2023年4月花土沟高高原机场MMR无人机飞行测试数据

2023年4月，在青海省海西州花土沟高高原机场（高高原机场），针对研制设备“多模式多基增强机载北斗导航设备（MMR）”搭载国产无人机开展高高原机场飞行测试。通过开展不同飞行科目的测试，验证MMR满足任务书指标ABAS、GBAS、SBAS等的多模式多基增强功能，适应高海拔高寒气候环境，支持GNSS多星座多多频点，达到LNAV、LPV-200、GAST-C的定位精度指标要求。

In April 2023, a flight test was carried out at the Huatugou High-Altitude Airport in Haixi Prefecture, Qinghai Province (a high-altitude airport). The test utilized a domestic unmanned aerial vehicle (UAV) carrying the domestically developed "Multi-Mode Multi-Base Enhanced Airborne Beidou Navigation Equipment (MMR)". Through tests covering various flight procedures, the validation confirmed that MMR satisfies the multi-mode and multi-base enhancement functions specified in the mission document for standards including ABAS, GBAS and SBAS, can adapt to high-altitude and frigid climatic environments, supports multiple constellations and multi-frequency points of GNSS, and meets the positioning accuracy requirements for LNAV, LPV-200 and GAST-C.
