摘要
随着GPS技术的不断发展和新技术的推广应用,现行规范中的一些技术指标已不再适应。本文阐述了GPS新技术RTK、PPK、PPP的工作原理,详细介绍了它们的技术特点,然后在不同地形地貌、使用不同的参数进行测量,并对测试结果进行了科学的分析和探讨,总结出了RTK、PPK、PPP技术在测量施工中满足施工精度的条件和基本的技术指标,以供修改规范参考。
Along with popularization and application of new techniques and constant development of GPS, the current technical specifications in standard are no longer appropriate. The paper expounded the work principle of RTK, PPK and PPP in new GPS technique, introduced in detail to the technical characters, then, carrying out measurement by using different parameters according to different geography, scientific analysis and discussion on tested results, then summarized the conditions and basic technical specifications of RTK, PPK and PPP that should meet operation precision in measurement operation, which gives a reference to modified the standard in future.
