A compact airborne flight termination receiver.
Programmable Flight Termination Receiver is a compact airborne flight termination receiver and tone decoder for flight termination system applications that utilized tone based command messaging. FTR provides highly sensitive superheterodyne RF receiver whose center frequency is programmable.
The versatile tone decoder can be programmed to decode 3 or 4 tone sequences / frequencies among 20 IRIG tones and provides command outputs for flight termination devices.
FTR can be enabled for full fail-safe operation, including programmable loss of tone duration. FTR is designed using latest technology and modern production processes to provide a reliable and rugged product.
