- 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
