南方cass官方的rtk技术讲解视频，原理讲的比较透彻，有想了解rtk动态测量技术原理的可以参考一下。

This standard has been developed by RTCM Special Committee 104 as a more efficient alternative to Version 2 in various documents entitled "RTCM Recommended Standards for Differential Navstar GPS Service, Version 2.x”. Service providers and vendors represented on the SC-104 Committee requested the development of a new standard that would be more efficient, easy to use, and more easily adaptable to new situations. The main complaint was that the Version 2 parity scheme, which uses words with 24 bits of data followed by 6 bits of parity, was wasteful of bandwidth. Another complaint was that the parity was not independent from word to word. Still another was that even with so many bits devoted to parity, the actual integrity of the message was not as high as it should be. Plus, 30-bit words are awkward to handle. This standard, Version 3, is intended to correct these weaknesses.

随着测绘新技术不断的发展壮大，测绘作业的方式也有了日新月异的变化。背负式移动扫描系统的出现，大大降低了外业作业的劳动强度，而且其测绘的精度也得到了明显的改善。文中主要以背负式移动扫描系统为研究对象，通过以近领域提取点云的方式，对扫描点云做精确的坐标比对实验。通过实验，该扫描系统的平面精度与高程精度均满足大比例尺地形图测绘的要求，并且在测绘效率上比传统技术得到了显著地提高。
