Better Reliability Achieved with INS/SAR/Loran-C Integrated Navigation System

We improved the performance of INS/SAR integrated navigation system by introduction of Loran - C into it. Especinlly INS/SAR/Loran - C integrated navigation system is more reliable because China can control Loran -C system independently and can also develop Loran -C system within China's natiotal boundary.INS/SAR integrated navigation system utilizes the Anage -aided function of SAR to rectify INS when onboard digital map data are available. By introdudng Loran - C into INS/SAR system, the whole system performances of fault - tolerance and dynamics can be improved. This paper presents the integration principle and method of INS/SAR/Loran -C integrated navigation system. The provided simulatlon results show the excellent performance of INS/SAR/Loran -C integrated navigation system. In addition, this system has many other functions such as scouting, arms dropping and termital guidance, since SAR can be used in seeking, tracking, aiming and so on.
