A fire control system with SVF method

Afire control system with space virtual feedback (SVF) is presented. The whole tracking systems is close-looped by the space virtual feedback line which is the line of sight (LOS). But the parts in the system, such as tracking subsystem and servo subsystem, run in the state of open-loop. Because the SVF tracking method is used in the system, the corrector can be removed in this system architecture. So the tracking performances of the whole system are improved well.
