摘　　要：提出了一种新的船载激光测距仪动态测距精度检测方法,通过地面固定激光合作目标和船载全球卫星导航系统(Global Navigation Satellite System,GNSS)接收机组成动态基线,采用GNSS事后动态精密单点定位获得高精度的动态基线,进而实现船载激光测距仪动态测距精度检测。利用船载实测数据对该方法的有效性进行验证,结果表明:GNSS动态精密单点定位精度可达到11 cm,能够实现米级船载激光测距仪测距精度的检测。A new method for the dynamic precision detection of shipborne laser rangefinders is proposed.The dynamic baseline is composed of the ground fixed laser cooperative target and the shipborne GNSS(Global Navigation Satellite System)receiver.The highprecision dynamic baseline is obtained by the kinematic postprocessing GNSS precision point positioning,and then the dynamic ranging precisise of shipborne laser rangefinders is detected.The method is verified by the data of onboard measurement.The results show that the dynamic precision single point positioning accuracy of GNSS can reach 11 cm,which can realize the detection of ranging precision of meter level for the shipborne laser rangefinder.
