Application of matrix theory in design and calibration of spacecraft ground system

The ground wire is very important for the stable and reliable of Spacecraft System. After summarizing the existing resistance analysis method of spacecraft system, the article proposes a feature matrix model used to represent the resistance properties of the ground system. The feasibility of the model has been proved from theoretical analysis and verified by experiments. This model has solved the problem of calculating the resistance value of the tributary of the spacecraft system effectively. It is valuable and convenient to design, calibration and fault diagnosis for Spacecraft Ground System.
