Embodiment Construction
[0038] Troposphere: The layer closest to the earth's surface in the atmosphere, which concentrates about 75% of the mass of the atmosphere and more than 90% of the mass of water vapor.
[0039] Tropospheric tomography: Inversion calculation is performed based on the tropospheric delay information obtained by ray scanning, and the image of the water vapor density distribution within the measured troposphere is reconstructed.
[0040] GNSS: Global positioning and navigation system, including China's Beidou, Europe's Galileo, Russia's GLONASS and the United States' GPS four major systems.
[0041] The invention solves the ill-posed problem of improving the tomographic model by integrating the water vapor product of the meteorological satellite in the tomographic modeling of the troposphere. In the process of establishing the tropospheric tomography model, the existing technology generally discretizes the tomographic area through regular grid blocks, and assumes that the water vap...
