摘要
介绍了高精度模数变换(ADC)和现场可编程门阵列(FPGA)在惯性导航系统(INS)与全球定位系统(GPS)构成的组合导航系统中的应用,讨论了运用多片ADC同时对陀螺仪、加速度计等惯性传感器信号进行并行采集,使用FPGA实现对ADC进行时序控制和对采集到的信号进行硬件数字滤波的方案,最后给出了系统测试结果,达到了预期的设计目的。
This paper introduces high- precision Analog - to - Digital Converter (ADC) and Field Programmable Gates Array (FPGA) application approach in a Inertial Navigation System(INS) and Global Positioning System(GPS) integrated navigation system. It discusses how to utilize AD2151 converter to collect data of multi gyroscope and accelerometer,how to control A/D by FPGA, how to filer the data signal in FPGA. Finally,the test result of system is presented,which meets the design goal so well.
