| Abstract: | The solutions of boundary value problem of horizontal gravity gradient are deduced in detail, according to the property that the first and second horizontal derivatives of the spherical harmonics are also general spherical surface harmonics. The formulas for computing the gravity anomaly and the deflection of the vertical from horizontal gravity gradient are deduced according to differential relationship between disturbing potential and gravity quantities. This paper makes the application of full satellite gradiometry sensor more perfect. |
