| titleOfInvention | A method and system for downward continuation of aviation gravity vector based on gradient method |
| abstract | The invention discloses a downward extension method and system of an aviation gravity vector based on a gradient method. The method includes: using a high-precision ultra-high-order earth gravitational field model to calculate the correction number of the three-component gravity vector in the radial direction; obtaining an extension height; Calculate the correction number to obtain the correction value of the three components of the gravity vector in the radial direction; obtain the measurement data of the aviation gravity vector; correct the measurement data of the aviation gravity vector according to the correction value of the radial direction of the gravity vector, and obtain the extension The three-component data of the gravity vector on the surface; and the accuracy of the three-component data of the gravity vector on the extension surface is evaluated to obtain the accuracy evaluation result. The invention can realize the effective extension of the three-component measurement data of the aviation gravity vector at any point in the air, and the extension result has high precision. |
