AI Technical Summary
Technical Problem
Existing technologies cannot effectively solve the problem of leveling marine and airborne gravity and magnetic data for multi-directional survey lines, resulting in the inability to eliminate systematic errors.
Method used
By configuring multiple measurement lines into multiple measurement line groups according to directional data, determining and correcting the first correction parameter for each measurement line group, and further determining the second correction parameter for each measurement line, multi-directional correction of gravity and magnetic data can be achieved.
Benefits of technology
Systematic errors in marine and airborne gravity and magnetic data were eliminated, enabling effective leveling of survey lines in multiple different directions.
