Aiming at the technical features of separate azimuth vertical transmission device, a new calibration method with high accuracy for different transmission distances is proposed. The measuring and calibration of azimuth vertical transmission are achieved in different transmission distances without me-chanical connection in horizontal state by using pentprism, silicon plate and auto-collimation theodolite. The error analysis and experimental verification of the calibration system are carried out. A theoretical ba-sis is provided for the promotion and application of azimuth vertical transmission device.%针对分离式方位角垂直传递装置的技术特点，提出了一种适合不同传递距离、高准确度校准方法。在水平状态下，利用五棱镜、硅油盘和自准直光电经纬仪，实现对不同传递距离无机械连接的方位角垂直传递装置的检测和校准，并对校准系统进行了误差分析和试验验证，为方位角垂直传递装置的推广应用提供理论依据。
