The Captronic Systems Aeronautical Telemetry Channel Emulator (ATCE) is designed for aviation, defense, and space applications.

It acts like a Hardware in Simulation System (HILS), simulating flight profile and propagation effects and acting as a virtual channel, so that various parameters of the telemetry system can be adjusted to optimal levels for achieving desired performance and finding any faults that are present.

The ATCE can accept data from the PCM encoder or self-generate a PCM stream as per IRIG-106 standards or accept pass-band signal at 70 MHz IF stage and generate RF signal in S-band (C-band and Ka-band also possible) as per the modulation scheme and link parameters and incorporate channel effects between aeronautical transmitter and receiver and produce a resultant RF signal for feeding to subsequent processing by real-world telemetry receiving subsystems.
