Estimation of Accuracy and Comparison of Models of the Earth, the Moon and Mars Gravitational Potential

Transactions of IAA RAS, issue 38, 50–54 (2016)

Keywords: gravity potential model, Earth, Moon, Mars, comparison, accuracy estimation.

Abstract

The estimation of internal accuracy for selected models of the gravitational potential of the Earth, the Moon and Mars was carried out. These models can be found on the ICGEM website. The comparison of models was performed using several criteria. We have demonstrated that combined geopotential models have higher accuracy than purely satellite ones. The selenopotential model based on data of GRAIL mission has a higher quality as compared to other models. The comparison of geopotential models demonstrates high differences in high-frequency range for satellite models and in mid-frequency range for combined models. Models of the Moon and Mars have significant differences in mid- and high-frequency range.

AB  - The estimation of internal accuracy for selected models of the
gravitational potential of the Earth, the Moon and Mars was carried
out. These models can be found on the ICGEM website. The comparison
of models was performed using several criteria. We have demonstrated
that combined geopotential models have higher accuracy than purely
satellite ones. The selenopotential model based on data of GRAIL
mission has a higher quality as compared to other models. The
comparison of geopotential models demonstrates high differences in
high-frequency range for satellite models and in mid-frequency range
for combined models. Models of the Moon and Mars have significant
differences in mid- and high-frequency range.
