Abstract
GNSS signals are usually used for positioning, but some applications also use them to determinate direction, such as geography north. The attitude of a vehicle could be determined by using multiple short baselines. However, the measurement accuracy is limited by the length of the baseline, so it also limits its application. This paper demonstrates an attitude determination method using GNSS Signals Null Steering (GSNS) technology by a miniaturized phase controlled antenna array. The error of DOA estimation is simulated and analyzed under the condition of received signal’s amplitude quantization error and the radiation patterns of antenna cells are inconsistent. The results show that the method has certain engineering feasibility.
