Abstract: This paper presents the effects of geomagnatics and wakes on spacecraft surface charging in low orbit.According to the charging mechanism,a numerical simulation is set up by using current collection and “inside out”method of particle tracing,the surface equilibrium potentials of the conductor and non conductor surface of spacecraft are given.The numerical calculation,results agree with the observation and the theoretical analysis.
