  • In the case of specific observation time and place, the attitude measurement system was assumed in reference attitude, and the trace and time informations of one star could be calculated in advance.The actual movement trace and time information of star were made in accord with calculated trace by adjusting equipment base, and reference attitude was established.The output information of attitude measurement system was compared with reference attitude, and a static test method of high-precision attitude measurement technology was proposed and carried out.The system error of attitude measurement equipment was detected exactly, and the triaxial attitude information of system output was corrected.Calculation result shows that the mean-square deviations of heading angle, roll angle and pitching angle are 19.98″, 11.43″, 12.05″ respectively, the static test method can achieve the accuracy of arc second, and its precision is higher.
