Abstract
This paper proposes a new approach to calibrate positions of pseudolite antennas. The most significant problem of conventional method is the weakness to the change of cycle ambiguity values due to the cycle slips or lock losses. Once the cycle ambiguity values are changed, the measurements become unusable and we must re-collect corresponding channel's measurements from the beginning. This inefficient process makes it take too much time and effort. In this paper, cycle ambiguity can be eliminated epoch by epoch for every single carrier phase measurement by introducing the multi-antenna. Moreover, the number of calibration points can be reduced down to 3 by use of measurements collected at unknown positions. Using proposed methods, the process of collection of carrier phase measurements becomes considerably simple and comfort. Simulation results are presented to verify proposed algorithms.
