Design of the Flight Controller Software Update System of Missiles With GJB 1188A Interface Under Whole Missile State

With the rapid development of missile weaponry in the new era, intelligent software update has become an important direction for future development of missile weaponry system. In order to update the flight controller software of the airborne missile under the whole missile state, this paper designed a flight controller software update system of missiles with GJB 1188A interface under the whole missile state. The host computer of this system first transmits the compiled target files to the missile flight controller through 1553B bus of GJB 1188A interface. Then the flight controller independently writes the received file into the program storage based on IAP (In Application Programming). Finally, the host computer verifies the software update. This system has high reliability, strong flexibility in field experiments, electric missile joint-tests and other application scenarios, solving the problem of flight controller software update of missiles with GJB 1188A interface under the whole missile state.
