| Fiber optic gyro inertial navigation system based on fiber optic gyroscope asangular motion measuring instrument of a strapdown inertial system. In tacticalmissiles, air defense weapon system, unmanned aircraft has wide military andcivilian applications. In this paper, research on optical fiber gyro inertialnavigation system design, it is in view of the optical fiber gyro inertialnavigation system miniaturization, low cost, modular and carry out thedevelopment trend of engineering and technology research, the purpose is toprovide a smaller weapons systems, lower prices, installation is more simpleinertial navigation system.This paper first briefly introduces the optical fiber gyro inertial navigationsystem and the basic knowledge and basic working principle of fiber optic gyro,as to provide theoretical basis for system design. Then analyzed the optical fibergyro inertial navigation system requirements, system miniaturization,modularization design idea is put forward. Paper mainly completed the systemhardware and software design. Overall thought under the guidance of thehardware design mainly adopts DSP+DSP double CPU structure system,centered on VC33gyro inertial measurement module is mainly responsible fordata, add table, temperature, and GPS data acquisition, C6713as the core ofinertial navigation computer module is mainly responsible for the navigation datadecoding, error compensation and other operations. Both coordination, give fullplay to their respective special skill. Double DSP software is designed forwriting applications, including inertia measuring combination and inertialnavigation computer firmware program and guidance, all programs usingmodular programming, and the general modules such as data acquisition, errorcompensation, the navigation calculating encapsulated in the form of interfacefunctions, such as secondary developers provide users do, achieve the goal of theopen software platform technology research.Finally, complete the performance test of fiber optic gyro inertial navigationsystem experiment, the shock, vibration, high and low temperature environment, navigation experiment, inertial navigation system hardware and software reliablework, realize the whole function of optical fiber gyro inertial navigation system,and has good performance, which laid a foundation for the engineeringapplication. |
