Firstly, based on the dynamic measurement error mechanism of gravity gradient, the key technology for dynamic measurement is combed. Secondly, the typical Y-12 fixed-wing aircraft used in domestic aerial remote sensing operation is taken as an example to analyze the typical gravity gradient measuring dynamic conditions. Finally, the ground simulation test based on the dynamic parameters of the carrier is carried out. The technical requirements of the demonstration are achieved, laying the foundation for the gravity gradient measurement in real dynamic conditions.
