摘要
随着卫星导航系统的不断发展和完善,星载卫星导航接收机的研制己经成为卫星导航领域重要研究方向之一。设计了一种基于ZYNQ-7000的星载卫星导航接收机,具有GPS/BDS双模兼容、高精度和高动态等特点。详细介绍该星载接收机总体设计架构、捕获跟踪设计、定位测速算法及电离层误差修正,最后通过模拟源模拟低轨卫星场景,验证了设计方案的可行性。同时,通过统计星载接收机定位误差,证明了该星载接收机满足指标要求。
With the continuous development and perfection of the satellite navigation system, the development of space-borne satellite receiver becomes an important research direction of satellite navigation system. A satellite-borne satellite navigation receiver based on ZYNQ-7000 is designed, which has the characteristics of GPS/BDS dual-mode compatibility, high precision and high dynamic. The overall design frame, capture and tracking design, positioning velocity-measurement algorithm and ionospheric error correction are described in detail. Finally, simulation on low earth-orbit satellite indicates the feasibility of the proposed scheme. Meanwhile, the statistics on the positioning error of the satellite-borne receiver indicate that the on-board receiver could meet the requirements of design indicators.
