Safran DSI - CORTEX BEST SOURCE SELECTOR Select the Best Telemetry Source in Real-Time

The CORTEX Best Source Selector (BSS) is the ultimate choice for real-time telemetry source selection. It’s the go-to tool for pinpointing the best Telemetry source among multiple antennas tracking the same airframe across various channels. 

The Best Source Selector streamlines the selection process by automatically choosing the top Telemetry stream, even from up to 16 sources or more, using a combination of signal quality metrics and other criteria. With its extensive capabilities in aligning paths and compensating for delays, the CORTEX Best Source Selector ensures optimal source selection, no matter where the antennas are located or what kind of range infrastructure you’re working with.
