Digital measurement technology and system are the important component of modern digital technology in aircraft assembly

which is applied in the assembly process of modern aircraft

not only ensure the accuracy of aircraft assembly

but improve the production efficiency

the full digital transmission is achieved from part design and manufacture to assembly process of aircraft products simultaneously.Several digital measurement systems are studied

which are widely used in aircraft assembly currently including laser tracker measurement system

three-dimensional laser scanning system

digital camera measurement system and indoor GPS system

the working principle and characteristics of the system are described and its application in aircraft assembly is discussed. According to the requirement of developing the digital assembly technology in the domestic

the application of digital measurement technology and system is prospected.
