Design and Development of Low Cost Flight Termination System Encoder Based on DDS AD9850 for Flight Vehicle

FTS (flight termination system) is a system that used to terminate a mission on the air vehicle such as;
rocket, aircraft, and UAV (unmanned air vehicle). FTS is basic safety on the rocket launch for anticipation mission
fail. FTS consists 2 systems; encoder system (in transmitter system) and decoder system (in the receiver system).
This research just focused on the FTS encoder with generates the sine waveform as signal tone. The method transmitted FTS signal by using radio transceiver HT (handy-talky) with frequency VHF and the audio frequency as the FTS signal tone. The encoder system can generate the audio frequency from 20 Hz till 20 KHz as sine waveform by use DDS method. The experiment results shown that the DDS AD9850 can generate the sine waveform from 0 Hz till 40 MHz depend on the frequency given
