Abstract:Considering the unique superiority of airborne gravity survey, the application of gyrostabilized platform in airborne gravity survey system was researched. Firstly,the stable loop system of singleaxis gyro stabilized platform was established by using simulation module of matlabsimulink. Secondly, the mathematical module of correction circuit was established. Under the condition that we input limited parameters, simulation results were obtained.Thirdly, the horizontal error correction model for airborne gravity measurement was established and the horizontal error correction values were obtained.
