| Abstract: | A Federated Least Square Filtering (FLSF) method is used for multi-sensor information-fusion in INS/DS (Double Star)/GPS integrated navigation system. Four different federated filter designs are applied to FLSF and the fault-tolerance design is discussed. The simulation result indicates that the method can improve the precision and fault-tolerance for the INS/DS/GPS integrated navigation system. |
