Locata - Beyond GPS


Locata Corporation has collaborated with a number of research and industry partners during the development of this revolutionary technology. These partners have produced numerous independent conference papers and test reports on Locata technology, Locata prototypes, and their integration work. The University Of New South Wales (UNSW) SNAP group, in particular, has been working with Locata technology since 1999. Led by world-renown researcher Professor Chris Rizos, the UNSW have produced a large body of academic research papers, many of which are provided here. The documents below are in chronological order, starting with the very first paper published on Locata’s original technology prototype in 2003. This publication list will be updated as our partners produce new documents.
