用于飞机追踪的北斗地面数据监测与评估系统设计与实现

Design and Implementation of Beidou Data Monitoring and Evaluation System for Aircraft Tracking

民用航空飞行器在全球区域范围内的全过程飞行追踪和监测一直是航空飞行器研发工作的重点。由于我国在西藏新疆等边远地区缺乏ADS-B以及ACARS信号覆盖,无法保证飞机的实时跟踪,采用北斗RDSS短报文可以作为填补民机跟踪监控的技术空白。基于北斗短报文数据链路,可以实现对运输类飞机的跟踪与定位,并对飞机飞行情况进行实时监测。针对飞行空中通信环境的复杂性,为了提高通信成功率,在对空中信号质量的分析基础上,优化了抗干扰天线设计并提高了信号接收质量,实现了包括飞机轨迹追踪显示、飞机数据告警以及基于北斗的数据分析等功能。经过实际应用测试验证,平均数据接收成功率提高了3.53%,系统设计的功能和性能指标均达到设计目标,能够有效补充现有飞机监控信号空白。

The full process flight tracking and monitoring of civil aviation aircraft in global regional has always been a focus of aviation aircraft research and development work.Due to lack of ADS-B and ACARS signal coverage in remote area,such as Tibet and Xinjiang,the civil aircraft can not be tracked in time.The Beidou communication technique based on RDSS short message can fill the gap in civil aircraft monitoring.Based on the Beidou short message data link,tracking and positioning of transportation aircraft can be achieved,and real-time monitoring of aircraft flight conditions can be carried out.In order to improve the communication successful rate in the complex air channel environment,the anti-jamming antenna design is optimized and the signal reception quality is improved based on the analysis of the air signal quality.Functions including aircraft trajectory tracking display,aircraft data alarm and data analysis based on Beidou are implemented.According to the verification result in trial environment,the average data reception success rate has increased by 3.53%,the function and performance indicators of system design have reached the design goals,which can effectively supplement the existing aircraft monitoring signal gap.
