ETEP

What ETEP does

ETEP is a France-based manufacturer of rugged airborne data acquisition and recording systems, founded in 1979 and headquartered in Cuers (near Toulon). The company designs, develops, and manufactures in-house the D.T.MUX product family — modular hardware that captures avionics, video, audio, and telemetry data on military and civil aircraft, helicopters, UAVs, missiles, and space platforms operating in harsh environments. Core technology centers on the patented Xchange® modular architecture, which allows hot-swappable acquisition modules to be stacked (up to 16 modules in the NanoX system) and supports protocols including MIL-STD-1553, ARINC 429/717/573, AFDX ARINC 664, CAN Bus, and PCM, with recording speeds up to 1 Gbps and storage up to 2 TB. The Sentinel product line provides crash-protected FDR/CVR/AIR/DLR recorders qualified to ED-112A and ED-155 standards, with crash-survivable memory units and 90-day underwater locator beacons.

The portfolio spans four lines: Telemetry & Data Acquisition (NanoX, NanoS2, COD-R, TX-MOD, Ground Station), Crash Protected Systems (Sentinel ED-112, Sentinel ED-155, CSMU), Multi-role/Mission Recorders (Nano, M, DVR), and Rugged Hardware/Accessories (NetSwitch, NanoSwitch, VSplit, remote controls, Ultra HD camera). The company sells to aerospace and defense primes, government procurement agencies, and space agencies — with 37+ named customers including Airbus, Lockheed Martin, Thales, L3Harris, Saab, Leonardo, Dassault Aviation, Hensoldt, Safran, MBDA, Naval Group, Kratos, Aselsan, Roketsan, the U.S. Army, Royal Canadian Air Force, Swedish Air Force, DGA, ESA, JAXA, CNES, DLR, ArianeGroup, and emerging eVTOL/space customers such as Lilium and The Exploration Company.

ETEP's business model is B2B enterprise sales of bespoke, quote-based hardware systems (no public pricing disclosed), supplemented by custom engineering services. The company is privately held and economically independent, with no parent company or disclosed venture funding. It holds AS/EN 9100 v2018 and ISO 9001 v2015 certifications, a NATO NCAGE code (F9281), and operates direct sales offices in France, the U.S. (Texas), and Germany, with regional channel partners in Japan, India, Turkey, and Italy.
