Infrared beacon based sub-meter indoor localization

In this work a high precision sub-meter accuracy indoor localization system was developed using low cost infrared (IR) transmitters and receivers. With the help of the optical lenses and orienting mechanisms designed for the IR beacons, at about 0,75 m wide grid zone definitions could be achieved. An FPGA is armed for the evaluation of the data from multiple IR receivers at the mobile user. 0,5 m accuracy levels and 2 Hz update rates could be reached by this technique. After the test results, it has been shown that the system can reach the %88,3 precision level.
