Tech Track 100

This firm was the brainchild of Peter Duffett-Smith, an astronomer at Cambridge University. In his studies of distant galaxies, Duffett-Smith found that his radio telescope needed to be located precisely, to within a foot, or the error on his measurements would be too large. He designed a tracking system based on the distance between three mobile phone masts and tested it by tracking the position of his students as they walked the college grounds. This software is now licensed to network equipment vendors, handset vendors and chipmakers, including Intel. The company is backed by £38m from 10 venture-capital firms and, despite significant losses, its sales have grown 137% a year from £712,000 in 2000 to £4m in 2002.
