Integrated nearly 20 years of geodetic research results, the large scientific computing window platform for geophysical geodesy have been independently developed by Chinese Academy of Surveying and Mapping, which is composed of PAGravf4.5 (Precise approach of Earth gravity field and geoid) and ETideLoad4.5 (Earth tide, load effects and deformation monitoring computation). Based on the purpose of public welfare, the scientific computing platform is committed to improving the scientific research and higher education environment lacking in such computing resources in the geoscience field, showing the attractive potential of geodesy, reconstructing the heterogeneous geodetic system and collaborative geodetic frame, improving the geodetic ability in solving practical problem by multi-disciplinary collaboration, and supporting the deep fusion of heterogeneous Earth observations and collaborative monitoring of multi-geotechnologies.

The two software packages were developed by QT C++ (Visual C++) for the user interface, Intel Fortran (Fortran90, 132 Columns fixed format) for the core function modules, and mathGL C++ for the geodetic data file visualization in the Visual Studio 2017 x64 integrated environment. PAGravf4.5 is composed of nearly 50 win64 executable programs with more than 500 function modules, and ETideLoad4.5 is composed of more than 50 win64 executable programs with nearly 600 function modules.
The scientific computing platform is suitable senior undergraduates, graduate students, scientific researchers, and engineering technicians in geodesy and geophysics, geology and geoscience, geomatics and geographic information, seismic and geodynamics, aerospace and satellite dynamics. You can design your own schemes and processes, then organize flexibly the related programs and functions, perform the scientific computations for geophycical geodesy.
There are the example files saved in the folder C:\PAGravf4.5_win64en\examples and C:\ETideLoad4.5_win64en\examples for each Win64 program, espectively. Each example includes the operation process file process.txt, some input-output data files and screenshots. The folder name of the example files is the same as the name of the window executable program.
Before the program to be used, it is recommended to run the program from the input-output example data files with comparing the screenshots and the process information in process.txt. It will take about 5 working days to complete all the example exercises for PAGravf4.5 or ETideLoad4.5. Thereafter, you can use the scientific computing platform alone.
