Telemetry recording is the backbone of every successful flight test program. Without it, engineers are operating blind — generating enormous volumes of sensor data from an aircraft or missile and then losing the information before it can be analyzed. Whether validating a new propulsion system, characterizing flight envelope boundaries, or confirming weapons integration, telemetry recording captures every critical parameter in real-time and preserves it for post-flight review.
At its core, telemetry recording captures data streams transmitted from an airborne test article and stores them in a structured, retrievable format. These streams carry hundreds or thousands of parameters — temperatures, pressures, accelerations, control surface positions, engine health indicators — encoded as Pulse Code Modulation (PCM) or in IP-based formats specified by IRIG 106 Chapter 10 and Chapter 11. The recorder must operate with near-zero latency, handle enormous throughput, maintain time accuracy to microsecond precision, and remain immune to vibration, thermal cycling, and electromagnetic interference endemic to aerospace environments.
A single missed data point during a critical flight event can invalidate an entire test card, requiring an expensive re-flight. Worse, corrupted or incomplete data can lead to incorrect engineering conclusions, potentially allowing an unsafe condition to go undetected. High-fidelity telemetry recording enables engineers to reconstruct every moment of a flight with complete confidence, supports rapid post-flight data mining, and enables long-term trend analysis across multiple sorties.
IRIG 106 Chapter 10 defines the standard format for recording telemetry data, including PCM, analog, MIL-STD-1553, video, and Ethernet streams into a single time-correlated file. Chapter 10 files are universally readable by analysis tools across the range community, ensuring that data recorded today can still be processed decades from now. Parraid's IMUX G2e and G2eH recorders have the ability to record two Chapter 10 files simultaneously – local and/or remote, simultaneous playback and on-the-fly channel adjustment.
As flight test instrumentation increasingly adopts Ethernet-based data buses and networked FTI architectures, IP-based recording has become essential. IRIG 106 Chapter 11 extends the standard to cover UDP/TCP-based telemetry streams, enabling recorders to capture data arriving over standard network interfaces without analog conditioning. The IMUX RE-CON network recorder addresses this evolution directly — it provides automatic format detection for known telemetry formats, binary file recording, playback to any network endpoint, and conversion to IRIG 106 Ch 10 files on-the-fly.
Selecting a telemetry recorder requires careful consideration of data rate requirements, channel count, recording media capacity, form factor constraints, and the specific mix of data bus types in your test article. Airborne recorders face additional SWaP challenges, while ground-based recorders prioritize capacity and throughput. Programs running multiple simultaneous test articles need recorders capable of handling multiple independent streams without cross-contamination.
With over 30 years of experience supporting defense and aerospace programs, Parraid has developed a complete family of telemetry recording solutions. From the IMUX G2e for straightforward Chapter 10 applications to the network-intelligent IMUX RE-CON for modern IP-based ranges, the portfolio spans the full spectrum of flight test recording requirements.
