In order to solve the problem of high computational complexity of the ambiguity in attitude measurement, a new attitude measurement method based on antenna configuration is proposed. In a certain range of measurement error, the antenna array for attitude determination is properly configured, the integer ambiguity of double difference carrier phase is determined by the constraint information of antenna configuration. Short-baseline and middle-baseline are used for coarse and precise attitude measurement. This method for aerocraft attitude determination does not need to solve the ambiguity. It avoids the use of complex ambiguity search algorithm and improves the speed of attitude determination, it is suitable for fast attitude measurement of aerocraft.
