摘要
针对光纤陀螺受温度影响较大的特点,降低惯导系统计算机的功耗可以提高系统精度,本文对器件选型和电路设计进行详细介绍。本导航计算机选用TI公司的TMS320VC33为核心的数字信号处理器,并用FPGA实现逻辑、计数以及接口功能,实现低功耗惯导计算机的设计,并成功的应用于某型号高精度定位定向系统中。
For fiber optic gyroscope affected by temperature,Reduce the power of the computer can improve the accuracy of the system.This paper discusses the selection of the device and design of a navigation computer.The core of the navigation computer is DSP chip TMS320VC33 of TI Company;the functions of logic,count and interface circuit have been designed with FPGA.the actual computer was designed and was used in a strap-down positioning and directive system.
