Managing Positioning Integrity

Thales has established a new reference system to comply with the most demanding RNP-AR navigation procedures.

In 2008, Thales launched the development of a new generation of inertial reference systems for civilian aircraft, TopFlight ADIRU (air data inertial reference unit). Thales embedded in the product its know-how relative to complex hybridization algorithms, its expertise in design and manufacturing of inertial sensors (gyrometers and accelerometers), and its ability to design and develop whole navigation systems.

TopFlight ADIRU is characterized by its RNP (required navigation performance) 0.075 100% worldwide availability and, therefore, contributes to significant increases of operational aircraft capabilities up to RNP 0.1 (kerosene consumption saving, optimal traffic management, and capability to access specific airports with low decision heights).
