In recent years, due to the development of precise point positioning (PPP), the inconsistency of map and satellite positioning results due to crustal deformation has come to the surface. In order to solve this problem, a parameter for correcting the crustal deformation is necessary, and if it is provided as a service, the validity period and the accuracy guarantee are also necessary. In this research, we considered the validity period of parameters and the estimation method of the coordinates used for calculating the amount of crustal deformation and actually constructed the crustal movement correction parameter generation system and accuracy evaluation system. The parameters generated by this method are called semi‐dynamic reduction (SD/R) parameters. As a result of evaluating the accuracy of SD/R parameters, we achieved a target accuracy of 4 cm at 98.3% verification points in the horizontal direction. Therefore, the effectiveness of the proposed method was shown.

考虑有效期和精度保证的地壳运动校正参数的生成

近年来,由于精确点定位(PPP)的发展,由于地壳变形而引起的地图和卫星定位结果的不一致已经浮出水面。为了解决该问题,需要用于校正地壳变形的参数,并且如果将其作为服务来提供,则还需要有效期和精度保证。在这项研究中,我们考虑了参数的有效期和用于计算地壳变形量的坐标的估算方法,并实际构建了地壳运动校正参数生成系统和精度评估系统。通过这种方法生成的参数称为半动态还原(SD / R)参数。由于评估了SD / R参数的准确性,我们在水平方向上的98.3%验证点上实现了4厘米的目标精度。因此,表明了所提方法的有效性。
