由航天部二五所与船舶总公司第七研究院第七二六所共同开发研制的“GGC-401A型河床断面测绘仪”,于5月16日—20日,在七二六所的浙江莫干山对河口水库试验站水域,进行了水上动态验收试验。来自航天部、船舶总公司等有关单位的领导和工程技术人员30多人参加验收试验,一致通过验收。 GGC-401A型河床断面测绘仪由水声回波测深、雷达测距、计算机实时信号处理绘图打字输出等部分组成。它随着水陆两用车的航迹,能实时精确地测量
The “GGC-401A Riverbed Profile Mapping Instrument” jointly developed by the Ministry of Space and the Seventh Research Institute of the Seventh Research Institute of the Shipbuilding Corporation of China on July 25 and 20, Moganshan Estuary Reservoir Experimental Station waters, the water dynamic acceptance test. More than 30 leaders and engineering technicians from the relevant departments of the Ministry of Aeronautics and Astronautics, Shipping Corporation, etc. took part in the acceptance tests and passed the acceptance tests. GGC-401A riverbed profile mapping instrument consists of acoustic echo sounding, radar ranging, computer real-time signal processing drawing typing output and other components. With amphibian tracks, it measures accurately in real time
