By comparing the differences between various drift models and adjustment methods through simulated gravity data adjustment, certain optimizations were made to the gravity adjustment algorithm. Methods for multiple segment difference adjustment and constrained linear programming adjustment were proposed. The results indicate that the multiple segment adjustment method outperforms other adjustment methods in some aspects, while the constrained linear programming adjustment method demonstrates overall superiority over other adjustment methods.
