Precise Location: Myth or Reality

Brought to you by The Location Group

When presented with location technologies or applications, most users’ first question is commonly “How accurate is it?”. Is this a meaningful question, can it be answered in the absolute and if so, what does it mean when we describe a positioning system as "accurate"?

About the event

When presented with location technologies or applications, most users’ first question is commonly “How accurate is it?”. Is this a meaningful question, can it be answered in the absolute and if so, what does it mean when we describe a positioning system as "accurate"? Plus importantly, does this mean the same thing as "precise"? These terms will be explored in terms of their meaning and implications, or lack of, on end user applications.

Kindly sponsored by CSR and taking place at their offices in Cambridge, this half-day event will seek to address the pertinent issues: How accuracy/precision requirements can be formulated, are these terms universal and how do they contribute to the value chain within which the application is participating?

The event will open with a review of the ever-increasing different satellite positioning systems and scrutinise their respective effective performances both outdoors and indoors. This will be followed by a survey of other techniques covering indoors context, where satellite positioning either works poorly or not at all, leading us towards the notion of fusing of different positioning techniques with the objective of position high availability.

From this point we will naturally address the important issues of selection of the methods and combination of the results, considering success criteria. Returning to the point of view of the applications, we will question the value or necessity to provide the nature of the selected solution and attempt to expose means of expressing confidence in the results.

Following this we'll consider what the terms accuracy and precision mean; how to interpret them and how to use them in applications. Latency will also be covered as accuracy and precision can probably be improved over a period of time. The usefulness of these techniques will have to be reviewed.

We will conclude by asking how accuracy/precision requirements can be formulated, are these terms universal and how do they contribute to the value chain within which the application is participating?

Explosion in Satellite Navigation; Dr Tony Pratt, Independent Consultant, Orbstar Consultants

There has been rapid growth in the number of providers of satellite navigation signals during the past 7 years or so. The providers now are the USA (GPS), Russian Federation (Glonass), European Union (Galileo), China (Beidou), Japan (QZSS), India (IRNSS, GINS). In addition to these primary navigation signals, there are also available a (growing) number of Space-based Augmentation Systems (SBAS) including WAAS, EGNOS, SDCM, MSAS and others. The presentation provides insight into the reasons for this growth, the satellite orbits chosen and the signals available from each. Innovation in the signal structure has encouraged considerations of greater accuracy, partly from the satellite position and clock accuracy, partly from orbit description and modelling and partly from the signal processing techniques in use. Which signals should be used and why? Perhaps, all should be used but this implies increase in receiver complexity. Is it worth it? The presentation will touch upon these critical questions for both the user and receiver designer.

Q&A

Behind the little blue dot; Dr Ramsey Faragher, Senior Research Associate, University of Cambridge

We have all become accustomed to the reliability of the little blue dot on our smartphone maps, and the fusion of satellite, cellular and Wi-Fi positioning systems mean that it is rare to find ourselves stuck without a position fix. But what started life as a casual navigation tool for vehicular navigation (benefiting from the assumption that snap-to-the-road algorithms correct the positioning errors) is now being squeezed for more and more performance. Your smartphone will soon confirm which supermarket aisle you are in, and will take you right to your seat at football matches and concerts. That level of accuracy requires a very careful appreciation of what is really going on behind the little blue dot, and mere assumptions have to be left at the door. In this talk we will look at the importance of confidence estimation in the design, implementation and delivery of indoor location systems and its role in providing improved performance, not just better error estimates, for the user. We will look at how system modelling and computational grunt can provide higher positioning performance than measurements alone can, and why app developers can only take their tools so far – the true capabilities lie with the chipset providers.

Industrial Indoor Location; Andy Ward, CTO and VP Engineering, Ubisense

Much of the recent interest in precision in-building location has focused on consumer-centric applications, but there are many uses for similar technologies in the industrial domain. In this presentation I’ll look at why the characteristics of indoor location systems for industrial applications often differ from those targeted at consumer applications, and why precise location is so valuable to industry.
