Due to the disadvantages in present magnetometer bias determination methods such as complex calculation, low accuracy of estimation and non real-time, a differential value method is developed for magnetometer bias estimation of micro-satellite without attitude information. This method avoids the impact of quartic nature and use the iterative method to satisfy real-time applications. Simulation results indicate that the accuracy of estimation using the differential value method can be less than 50 nT, which is more accurate compared with other methods and has no need to set an initial state. This method will reduce the demand for computing power effectively and improve the accuracy, while the magnetometer bias calibration of micro-satellite is being carried out on-orbit.
