The automation theory of intertial navigation platform for TT&C-Ship was analyzed, and the gyro scale factor error expressions were deduced based on accumulative gyro drifts. At the same time, a new gyro scale factor error modification method under the dynamic condition was introduced. The trial result indicates that the technique has high reliability, it can resolve the INS gyro scale factor error modification under the dynamic condition and data acquired meets navigation of high efficiency, therefore, it has some actual application value.
