主滤波器 meaning in Chinese

senior filter

State and observation equations of each subsystem are established . filter algorithms of each subsystem and federated filter algorithms , centralized filter algorithms are also analyzed . when the sampling periods of the main filter and the subfilters are supposed to be different , the attitude determination effect is investigated and the computer simulation is done
