摘要
讨论了差分全球定位系统 (DifferentialGlobalPositioningSystem ,DGPS)的系统构成及各种数据通信链路情况 ,系统分析了DGPS的各种误差因素影响的程度 ,采用计算机实验数据处理方法比较了 2D定位模式和 3D定位模式的定位结果 ,表明了在用户不经历任何大于± 5m的垂直运动的场合下 ,采用高度约束的 2D定位模式定位 ,其定位误差和 3D定位模式的水平位置定位误差具有同等趋势和量级。
The construction of DGPS, its data link, the various errors and their contribution are analyzed fully in this paper. The error situation of 2D positioning mode and 3D positioning mode is compared by the experiment simulation, it is presented that the horizontal positioning error of 2D positioning mode is at the same level and tendency to that of 3D positioning mode with the user vertical motion less than ±5m.\;
