Abstract:With the development of aeronautical flight test telemetry technology, the requirement for flight test telemetry becomes higher and higher. The integration flight test and multifighter coordination flight test are urgent requirements for aeronautical flight test. At the same time, with the promotion of rapid development of wireless communication, telemetry transmission in aviation flight test develops gradually from the traditional "oneway, pointtopoint remote sensing" mode to "2way, multipoint to multipoint integration of space telemetry and remote network" mode. In the new mode, bidirectional wirelessbased telemetry network faces the challenges of complex channels, i.e. multipath transmission, Doppler frequency shift and the timevarying link quality. Given this, the progress and current status of telemetry technology in aeronautical flight test is introduced, and its technical challenges are discussed. We review the current research status and works. Finally, the trends, major research challenges and concerns are analyzed, which should be focused on wireless telemetry transmission in networking flight test telemetry.
