摘要
GPS技术的发展,特别是厘米级似大地水准面的发展,为GPS测量正常高提供了技术基础,然而把GPS测量大地高转换成正常高仍存在多种方法的优选问题。本文就GPS测量大地高转换成水准高的精度问题进行分析,给出了精度评定的具体方法,并提出四项提高GPS水准精度的具体措施。
The development of GPS technology, especially the development of quasi-geoid with centimeter accuracy,provides the basic technology for evaluating the normal height with GPS. But which method is the best should be studied further. The paper will deal with the problem in detail. In this paper, GPS geodetic height into a high standard of precision analysis, and gives the specific method of precision evaluation, and puts forward four measures to enhance the GPS level precision.
