Digital detection technology is an important guarantee for modern aircraft digital manufacturing. At present, laser tracker is the main digital measurement system widely used in the aviation manufacturing industry, and the iGPS measurement system is a new large-size space measurement system. This paper focuses on Hanzhong Aircraft Branch, AVIC Aircraft Co., Ltd. using two kinds of digital measurement system for the process of comparative testing and engineering verification, at the same time, conducts a preliminary analysis of both measurement systems by comparing the results. It is concluded that the iGPS measurement system has some advantages over the laser tracker, but the networking accuracy and measuring accuracy are slightly lower, which is restricted by the number of engineering launchers and product structure, and the layout of the digital assembly system, and the measurement accuracy will be further affected. iGPS is more suitable for the digital measurement environment, where the accuracy of measurement is relatively low, the range of measurement is large, and the efficiency of measurement is required to some extent.
