Cambridge back on track after $32m investment

NEWS CPS develops technology to track the locations of mobile phone users, using the Enhanced Observed Time Difference method, which estimates the distance between a user and a base station by estimating the time taken for the phone signal to travel back and forth. The company claims to be able to locate users on GSM networks to within 50 metres using trial installations of the system, which has not been made commercially available. The VC funds of Ericsson and Intel join Siemens' Mustang Ventures and a group of smaller VC players such as 3i, Alta Berkeley, and Argo Global, who participated in earlier funding rounds.
