Abstract:

Inertial guidance instrumental error separation is the key to verify the space-ground consistency of inertial guidance systems and the accuracy identification test of missile weapons, which provides important support for the accuracy assessment and subsequent improvement of missile weapons. Although the problem of instrumental error separation of platform inertial guidance systems used in traditional ballistic missiles has been fully studied, with the development of new inertial guidance devices and the development requirements for hypersonic vehicles and other new equipments, new challenges have been posed for inertial guidance instrumental error separation. This paper analyzes the development status and characteristics of inertial guidance instrumental error separation from three aspects: launch conditions, required elements and inertial guidance mode. Besides, it analyzes and prospects the development trend under new requirements.

Key words: guidance instrumental error separation, inertial navigation, space-ground consistency, accuracy assessment, system identification
