SatNav – from GPS to Galileo, but under threat

Presented by Professor Malcolm D Macleod, MA, PhD, FREng, CEng, FIET, FIMA, SMIEEE

10 Apr 2024 /  
5:30pm - 7:00pm


This is an IET Coventry and Warwickshire Local Network Event.

Everyone is welcome.

GPS was the first global Satellite Navigation System; now there are four - why? To work they need to know the positions of many orbiting satellites accurately – why was such a challenging method chosen? Each satellite transmits lots of signals – what are they for? Receivers have shrunk from tall cabinets to handheld devices – but they are still challenging.

Malcolm will explain how smartphone SatNav uses tricks to work faster and save power. Then describe how the uses of SatNav have grown far more than was ever envisaged, making us now dependent on it. But SatNav technology has limitations – such as its limited accuracy and its susceptibility to deliberate interference. How new receiver technologies are combatting those will also be discussed.

Professor Malcolm D Macleod, MA, PhD, FREng, CEng, FIET, FIMA, SMIEEE

Professor - University of Strathclyde

After a PhD in DSP, Malcolm joined Cambridge Consultants as an engineer, then group leader and consultant; he also taught for Cambridge University part time. He was next appointed a full lecturer in the Signal Processing and Communications group at the Engineering Department of Cambridge University, and later the Director of Research for the department. He joined QinetiQ in Nov 2002, where he became a Chief Scientist (Research and Innovation) as well as a Senior Fellow and the Dean of the Fellows. In January 2007 he was appointed a visiting Professor at the University of Strathclyde. He has served on the organising committees of many EUSIPCO, IET and IMA conferences.

He has worked in digital signal processing (DSP), image processing, inference and mathematical analysis for over 35 years. He is an expert in several areas, including parameter estimation, signal analysis, adaptive filtering, beamforming and algorithm/architecture design. He is a world expert in frequency estimation, frequency-domain processing methods, and multiplierless DSP implementations. He has over 100 refereed journal and conference publications and many patents (including several in GNSS).  He has innovated highly efficient high performance real-time algorithms and architectures for GNSS receivers, as well as sensing, communications, radar, SAR, SONAR and magnetic sensing applications. Some of his signal detection and estimation, localisation and tracking algorithms have been applied in a commercial GNSS receiver and other commercial products. He led a study for ESA into future signals for the 2nd generation Galileo system. He made a major contribution to the design of the DSP architecture for the QinetiQ Q40 GNSS receiver IC, and to the DSP software algorithms in it.
