I'm fairly new to the list and was going back through the archives to see if anything caught my eye. A Sept '07 discussion that started with a story on the US military giving up its right to turn off fairly accurate GPS signals (not a chance in my opinion despite what they say) then branched into talk of ground based GPS alternatives.
Thought I'd mention the work of an Australian outfit called Locata Corp which have been doing work in this area for a number of years. More info at http://www.gmat.unsw.edu.au/snap/publications/barnes_etal2003a.pdf . They keep a very low profile and part of the reason why I'm posting about this is to ask if anybody has any further info on these guys or similar?
