The article focuses on London event, which is organized to develop global navigation satellite systems (GNSS) in Great Britain and the Rail Safety & Standards Board, was the first major forum to bring together rail industry heavyweights and the wider satellite technology community. The results of two trial projects designed to test GNSS in the rail environment were outlined for the first time, offering a mixed picture of its effectiveness. One was a 25-week trial of the accuracy of GPS operating on a high-speed train running between London and the west country and South Wales. It involved space software specialist SciSys and rail engineering group Parsons Brinckerhoff, with the support of the British National Space Centre.
