摘要: 结合中国地域和空中交通流量分布的特点,提出了中国民航全球卫星定位系统GPS(Global Positioning System)地基区域完好性监视系统GRIMS(Ground-based Regional Integrity Monitoring System)的概念.一个包含7个监测站的地面监测网监测视界内的GPS卫星,判断其可用状况,并将判断结果和重要的监测数据发送到主控站.主控站计算中国范围内的接收机自主完好性监测RAIM(Receiver Autonomous Integrity Monitoring)空洞,同时推算全国民航飞机的实时位置,并向所有位于RAIM空洞中的飞机及时发送完好性告警信息.从卫星出现故障到飞机收到告警信息之间的告警延迟小于7s.该系统已经应用于中国民航,在保证飞行安全的同时提高了飞行效率.

Abstract: A GPS(global positioning system) GRIMS(ground-based regional integrity monitoring system) was established by considering the particularities of Chinese terrain and the distribution of air traffic flow. A ground-based monitoring network composed of 7 monitoring stations gathered data of all GPS satellites in view and made primitive judgments of GPS satellites′ health from all the data gathered. The judgments and important original data were then sent to master station. All RAIM(receiver autonomous integrity monitoring) holes in Chinese airspace, as well as positions of all airplanes of Chinese airlines, were calculated in master station. All airplanes that were considered to be in any RAIM hole would receive a notification message. The time limitation of the whole process from gathering monitoring data to the notification be received was 7s. GRIMS is used in China civil aviation and improvs both safety and efficiency.
