PRACTICAL CONSIDERATIONS IN CIVIL AIRCRAFT FLIGHT TEST MISSIONS IMPLEMENTING TMOIP TECHNIQUES USING SATELLITE COMMUNICATION LINKSDu, Xianyu; Zhou, Yi; Yi, Xiaoqian; Instrumentation Department, COMAC Flight Test Center (International Foundation for Telemetering, 2018-11)In order to cover the complete flight path of a large civil aircraft during its flight test missions, Telemetry-over-IP (TMoIP) systems have become a standard technique solution in COMAC Flight Test Center. In this paper, practical considerations in implementing the TMoIP systems using a satellite communication link will be discussed, along with the applicable satellite modem parameters. Based on the Command & Control Center located besides the Shanghai Pudong International Airport, several typical cities represent different directions and climatic conditions across the mainland of the country are analysed. Thanks to the high mobility and rapidly deployable satellite communication vehicle, and the rental of satellite time can be specified in contract at a reasonable price and scheduling can be coordinated a short time in advance, high-risk flight test subjects can be monitored and instructed at the head-quarter where more specialist can participate and better ground test and verification equipments can be arranged to support the missions.
