摘要
针对导航信号监测问题,采用高速采集与回放系统实时采集信号,为导航信号的监测与分析提供准确的数据来源。提出了一种基于VPX架构的高速导航信号采集回放系统,详细介绍了采集回放系统硬件组成与软件实现过程,搭建测试环境进行测试,验证了系统功能性、完备性和可靠性。经测试验证基于高速总线的采集回放系统适用性好,为导航信号监测和分析提供了可靠的测试方法和手段。
Aiming at the problem of navigation signal monitoring,a high-speed acquisition and playback system is used to collect signal in real time,which can provide accurate data sources for monitoring and analysis of navigation signals.A high-speed navigation signal acquisition and playback system based on VPX architecture is proposed in this paper.The hardware composition and software implementation process of the system are introduced in detail.The test environment is built to test the system,which verifies the functionality,completeness and reliability of the system.The test results show that the acquisition and playback system based on high-speed bus has good applicability and provides reliable test methods and means for navigation signal monitoring and analysis.
