This report describes a low cost indoor position sensing system utilising a combination of radio frequency and ultrasonics.U sing a single rf transmitter and four ceiling mounted ultrasonic transmitters it provides coverage in a typical room in an area greater than 8m by 8m. As well as finding position within a room, it uses data encoded into the rf signal to determine the relevant web server for a building, and which floor and room the user is in.I t is intended to be used primarily by wearable/mobile computers, though it has also been extended for use as a tracking system.
