Enhanced Positioning Technique with QR Calibration

Author(s) : A.S. JA’AFAR


This paper describes an integrated positioning system that can be used for both indoor and outdoor navigation. The GPS (or any other system) in many scenarios is not sufficiently accurate especially for indoor. Even at a fixed location the accuracy is slightly changing with time due to signal propagation environment condition where current parameters do not reflect this. To address this, we propose a new criteria call “accumulated accuracy”. With this new parameter the GPS accuracy is estimated in a practical way using real data. In this paper, a sliding window technique is proposed for improving “accumulated accuracy” and it show improvement. In addition to this, the QR calibration is introduced for further improving the “accumulated accuracy”. This technique can also be applicable to various other positioning techniques.
