Abstract National institute of metrology (NIM) has graded up the national small angle generator primary standard for automation. The graphically programming language- LabVIEW was applied in the development of measuring and control software of the system. The development realized the building block design with the modules of data acquisition of autocollimator and laser interferometer, control of rotary table, real-time data processing, data storing, and built a flexible programming frame. The system is utilized in the calibration of autocollimator and realized the automatic measurement with measuring range of -1 000″~+1 000″, and minimum measuring step of 0.1″, which satisfy the requirement of verification regulation and the international angle comparison using the autocollimator.
