Automatic Program of Gravity tide Pre-processing

Author: Tian Guie (1980-), women, Mainly engaged in geodetic survey, tidal theory and tidal processing, etc.
In order to improve efficiency of pre-processing gravity observations, the theoretical tides are simulated on the basis of the foregone tidal parameters, and the simulating gravity observations are obtained by combining the local atmospheric gravity, the pole gravity and the length of day gravity. Based on the gravity observations, repairs the abnormal data such as jumps, steps and spikes in gravity observations. In this paper, the software FTsoft, which can automatically identify and repair data such as jumps, steps and spikes and other abnormal data, is designed and implemented on the Matlab platform, which improves the work efficiency. Comparing the results of treatment with FTsoft and Tsoft, it is found that the standard deviation of the result of Ftsoft is smaller than Tsoft, it further proved that Ftsoft is a effective method of pre-processing gravity tides.
Key words: Gravity tide / FTsoft / Automatic pre-processing / Matlab
