The in-orbit magnetic property of Taiji-1 is crucial for enhancing the satellite's attitude-control performance and the acceleration noise model of the gravitational reference sensor. By using the global optimization method, the remnant magnetic moment of Taiji-1 is estimated to be (-1.42 -0.19 -0.06) Am-2.
Taiji-1's in-orbit magnetic property is significant for the improvement of the satellite's attitude-control performance and the acceleration noise model of gravitational reference sensor. Test data of satellite drifts have been used to construct the model including interaction among the magnetic field; remnant magnetic moment and induced magnetic moment so as to estimate the satellite's magnetic property. Using the global optimization method, the remnant magnetic moment of Taiji-1 is estimated to be (-1.42 -0.19 -0.06) Am-2.
