高精度全球卫星导航系统(global navigation satellite system
GNSS)定位成果一般在国际地球参考框架( international terrestrial reference frame,ITRF)下表达,但是中国测绘成果要求采用2000国家大地坐标系(China geodetic coordinate system 2000,CGCS2000),高精度速度场模型是实现两者转换的关键。目前大多研究没有考虑不同函数拟合方法在不同速度方向上的表现,也没有深入研究同一方法不同的参数设置对速度场构建的影响。因此,根据中国大陆地壳运动监测网(crustal movement observation network of China
CMONOC)的260多个连续运行基准站和中国境内及周边地区的90个国际GNSS服务站数据,基于张力样条函数法和克里金法,分别采用不同的参数设置构建了覆盖全国的1 mm级高精度速度场模型,确立了在东、北、天 3方向精度最高的3种方法,并用这3种方法构建组合速度场模型。将该模型应用于全国范围连续运行基准站的ITRF2014和CGCS2000坐标转换。研究结果表明,所建立的组合速度场整体转换精度为2.261 cm,单一方向分量的转换精度维持在1.3 cm左右,能实现中国境内大范围测绘成果厘米级精度的基准转换。
Objectives
2
High precision global navigation satellite system (GNSS) positioning results are gene‑rally expressed under the international terrestrial reference frame(ITRF)
but China's surveying and mapping results require the use of the China geodetic coordinate system 2000 (CGCS2000). High precision velocity field model is the key to achieve the conversion between ITRF2014 and CGCS2000. At present
most studies use a single method to build the velocity field model
without in-depth study of the impact of different parameter settings on the construction of the velocity field
and without discussion of the performance of different methods in different speed directions.
Methods
2
For this reason
based on the data of 260 continuously operating reference stations (CORS) of the crustal movement observation network of China (CMONOC) and 90 International GNSS Service stations within and around China
and based on the tension spline function method and the Kriging method. We use different parameter settings to build a 1 mm high-precision velocity field model covering the country
establish 3 methods with the highest accuracy in 3 directions of east
north
up
and use these 3 methods to build a combined velocity field field. The model is applied to the coordinate transformation of ITRF2014 and CGCS2000 of CORS nationwide.
Results
2
The research results indicate that the overall conversion accuracy of the combined velocity field is about 2.261 cm
and the conversion accuracy of a single directional component is maintained at around 1.3 cm
which can achieve benchmark conversion of centimeter level accuracy for large-scale surveying and mapping results in China.
Conclusions
2
Based on experiments
we conclude that constructing the optimal component velocity field and forming a combined velocity field through different methods can effectively improve the accuracy of the overall velocity field model and be further applied in practice.
