摘　　要：北斗卫星导航系统在民航领域的应用已进入“机载导航应用”阶段,与“仅用作定位追踪”阶段相比,此阶段对机载卫星导航系统的要求更为严格。然而,在独立式北斗机载导航天线方面,目前国内仅有“仅用作定位追踪”的标准(CTSO-2C604a)可供参考,无法满足“机载导航应用”阶段对天线的适航要求,同时由于目前应用广泛的GPS信号与北斗信号体制不同,其相关标准也无法完全符合独立式北斗机载导航天线要求。为此,文中针对机载导航天线的技术特点,对当前国内外相关标准进行了综合分析,并考虑了适用性、安全性、当前紧迫需求以及未来发展方向,研究了独立式北斗机载导航天线的关键指标,并提出了相应的修订方案。通过研究建立了一套机载导航天线的指标要求和标准体系,旨在为独立式北斗机载导航天线设计提供必要的工业支持。The application of BeiDou satellite navigation system in civil aviation has entered the stage of″airborne navigation application″,which imposes stricter requirements on the airborne satellite navigation system in comparison with the stage of″positioning and tracking only″.However,in the field of independent BeiDou airborne navigation antennas,there is only the standard CTSO-2C604a available for reference currently,and it is designed for″positioning and tracking only″and fails to meet the airworthiness requirements for the stage of″airborne navigation application″.Additionally,due to the different signal systems between the widely used GPS and BeiDou,the existing related standards fail to fully comply with the requirements for BeiDou airborne navigation antennas.To address this issue,this paper focuses on the technical characteristics of airborne navigation antennas.A comprehensive analysis of current domestic and international standards is conducted,considering factors such as applicability,safety,urgent needs and directions of the future development.The key indicators for independent BeiDou airborne navigation antennas are investigated and corresponding revision schemes are proposed.On the basis of the research,a set of performance requirements and standard systems for airborne navigation antennas are established,which aims to provide necessary industrial support for the design of independent BeiDou airborne navigation antennas.
