Not quite. Google is using the Received Signal Strength from WiFi access points. Here, Locata uses Time-of-Arrival measurements, obtained through GPS-like signal processing. This kind of techniques (based on correlation of a spread spectrum signal) is much more accurate than what Google uses, although I doubt it reaches inch accuracy.
