Founded May 2026 • 100% bootstrapped

Independent R&D, striving for aviation technology sovereignty

Founded in May 2026 by passionate avionics and software engineers, CNSVN chose a 100% bootstrapped path without external venture capital, staying laser-focused on engineering excellence, technical fidelity, and academic rigor.

At operational airports, allowing trainees or new engineers to test fault scenarios on live mission-critical CNS systems operating 24/7 is strictly prohibited for flight safety. CNSVN bridges this critical gap with digital simulation, enabling hundreds of fault injections without affecting real flight operations.

  • Strict engineering precision

    Based on official ICAO, FAA, and OEM technical manuals (Mopiens, Indra, Selex, Rockwell Collins).

  • Purpose-built for training & exams

    Scenario-based training, automated calibration checks, and comprehensive fault diagnosis grading.
