| 摘 要： | 分别探讨在绝对定位和相对定位两种模式下手持式GPS定位的稳定性,得出合理的观测时间长。通过不同时长的观测数据的对比分析给出：实时定位与长时间定位观测值之差在1m之内。手持GPS绝对定位的准确度即测量的结果与其真实位置符合程度非常高,能够控制在亚米级的范围之内。在卫星个数较多的情况下,实时定位的精度也能控制在亚米级的范围之内。利用单点定位系统误差改正模型,消除或减弱某些误差后能得到更高的精度,使得单点定位精度达到半米之内甚至更高。 |
| 关 键 词： | 定位精度 内符合精度 实时定位 误差改正 |

| Abstract: | The stability of handheld GPS positioning is discussed in two models: absolute and relative positioning.A reasonable observation time is long is drew.Throwgh different time comparative analysis of observational data can be obtained,real time positiony and long term observation of the difference between the values of 1 meter.Handleld GPS absolute positioning accuracy of the measurement results to its actual location can be controlled with the range of submeter level.While in multisatellite environment realti... |
