Quoted from International Mining
“Today (June 10) at the MassMin conference in Lulea, Sweden, Greg Baiden of Laurentian University, Canada (also Chief Technology Officer of Penguin Automated Systems) presented on a newly developed Underground Positioning System (UPS). The UPS has a range of some 2 km through rock and accuracy better than 3%. Mine trials are to be undertaken later this year and in 2009. Going forward, this has tremendous potential for finding trapped miners, for equipment mechanisation and mine wide asset management. The system employs VLF and would rely on a network of ’satellites’ placed to surround an orebody or underground workings.”
