Telemetry, tracking, and control subsystem has been typically applied to acquire data from a remote measurand, and the information is used to control the remote target precisely. According to the purpose of telemetering and telemetry applications, the composition of telemetry subsystem varies. In addition, the telemetry data frame architecture and processing schemes are different in accordance with the characteristics of remote signal sources. Telemetry data formats and the data processing schemes are investigated in this research, and the data processing program is implemented. The developed graphical user interfaced telemetry data processing program is applied to process the surface-to-air guided missile flight test data, and it shows easy way of acquiring information and analyzing data from a remote fast-moving target.
