Personal and indoor positioning

Pedestrian navigation includes personal applications such as for emergency service personnel inside buildings and the blind and visually impaired, using a range of sensor/positioning technologies, either on their own or in combinations, including WiFi-based positioning, RFID, vision and inertial sensors, and mobilephone-based positioning.

Locata is a high accuracy positioning technology that can be used on its own or in combination with GNSS. Locata is an Australian invention that has been described as a ‘local GPS’ because it can satisfy GPS performance requirements even where GNSS cannot operate, using terrestrial signal transmitters. Locata applications include precise indoor positioning, positioning in deep open-cut mines and in airborne applications, all scenarios where GNSS may be unavailable due to jamming or obstructed satellite signals. SNAP Lab researchers have played a significant role in the development and testing of Locata-based systems.
