Indoor Positioning System using Single Pseudolite with Multiple Antenna

C. Kim, O. Kim, T, Lee, C. Kee

Abstract:	In general, a number of well-placed (good geometry) signal transmitters are required to calculate user position. However, installing several transmitters is expensive and time-spending. In this paper, a new approach to calculate user position using single pseudolite and antenna array is described and evaluated. By use of carrier phase which is very precise, moderate user position error is obtained even under poor geometry. Cycle ambiguity is eliminated using closely placed transmit antennas. Some simulations are performed to verify proposed single pseudolite based navigation system. Even with carrier phase multipath, few meter level accuracy is obtained for both 2D and 3D positioning. Proposed system is cost effective, relatively precise, and robust to cycle clips, near far problem, and multipath.
