Thales has been a key leader in inertial navigation solutions for over 50 years. By manufacturing its own unique 3-axis ring laser gyro, Thales is the only European supplier of inertial reference systems in the civil air transport market. This robust solution optimises traffic management and reduces fuel consumption, achieving worldwide RNP-AR 0.1 compliance. Our systems deliver reliability you can count on, with the highest levels of certification (DO178 & DO254 DAL-A).

STRENGTHS

  1. High accuracy demonstrated below 0.2 NM per hour

    This performance positions Thales HPIRS as the most accurate navigation system in the world.

  2. Spoofing resilience

    Thanks to advanced algorithms combining inertial and satellite data to detect and mitigate spoofing events.

  3. Very high reliability

    The Thales HPIRS has a mean time between failures (MTBF) of up to 100,000 flight hours on board civil aircraft.
