Aeronautical Telemetry Channel Emulator

While designing, developing, or validating a ground telemetry system which communicates with any flight vehicle like, missile, aircraft, or satellite. it is important to test and fine tune its performance before putting it in real world application. This can be achieved with Captronics Aeronautic Telemetry Channel Emulator. Its state-of-the-art architecture along with AGI-STK user interface makes it a unique product in field of RF Simulation and Testing, not made by any Indian company before.


What is an Aeronautic Telemetry Channel Emulator?

It is extremely important to prepare, fine tune and validate ground telemetry systems, objectively for a given flight profile and link parameters, so that once it is put in real world application, it can deliver the desired performance. The flight vehicles are typically missiles, aircraft, and satellites. The ATCE acts like a Hardware in Simulation System (HILS), simulating flight profile and propagation effects acting as a virtual channel, so that various parameters of telemetry system can be adjusted to optimal levels for achieving desired performance and finding any faults that are present.

About Captronics Aeronautic Telemetry Channel Emulator (ATCE):

The Captronics ATCE can accept data from 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.

Key Features of  ATCE


User has flexibility to create channels into various modes like,1 Tx Antenna – 5 Ground Stations, 5 Tx Antennas – 1 Ground Station, Duplex (Max 5 each), Multiple Tx on single platform and 1 Ground Station.



Multiple options for propagation effects available like, Line of sight, Finite-aperture loss due to distance, Rocket plume effects, Plasma effects and many more.
