“Philipp Ronnenberg’s ongoing OpenPositioningSystem / openps.info is a very hands-on, concrete project that aims to offer an alternative to the dominant global positioning systems or other navigation systems which are controlled by governments, network companies or in the case of GPS by the U.S. military. These technologies are closed at the moment and can be shut down at any time.
“The idea is to use seismic frequencies, produced by generators in power plants, turbines in pumping stations or other large machines running in factories. These generators, machines etc. are producing seismic activity, distributed over the ground. The sensor prototype can detect seismic waves on the ground, walls or anything with enough contact to the ground.”
