PREDICTIVE TELEMETRY MODELS FOR AEROSPACE FLIGHT MISSIONS

Abstract

Designing an efficient telemetry system is one of the most challenging tasks in the aerospace industry due to the limited telemetry bandwidth and the restricted radio frequency spectrum allocation. In a traditional telemetry system design, a large percentage of the allotted bandwidth is consumed by the overhead information to follow various standards and protocols which results in inefficiency of output data. A dynamic simulation model is created by using the Matlab/Simulink to analyze the telemetry system performance, and it is also used to predict the overall downlink data, including sensor instrumentation, flight critical information, video, and the Consultative Committee for Space Data System (CCSDS) overhead over the mission event timeline.
