摘　　要：精确确定点位坐标以及直线方位,可用于测定陀螺仪常数、雷达标校目标的位置及标定有关设备的真北方向等。利用GPS载波相位观测技术获取基线的方位角,重点探讨短基线整周模糊度的可靠性检验及大地方位角的计算方法;根据某雷达研制基地需要,建立了方位基准场。精度分析和实际应用表明该方位基准场达到了设计要求。Accurate point coordinate and its azimuth can be used in gyroscopes constant determination, radar target location as well as other equipments calibration. In this paper, GPS carrier phase observation is used for the short baseline azimuth determination, then we focus on the reliability test of the searched integer ambiguity about short baseline and the method of calculating the earth azimuth. In order to satisfy the requirements of a radar research base, a standard azimuth base is established, precision analysis and practical application demonstrate that it meets the design requirements.
