A correction model for Angle drift in target area is established through ray-tracing target area light path of ICF (Inertial Confinement Fusion) driver.

As the ship or fleet size is defined, the channel width is dependent on the track zone width, and track zone width is dependent on the drift Angle of navigation.

It is firstly put forward that the Angle vibration of platform under vibration situation is the main factor causing gyro drift and acceleration bias.
