Abstract

Satellite orbit prediction is a significant research problem in visualizing low-orbit giant constellation networks. However, due to the limited resources of the onboard network equipment, the existing satellite orbit prediction methods are challenging to balance the accuracy and rapidity of the prediction. These traditional forecasting methods tend to construct perturbation models and obtain accurate orbital dynamics equations for calculation. Due to the complicated establishment of the perturbation model and the tedious calculation process, the prediction accuracy of the low-order analytical solution is relatively low, and the calculation efficiency of the high-order analytical solution is not high, which is not suitable for the orbit prediction of large-scale long-period low earth orbit (LEO) satellites. This paper proposes an orbit prediction algorithm for LEO satellites based on near-polar circular orbits. By simplifying the satellite motion model and using the least squares method to fit the data errors, we finally obtain the position information of the LEO satellite constellation network. Experimental results show that the method can perform orbit forecasting of large-scale LEO satellite constellation networks while ensuring accuracy and rapidity compared with satellite tool kit (STK) software.
