Abstract

In order to overcome the flaw of incoherent localization of common vehicle-mounted guided systems,the characteristics of Nios Ⅱ soft nuclear processor nimble in disposition and strong in expansibility are utilized to design a SoPC-based dual-positioning system with GPS and GSM modules.The μC/OS-Ⅱ operating system and Nios Ⅱ processor,memory and interface assembly are embedded quickly into FPGA by means of SoPC Builder development kit.The functions of man-machine interaction module,control module and connection module are implemented by the aid of individual chip.The general GPS navigation aid can realize the high-accurate real-time continual localization.This design is easy to upgrade and expand hardware′s foundation without changing the hardware.
