摘    要:星基增强系统作为广域增强手段,能为民用航空提供花费较低、可用性更高的导航功能。研制开发具备 SBAS 功能,满足民航使用要求的机载设备符合 GNSS 发展趋势。分析梳理了北斗星基增强系统(BDSBAS)的机载处理算法,从准确性、完好性等民航进近着陆的应用性能出发,对研制的北斗机载多模接收机于 2021 年 5 月在天津机场开展的 SBAS 飞行验证数据进行了分析评估。结果显示研制的机载设备在当前 BDSBAS 信号条件下可以满足 APV-I 进近的定位精度要求,试验期间未见完好性异常。

关 键 词:机载设备  北斗星基增强系统  精密进近  飞行试验

Abstract:As a wide-area enhancement method, the satellite-based augmentation system can provide civil aviation with lower-cost and higher-availability navigation functions. The research and development of airborne equipment with SBAS function, which meets the requirements of civil aviation, conforms to the development trend of GNSS. The airborne processing algorithm of the BDSBAS is analyzed and sorted out in the paper, flight test data of developed airborne equipment with SBAS function from the perspective of accuracy and integrity is analyzed and evaluated, which flight test carried out in Tianjin airport in May 2021. The results show that the developed airborne equipment can meet the accuracy requirements of the APV-I approach under the current BDSBAS signal, and there was no integrity abnormality during the test.
