独立式北斗机载导航天线适航要求及关键指标分析
Airworthiness requirements and key indicator analysis of independent BeiDou airborne navigation antenna
摘要
Abstract
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.关键词
