One common procedure of this technique is to place two or more receivers at fixed locations (usually short distances apart) of the moving object. 2. Since the locations of the antennas are fixed, constraints (e.g., the distance between two antennas) may be formulated which can be used to increase the efficiency of the ambiguity resolution. In principle, the gain by using constraints results in a reduction of the potential ambiguity sets. Background Knowledge: 4. Ambiguity Validation After the determination of the integer ambiguities, it is of interest to validate the quality of the obtained quantities. There, the uncertainty of the estimated integer ambiguities is to be determined. How do we validate the ambiguity? • Ambiguity success rate For more information, please read p.247-248. 4.
