Abstract:

Platform inertial navigation system is important equipment of modern navigation. Because of variable environments and different manufacture levels, there is a distinct discrepancy between individual platform inertial navigation. Analysis of the collected performance deterioration data as a whole cannot reflect the individual discrepancy. To address this problem, on-line reliability assessment of platform inertial navigation system is investigated. Using composite Poisson process, a deterioration model is established based on the deterioration characteristics and failure mechanism of the platform inertial navigation system. The method for parameter estimation is given. Computation analysis of samples shows that the model can describe the performance deterioration law of the platform inertial navigation system, and is thus helpful for knowing the reliability level of the platform inertial navigation system.

Key words: on-line reliability, performance deterioration, composite Poisson process, reliability assessment, platform inertial navigation system
