Personal and Indoor Positioning

The Personal and Indoor Positioning Theme addresses the significant engineering challenge of deriving position/navigation information provided in indoor environments which are unsuited for GNSS. 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.
