Study of composite guidance applicable to launch vehicles

Composite Guidance on the base of Inertial Navigation System,as it keeps the independence and anti-jamming performance of INS and has a more higher guidance precision,has been used in the most of aerospace field.Among the many models,the INS+GNSS mode and INS+CNS mode are the most adaptable to launch vehicles.This paper analyzes the Composite Guidance mode applicable to launch vehicle and studies the above mentioned mode's primary problem of engineering technology and application.
