Air Data Unit 2.0
The NEW Air Data Unit 2.0 (ADU2) provides high-fidelity pitot airspeed, barometric altitude, and external temperature data for air platforms, enabling precision navigation and reliable positional data.
AVAILABLE TO ORDER FROM 29TH MAY, 2026.
Air Data Unit 1.0 is no longer available. If you are an existing ADU 1.0 customer and require product information, please refer to the downloads section below.
When integrated with an Advanced Navigation Inertial Navigation System (INS), such as a Certus Evo, the ADU2 provides resilient aerial navigation in GNSS-denied and contested environments. ADU2 provides accurate data to constrain INS drift.
This extends the duration, range, and accuracy of the INS’s position and heading, establishing a new standard for scalable, high-throughput sensor integration and enabling highly accurate dead reckoning for UAV platforms.
The ADU2 is available in three variants, engineered to support air platforms operating across broad speed envelopes.
Features
Accurate Air Data Sensing
Absolute and differential pressure sensors, with external temperature sensor.
Thermal Stability
Factory calibrated to ensure accuracy over a wide temperature range.
Navigation Resilience
Improves inertial navigation position and heading accuracy when GNSS is compromised.
Rugged Design
Designed for reliable operations in harsh environments. With low size, weight and power, for uncrewed platforms.
Specifications
Operational
Performance is based on pairing with an Advanced Navigation Certus Evo INS.
*Exceeding the Differential Proof Pressure can permanently damage the unit.
