Analysis and judgment of key issues in data process for optical tracking and measurement

Regarding the application value of optically tracked and controlled data in unspecified arc segment, the means from random error characteristic, comparison of nominal parameters, influence of error propagation to measurement and control station distribution analysis have been presented to carry out comprehensive analysis of the measured data in an all-around way to understand the availability of optically tracked data unspecified by practical verification and application in engineering, which is used as an effective evidence for external ballistic data process and make ballistic parameter more precise and reliable as a result of redundant data.
