Aiming at the characteristics of the combination of the measurement control and the data transmission in the satellite monitoring and control network, the spacecraft-station iteration measurement technology is proposed to improve the measurement accuracy of the spacecraft. Based on the study of the star network model and the related measurement error analysis, the iterative measurement principle of the satellite station and the whole network iteration measurement process are described in detail. The calculation results of the iterative measurement are verified by computational simulation. The experimental results show that using the iterative measurement technique, the accuracy of the direct measurement results is improved by about 55%.
