摘　　要：针对传统罗经安装或校准测量方法操作复杂、耗时长、投入大,且不适用与船舶浮动状态下船艏向测量的缺点,提出采用星站差分GPS测船艏向的方法。工程实例表明,星站差分GPS测艏向的方法适用于专业海洋调查船的罗经安装与罗经校准值的获取。Considering that the traditional surveying method in installation and calibration has the disadvantages of complicated operation, long timing, large investment and not available for measuring the heading of vessel while the vessel is being float, the paper introduces the satellites chain differential GPS to get the heading of vessel. The engineering instance shows that, the way of satellites chain differential GPS can be used in installation and calibration of gyrocompass in professional marine surveying vessel.
