Airborne gateway: key technology of earth observation system in the space-air-ground integration network

Abstract

Abstract In traditional system of remote-sensing emergency services in space-air-ground integration network, the existing units of earth observation system operate independently from each other, the rate of data transmission and process can not meet the requirements, which makes the efficient actions taken after at least ten hours of the emergency. This has become a bottleneck for effectively responding to emergency events. The airborne gateway is the key technology to break through this bottleneck. The result of the rate test shows that our airborne gateway rate has reached 937M/s. Besides, it can also effectively detect moving target after preprocess. With the gateway, the three independent units are connected to a network, which works well and improves the efficiency of data processing and shorten the response time.
