ADVANCES IN A LOW-COST SOFTWARE-DEFINED TELEMETRY SYSTEMDon, Michael; Ilg, Mark; U.S. Army Research Laboratory (International Foundation for Telemetering, 2017-10)The United States Army Research Laboratory (ARL) has developed a Pulse Code Modulated (PCM)/Binary Frequency Shift Key (BFSK) telemetry system using a low-cost commercial Software Deﬁned Radio (SDR). Where as traditional radio systems are implemented in hardware,much of the functionality of SDR is deﬁned in software. This gives them the ﬂexibility to accommodate military telemetry standards as well as other specialized functions. After a summary of previous development, new telemetry advances are described, focusing on telemetry transmitter, Advanced Encryption Standard (AES) encryption, and layered protocol design. Many of these functions were proven in a ﬁeld experiment at Yuma Proving Ground, AZ in March of 2017 where data was successfully encrypted, transmitted, decoded, and processed in real-time.
