Physical height changes play an important role in the modernization of national/international levelling networks in the discipline of geodesy. This paper represents a software package, named PHCSOFT (Physical Height Changes SOFTware) which allows to compute and plot physical height changes from Global Geopotential Models (GGMs) based on a monthly interval GRACE (Gravity Recovery and Climate Experiment) satellite mission data. The software has the ability to plot time series of computed temporal variations of geoid heights as well as temporal variations of surface deformations in up component, rapidly. In this contribution, the performance of software was tested at a point in Greenland. Accordingly, PHCSOFT is an alternative software package with its algorithm that speeds up the computation of physical height changes using GGMs from three GRACE computation centers.

在大地测量学领域，物理高度变化在国家/国际水准测量网络的现代化中起着重要作用。本文介绍了一个名为PHCSOFT（物理高度变化软件）的软件包，该软件包可以根据每月间隔的GRACE（重力恢复和气候实验）卫星任务数据，从全球地势模型（GGM）计算并绘制物理高度变化。该软件能够快速绘制出大地水准面高度随时间变化的时间序列以及上升分量中表面变形的时间变化。在这一贡献中，软件性能在格陵兰岛的某个地方进行了测试。因此，
