Abstract

Since the successful launch of the GRACE gravity satellites in 2002, they have been able to monitor the Earth's gravity field with high temporal and spatial resolution. Currently, GRACE products are primarily provided in the form of spherical harmonic coefficients. Although the algorithms for calculating the Earth's gravity field model using spherical harmonic coefficients are well-established, there is a lack of program design and algorithms suitable for beginners. This design, based on MATLAB software, provides programs for calculating geoid undulation, gravity anomaly, and equivalent water height using the CSR-06 spherical harmonic coefficients.
