System life prediction algorithm design and data analysis of inertial navigation

Equipment has long service period and high reliability requirements, equipment support personnel not only need to complete the necessary test and repair, but also have to make clear the future development trend of equipment performance and the life expectancy during life cycle. Life prognostic can help them to improve the equipment maintenance and ensure high logistics and readiness capability of equipments. In this paper, the author researches and analyses the life prediction algorithm, pre-treatment method and optimization method of equipment service. These algorithms are applied and validated by calculating and analysis the practical test data, which can provide theories basis and references for the weapon PHM.
