Device for measuring gyrotheodolite based on astronomical azimuth angle

WEI Chun1,HUO Bao-hua2,JIA Qian-lei1,TIAN Bao-ming2(1.Guangzhou Institute of Measuring and Testing Technology,Guangzhou 510030,China;2.The First Geodetic Surveying Brigade of SBSM,Xi’an 710054,China)  
To solve the problems of calibration and/or verification traceability and performance evaluation,a new gyrotheodolite measurement device was designed with the high-precision astronomical azimuth angle from astronomical measurements as reference standard.The device can measure and evaluate the orientation error and instrument constant.The long-term experiments and measurements show that the device has some characteristics such as simple structure,small footprint,stable data,excellent operability,few-personnel need,and so on.Thus the device has a certain prospect of popularization and application.
