Abstract
As precision instrument and equipment, the Inertial Navigation System (INS) not only shall has high accuracy index, but also possess high working reliability. Commonly, there are two methods to improve reliability of the INS, one is to increase the reliability of single device and reduce the rate of occurrence of failures (ROCOF). The second is to adopt the concept of tolerance design, by adding additional hardware resources and algorithm in the system. If in case one component in the system fails, it could be tested and the fault can be reconfigured through redundant components and algorithms, and reach the purpose of absorbing or isolating fault. Restricted by manufacturing technology, there is limited space to guarantee the reliability of INS by improving the reliability of single component. Many studies show that redundant technique has apparent effects for improving reliability of system.
