Problems solved by technology

However, since the aviation carrying platform is moving, it is necessary to perform magnetic compensation through high-precision attitude projection to eliminate the interference introduced by the movement of the carrying platform. Eliminating these interferences not only requires the measurement accuracy of position, attitude data and full tensor magnetic data to be as accurate as possible High, and require position, attitude data and full tensor magnetic data must maintain a high degree of synchronization, but in the aeromagnetic superconducting full tensor gradient measurement and control system, due to the different data sources of full tensor magnetic data and position, attitude data , resulting in out-of-synchronization of full tensor magnetic data and position and attitude data, and low synchronization accuracy when data synchronization is performed through existing technologies
