Abstract:

Doppler velocity can be used to perform the inflight alignment of inertial guidance systems. Reference velocity errors, both noise and bias, cause initial guidance system velocity errors and intial platform tilt errors, which in turn cause position errors. The values of these initial errors must be found to determine their effect on the position errors. The position error propagation equation was developed and the position error and CEP of the missile due to reference velocity errors were found. Also, the dependence of the position error on the halfpower frequency o the reference velocity noise was investigated. Author
