Abstract

The algorithm of pseudophase measurements ambiguity resolution for GNSS-based attitude determination is considered. For attitude determination several antennas located on the object surface are used. In the process of ambiguity resolution additional information in the form of known distance between phase centers of antennas (base vector length) is utilized. The much more efficiency of developed algorithm in comparison with other algorithms is shown. There are results for comparative correct ambiguity resolution probabilities and computer time costs. The possibility of using the single-band and single epoch measurements for attitude determination is displayed.
