基于LEON3开源软核的卫星导航接收机设计
Design of a Satellite Navigation Receiver Based on LEON3 Open Source Soft Core
摘要
Abstract
In order to improve the performance and realize miniaturization of satellite navigation receiver, this paper introduces the design of a satellite navigation receiver with independent intellectual property and based on the LEON3 open source soft core on the DE2-115 Field Programmable Gate Array( FPGA) plat-form. The baseband System on a Chip( SoC) design of satellite navigation receiver mainly includes the ar-chitecture of LEON3 open source soft core and the homegrown IP core of acquisition modules designs based on the combination of Partial Matched Filter( PMF) and Fast Fourier Transform( FFT) and tracking mod-ules designs based on delay-locked code loop and Costas carrier loop. Finally,the performance of the re-ceiver system is verified and tested after the software design of the receiver system is completed. The experi-mental result show that the performance of the designed receiver can meet the demands. The result of acqui-sition and tracking is correct and the positioning result with an accuracy of three meters circular error prob-ability( CEP) is correct. The designed receiver with complete hardware and software source code and excel-lent performance has important implications for the development of domestic navigation.关键词
