Abstract

A new method of GNSS gravity leveling is introduced to determine precisely normal height differences, Both the principle and application of the method are elaborated. Leveling surveying, gravity measurements, and GNSS measurements are carried out in a special region (including slopes, valleys and mountain ridges) to verify its accuracy by combining with gravity potential model. The results show that the precision by this method is mainly influenced by ellipsoidal height differences, gravity potential models, and gravity observations. However, the error by this method exhibits a clear linear relationship with the height difference, while it is independent of the length of the survey line. Within a specific range of height differences (within 360 m), the precision of the GNSS gravity leveling can reach the level of ± 10 mm. This method can, to some extent, provides a modern solution for height measurement which can replace the high-precision leveling surveying. The advantages of GNSS gravity leveling include high precision and high efficiency. It has a promising application prospect in geodesy, hydraulic engineering, earthquake and volcano monitoring.

全球导航卫星系统重力水平仪

介绍了一种精确测定正常高差的全球导航卫星系统重力水准测量新方法，并阐述了该方法的原理和应用。在一个特殊区域（包括斜坡、山谷和山脊）进行了水准测量、重力测量和全球导航卫星系统测量，通过与重力势能模型相结合来验证其精度。结果表明，该方法的精度主要受椭球高差、重力势能模型和重力观测数据的影响。不过，该方法的误差与高差呈明显的线性关系，而与测线长度无关。在特定的高度差范围内（360 米以内），全球导航卫星系统重力水准测量的精度可达 ± 10 毫米。这种方法在一定程度上为高程测量提供了一种现代化的解决方案，可以取代高精度水准测量。全球导航卫星系统重力水准测量的优点是精度高、效率高。它在大地测量、水利工程、地震和火山监测方面具有广阔的应用前景。
