| 摘 要： | 给出了在海上用全球定位系统(GPS)进行动态测量的数学模型及其精度.研究表明,采用伪距和载波相位组合模型进行海上动态定位,可以满足大部分海上定位的精度要求.用GPS和测深仪对海底三维坐标进行了动态测定,建立了海底数字地形模型,联机自动绘制出海底立体图和等值线图.试验证实,这种方法是切实可行的,并提出了建立区域海底数据库的设想.

| Abstract: | The mathematical models used in Global Positioning System (GPS) to make kinematic measurements are established and the kinematic survey accuracy is given. During offshore kinematic positioning, the pseudorange and carrier phase mathematical models can meet most of the demands in accuracy. The GPS and bathometer were used to make out the 3D coordinates of the sea floor. A digital topographical model is given and the 3D sea floor graph and the isogram can be drawn on computer. Application of the model proved that the method is available. |
