| Abstract: | The accuracy of different kernels are compared with each other by using the gravity data along the offshore of American sea in DNSC08 GRA model. As the results show, in our test region, the modified Stokes kernels can improve the accuracy by 3.4 cm compared with the spherical Stokes kernel, while the difference between different modified kernels is tiny. When verifying the results with GPS/leveling data, it demonstrates the existence of a 1.17 m systematic variation between the geoid fitting before and after. Besides, all the computing accuracy can improved by 7 cm after fitting. |
| Keywords: | Stokes kernel modified Stokes kernel geoid determination gravity data GPS/leveling data |
