Satellites orbit determination based on particle filtering
粒子滤波在卫星轨道确定中的应用

The great information error of initial estimation and non-Gaussian distribution of state and measurement error may exist in the satellite orbit determination problem.To solve these two problems,the sampling-importance-resampling(SIR) particale filter is used to estimate the satellite orbit.The filter measurement information is obtained from the magnetometer's measurement.To avoid the sampling sparse problem of this filter method,a rough method has been used.Finally a simulation is given to estimate the satellite orbit.
