GNSS Data as Court Evidence: Lessons from Remote Sensing

Andrew Dempster

Abstract:	For an expert witness providing comment on GNSS data, there is very little guidance in the literature regarding quality and admissibility of evidence. Conversely, the remote sensing community has developed quite a significant body of work. This paper examines firstly where and how GNSS data evidence can be compromised, and how a court can be informed of potential problems. Some of these problems are generic to the discipline of digital forensics, some are specific to GNSS, and some share characteristics with other methods of sensing. The various methodologies applied to remotely sensed data evidence are then examined to see where ideas can be readily transferred, and where new approaches are required.
