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?
