlighting several key areas where significant challenges remain.

“Standards damn Standards”

The role of standards or guidance in increasing the resilience of systems or equipment is being discussed with the PAG preparing a white paper in this area. Its author Ramsey Farragher had opened the paper up to contributions from the rest of the executive committee. 

RIN PAG Chair Andy Proctor outlined the evolving US IEEE P1952 standard and its focus on resilience levels.  He speculated as to whether this approach would succeed in adding value to the PNT community but also stated that there was a need for intervention, be it a standard, guidance or even a code of conduct.  An analysis of the US Resilience Conformance Framework would be part of developing the correct intervention.

The meeting noted it is necessary to help users assess their current levels of resilience – there is nothing available to support presently.  This links to the other PAG activity on if there is a need for a UK PNT test bed, which is being consulted upon. The “standards” report is nearly completed and the executive committee discussed whether an RIN event on standards to coincide with the release of the document, would be worth considering. 

This blog invites recipients to feedback to the RIN on if a seminar on PNT standards/guidance/best practice would be welcomed. Please contact RIN Communications and Events Manager Clare Stead at comms@rin.org.uk with any feedback

Ensuring better communications

The group Secretary Guy Buesnel also presented plans to develop a coherent communications strategy for the RIN PAG which could be widely used to achieve consistency and greater reach for the group, including keeping members on the mailing list up to date.

The Committee also unanimously decided to issue approve the admission of Mitch Narins FRIN to the PNT Advisory Committee Exec team.  Mitch has been a prolific contributor to the work of the RIN and to developing Systems thinking for achieving PNT resilience and in developing usable standards to improve PNT Resilience. Mitch was employed with the FAA for more than 26 years, becoming Chief Systems Engineer for Navigation Services. He is also an Adjunct Professor at George Washington University, a member of the editorial advisory board for GPS World, magazine, a member of the Corporate Faculty at Harrisburg University of Science and Technology, is a Fellow of the RIN and is now the Principal Consultant and owner of Strategic Synergies, LLC.  Mitch will bring a wealth of industrial and academic expertise to the committee as well as a US perspective on Resilient PNT affairs.
The PNT Advisory Group always welcomes suggestions and inputs on PNT matters, large or small. Feel free to get in touch. 

Andy and Guy.

PNT in the kitchen

Posted By Andy Proctor, 08 December 2022

In our inaugural event on the 1st November we hosted around 100 senior Positioning, Navigation and Timing (PNT) leaders from across industry, academia and government at the Royal Society to discuss where PNT is in the UK, where the group thought it needed to be and how to get there. The meeting was held under Chatham House rules. 



A primary keynote was given keynote on the economic benefits of resilient PNT to the UK. This reflected a hypothesis that ‘the UK can generate value and sustainable leadership from investing in resilient PNT, benefiting government, academia, industry and, ultimately, individuals.’ The London Economics concept paper that this is based on, which can be downloaded HERE, notes that the UK has significant economic value at risk to even a temporary outage of GNSS, with the road transport, emergency, and justice services, and maritime found to be most precariously positioned. 

The London Economics paper continues to assess that major critical infrastructure sectors across the economy remain insufficiently prepared to face the consequences of outages or disruption to satellite-derived time and position, and that backup systems mitigate against the economic value risk. 

A recommendation was made that additional work is needed to identify and rank mitigation strategies in order of priority based on strategic and economic factors, that these need to be funded to prove the concepts and that the sector itself should organise itself to present a coherent face to global partners and customers. 

This echoed the introductory talks which discussed success being delivered through three functions; [having the right] infrastructure, [putting in place the right] leadership and governance, and [having a pipeline of] skills. The latter being identified through the day as a red flag for all concerned. Examples of open PNT roles were given by delegates, validating the point.

The main focus of the day was two excellent panel sessions, the first focussing on UK strengths, the second being concerned with examples of success but where there is room for improvement. The organisers were aiming for interactive discussion, and this was achieved, with many points being made by the wide range of delegates. 

 

Some of the key messages and points made include: 
the ability to monetise PNT services is a challenge when competing against “free”1  with GPS. 
The role, if any, for better use of legislation, regulation, and standards in resilient PNT – this requires systems thinking and a market focus, moving away from silos that sometimes we fall into.
The afternoon panel discussed the important point of careers and heard from all panellists about the need to create skills and career pathways from academia [including further education, not just universities] into industry and then structure for CPD. 
Overall, a strong call for co-ordinated action, led by government, on skills to have a greater focus that has been given thus far. It was recognised that individuals will invest their own careers in sectors with high growth and consistent investment. A strong strategy and programme for PNT in the UK would provide impetus and confidence for investment across the ecosystem, arguably reducing government’s own commitment required as well as reducing risks for all stakeholders. 
There was a clear wish for collaboration, particularly on governance and skills. There was a recognition that a range of short, medium and longer term actions will be needed. There was a strong call for RIN to be more proactive, and support for RIN taking leading roles in these areas.  

Where the group saw the role of Government was an urgency to announce a strategy and associated governance and programmes. Such leadership and structure itself would build confidence and create/enable the conditions for industrial growth. There were several specific examples cited where the current lack of clear decisions is having real impacts on business decisions, with investment and skills going elsewhere, including overseas. Government leadership and targeted initial investments in R&D and skills, possibly infrastructure too, with a well-targeted legislative approach, would build confidence. This, in turn, would lead to increased investment across the sector, and from individuals wanting to invest their careers in PNT. 
 


There was some discussion on how to support and encourage Government towards strategy and programme announcements. The MoD was cited as a good example where high priority has been given to [resilient] PNT. The attendees also were briefed on US experiences and that a more visible public information campaign and a visible and high-profile champion for PNT in the UK could be helpful.

Overall, the key messages from the meeting are below
 

 

What therefore is the role of the RIN in PNT going forward? 

 

The RIN is a learned society and as such is very well-placed addressing long term thinking, strategies and providing input to setting goals with Government. There was a call for the RIN to be the voice of PNT and Resilient PNT in the UK which means not only “helping Government walk backwards over the bridge” but in building the bridge in the first place! The call for RIN to take a proactive and leading role in this way received wide and universal support. 

The PNT Advisory Group (PNTAG), a special interest group under the Technical Committee, was warmly welcomed as the place to coalesce the UK’s PNT thoughts and directions but on the condition that it does something and not becomes a YATS (Yet Another Talking Shop). To that end I, in my summing up showed the PNTAG’s plan of action: 

 

The immediate task for the PNTAG is to update this workplan2 to reflect the outcomes from the event and the community input. 

Next will be to act on the plan and show that the RIN can deliver on leadership, long term thinking, support our colleagues in Government and to provide advice/guidance to the sector. We agreed we will plan to hold a repeat event around the same time next year where we will track progress – holding ourselves to account! The enthusiasm in the room on the day certainly gave me confidence that the plan is achievable. 

To summarise and to channel one of the speakers’ comments a little, the takeaway for me is that for PNT in the UK, we have all the ingredients of success and growth, but need the recipe and hunger to cook the meal.  

Our job is to pull the recipe for resilient PNT together and create the hunger for its implementation.

 

I would like to end with a call offers to contribute to the various work streams – please do get in touch with me if you are able to support this work.
