Best Source Selection (BSS) has become a major topic at many modern telemetry ranges and ground stations around the world today. Best Source Selection techniques for telemetry applications, have been around for well over 25 years in one form or another. With the introduction of Next Generation Correlating Best Source Selection techniques a decade ago, the BSS function has evolved into an extremely powerful tool for the real-time and post flight recovery of telemetry data. These Next Generation techniques, currently operational at a variety of ranges around the world today, provide significant performance increases at these sites. As ranges continued to evolve, moving toward more network centric solutions, Correlating Best Source Selectors have also followed this trend while still dealing with the issues of encrypted data, latency and switching from stream-to-stream without dropping lock on downstream frame synchronizers. This paper describes the evolution of Best Source Selection as well as the advantages and disadvantages of a variety of different approaches and BSS modes of operation that are available today.
