中文摘要	The attitude angle of the space-stable system can not be measured directly from the frame angle. Instead, a series of computation is needed to realize the direct measurement. The paper deduced the solution equation of attitude angle of four-gimbal space-stable platform, and designed a high precision frame-angle measuring system which was the key system for attitude calculation. Based on these, the algorithm flow of attitude calculation was presented. The testing results show that this method can correctly calculate the attitude angle. If the velocity-damp and altitude-damp were introduced, the calculation precision could reach 20" by using a precise gyroscope drift model, which satisfy the requirements of high precision inertial guidance system.
