Do we need an open source GPS alternative?

Computer Weekly - Although occasionally infuriating around roundabouts and new developments, we have placed an inordinate amount of faith in Global Positioning System (GPS) satellites as they exist for in-car and/or smartphone usage.

So why would we need an open source alternative?

Well the GPS system was created and is still predominantly run by the US Department of Defense (they mean Defence) with a history that dates back as far as the early 1970s.

The US authorities have been accused of 'degrading' the system from time to time (presumably to suit their own needs) and alternatives have surfaced from the Next Generation Operational Control System (OCX) to Russia's Global Navigation Satellite System (GLONASS) system.

But British design student Philipp Ronnenberg believes that now the time is right for an open source version on GPS based on seismic ground vibrations.
