Satellite Orbit Determination Based on Stahel–Donoho Kernel Estimator

Dynamic model error and observation model error was the main factor to badly pollute the precision of orbit determination, especially in space based observation. Model error compensation technology was researched by designing semi-parametric orbit determination regression model. Stahel-Donoho Kernel estimator was applied to solve the semi-parametric model, which can effectively estimate the model error and restrain the gross error. Simulation Experiments was processed under space based surveillance system, and results proved that the Stahel-Donoho Kernel estimator can improve the precision of orbit determination largely.
