Part of the “Locata technology” consists of a time-synchronised pseudolite transceiver called a LocataLite. A network of LocataLites forms a LocataNet, which transmits GPS-like signals that allow single-point positioning using carrier-phase measurements for a mobile device (a Locata). The SNAP group at UNSW has assisted in the development of a Locata and testing of the new technology. In this paper the prototype “Locata technology” is described, and the results of indoor positioning performance test experiments are presented. The experiments demonstrate proof-of-concept for the “Locata technology” and show that carrier-phase point positioning (without radio modem data-links) is possible with sub-centimetre precision. ]]> LocataLite.pdf (3 MB)

We discuss the different components of the Horus system and its implementation under two different operating systems and evaluate the performance of the Horus system on two testbeds. Our results show that the Horus system achieves its goal. It has an error of less than 0.6 meter on the average and its computational requirements are more than an order of magnitude better than other WLAN location determination systems. Moreover, the techniques developed in the context of the Horus system are general and can be applied to other WLAN location determination systems to enhance their accuracy. We also report lessons learned from experimenting with the Horus system and provide directions for future work. ]]> horus_usenix.pdf (283 KB)
