摘 要: 为实现北斗(BeiDou, BD)卫星导航信号的接收,设计了一种基于ARM+FPGA架构的导航接收机系统,分别介绍了接收机的硬件系统架构和软件系统架构:接收机的射频(radio frequency,RF)前端采用SE4120芯片,基带处理部分采用ARM9内核的AT91SAM9G20芯片和Cyclone Ⅲ系列的EP3C120F484芯片。同时阐述了接收机的软件设计,包括捕获引擎、跟踪引擎、解凋电文,定位解算等。该接收机可以实现对BD信号的接收与解调。
关 键 词: 飞行器控制、导航技术;北斗;ARM+FPGA;接收机

Abstract: To implement the receiring of BeiDou (BD) satellite navigation signal, a navigation receiver system is designed based on ARM+FPGA. The SE4120 chip is used as the receiver’s radio frequency (RF) front-end. The AT91SAM9G20 chip based on ARM9 core and the Cyclone III series EP3C120F484 chip are used as the base-band processing part. And the receiver’s software design is explained, including the capture engine, tracking engine, demodulation messages, and position resolution. The proposed receiver can demodulate the BD signal.
Key words: aircraft control, navigation technology; BeiDou; ARM+FPGA; receiver
