What’s a nanosecond between friends?

Brought to you by The Location Group

An event to review the state-of-the-art in clocks from the highest precision scientific devices to timing applications driven by cost and power. What is the implication of time on technology's future?

About the event

Robust time and synchronisation play major roles in positioning, from the high accuracy and precision required by GNSS satellites and LiDAR to radar, cellular positioning technologies and ultrasound ranging.

In the cellular world, successive technology generations have demanded stricter synchronisation amongst network entities. Maintaining accurate time to the edges of networks is one challenge, as is robust distribution in a network that may contain unknown or variable delays and attack threats is another.

Demands from financial services, broadcasting and power transmission are also challenging.
With the introduction of 5G imminent and connected autonomous vehicles on the horizon, how will the requirements for time accuracy and availability change?

We shall explore the implications of technological advances given by the exceptionally high accuracy of quantum and optical lattice clocks. We will also look at trade-offs between performance and size, weight, power, cost, robustness and environmental tolerances, including, for example, MEMS and graphene oscillators.

This event is kindly hosted by the National Physical Laboratory (NPL). The event is delivered by The CW Location SIG in partnership with The KTN and supported by UK5G

Kai Bongs - Professor, University of Birmingham

Patrick Gill - Co-Director, NPL Quantum Metrology Institute, National Physical Laboratory

Patrick Gill is a Senior NPL Fellow and co-Director of the NPL Quantum Metrology Institute, and heads up NPL Time & Frequency, where he is concerned with research into quantum frequency standards and atomic clocks and metrology, with wider application to fundamental physics, space science, satellite navigation and Earth observation, telecommunications, aerospace and defence.

Patrick joined NPL in 1975 after completing his DPhil thesis at the University of Oxford. He is a visiting professor at Imperial College and at the University of Oxford. He was awarded the Rabi Award by the IEEE International Frequency Control Symposium in 2007, and won the IOP 2008 Young Medal and Prize. His team received the 2014 Duke of Edinburgh award from the Royal Institute of Navigation for long term atomic clock development. Patrick was awarded an MBE for services to Science in The Queen's New Year's Honours List 2015. He was elected as a Fellow of the Royal Society in 2016. 

Bryn James - Senior Fellow, DSTL

Ashwin Seshia - Professor of Microsystems Technology, University of Cambridge

SIG Champions

David Bartlett - Senior Principal Engineer Positioning, u-blox UK

David Bartlett works in the positioning technology (R&D) group at u-blox with a focus on hybrid positioning: bringing together GNSS with terrestrial systems such as UWB and V2X, primarily in support of future autonomous vehicle, driverless car and robotics applications but also for IoT and indoor positioning. Prior to this he was CTO and co-founder of Omnisense delivering high precision indoor IoT tracking solutions. He also worked at Cambridge Positioning systems with a focus on cellular positioning and network aided GNSS techniques.

Bob Cockshott - Quantum Lead, PNT Lead, The KTN

After 25 years in the space industry working mainly on electro-optical payloads, Bob has spent the last 13 years in the government-funded Knowledge Transfer Network, supporting business in position, navigation and timing, and more recently also quantum technology. Bob has taken a special interest in GNSS vulnerability, and has organised international conferences on vulnerability and its mitigation. Bob is a member of the Cabinet Office PNT Technical Group and chairs the Royal Institute of Navigation’s Technical Committee. Bob is a member of the International Time and Sync Forum Steering Group and is also a Cambridge Wireless Location Based Services SIG Champion.

Ben Tarlow - Technical Marketing Manager, Qualcomm Technologies International

Ben has worked in positioning for 15 years, developing algorithms for satellite, cellular and other terrestrial RF technologies. At Qualcomm, Ben works in the Advanced Algorithms group, where current research areas in location are data fusion, use of sensor data for positioning and fitness applications; one day, he hopes to be given the remit to explore the area of olfactory positioning. Ben has a background in Pure Mathematics and a PhD in Combinatorics. He has over 20 different patents filed or granted, mostly on subjects relating to positioning.
