| 中文摘要: |
| 手持GPS精度究竟如何、在哪些工作中可以放心使用一直是相关专业人士十分关心的问题。文章通过试验对手持GPS接收机的读数稳定性、时段恒定性、性能一致性等进行了定量测试,并通过工程验证、分析的方式定量化地推导了人员环境、坐标系统转换参数、高程起算面差异等因素对定位精度的影响,得出手持GPS接收机的绝对定位精度及其在地勘工作中的适用范围。对实际工作有一定的指导意义。 |
| 英文摘要: |
| The precision of portable GPS receiver and which kinds of jobs it suitable for, both are the concerned focus of geologist and other related people. In this paper, on the basis of testing the reading stabilization, constancy of time, and the consistency of function etc. of GPS receiver, deducing the influence on the accuracy of personnel-environment, the conversion parameter of different coordination system, starting surface level with field conformation and analysis, the author concluded that the accuracy of portable GPS and its suitable application range for geological exploration. |
