Paper Abstract
A precision spatial measurement network for EAST was studied and established base on the EAST configuration and Laser Tracker system. 34 fiducials in outside network and 64 fiducials in inside network were united in one cylindrical coordinate by a laser tracker system. Unified Spatial Metrology Network (USMN) analysis showed that the single point average uncertainty of this measurement network was about 0.2mm, which can meet the measurement accuracy requirements of EAST. A combination measurement method with a laser tracker system and measurement arm was used for the assembly process of EAST device and some researches of environmental temperature influence have been done to improve the measurement process.
