摘　　要：对北斗双星基本型用户机在某地区进行了海上动态、陆上静态定位试验及其短信发报功能测试。试验结果表明:动态、静态定位精度基本一致;X 值(北纬度)变化幅度较大,Y 值(东经度)较为稳定;其定位精度可满足小于 1:25000 比例尺海洋测图;短信发报功能独特,几乎不受距离限制。研究指出可以运用北斗双星的短信发报功能来完成 DGPS 及北斗双星导航定位的差分信息,并提出了基于北斗双星/DGPS 组合导航定位的海洋综合测量系统的基本框架及功能设计。By using of tipper double stars system, experiment studies on land static positioning and marine dynamic position are conducted. The function of its message transmission is also tested. The experimental results show that the positioning accuracy is basically the same on land static positioning and marine dynamic position. The change range of x for positioning, north latitude, is rather big. And the , east longitude, is steady. It was concluded that the positioning accuracy could met the demands of marine surveying of 1:25 000 marine map. The messages transmission function is powerful. It is very important and practical value that the difference information of DGPS or dipper double star system are sent by the note function of dipper double stars system. The frame is put forward for marine synthetically surveying system based on navigation and positioning of combination of dipper double stars and DGPS system..
