Chinese researchers are developing a satellite-based monitoring system capable of tracking and reporting the location of airliners in flight in nearly real time. Currently, air traffic controllers mainly rely on ground surveillance radar to track flights, but this approach is subject to many restrictions such as the radars' detection range and the absence of such equipment on the sea. In contrast, Sky Mirror will consist of a number of satellites placed in low-Earth orbit and will receive signals emitted by the ADS-B from airborne airliners, no matter where they are, and then transfer the location to ground control. Sky Mirror's first satellite will soon be launched on a Long March 11 carrier rocket to perform a two-year technological demonstration.
