The Design of the Height Navigation System of Target Missile

摘要

For the need of some kind of target missile, this paper proposes a method to design a height navigation system, which is composed of MOTOROLA MPX2100 pressure sensor, MCU and XW-IMU5200 inertial navigation chip. Based on the analysis of the inertial navigation system error, atmospheric pressure height model and atmospheric data, a hardware system has been designed according to the flight height range of the target missile and the algorithm of the navigation system has been improved. The result shows that the new navigation system has high precision and reliability property.
