Advanced Navigation Releases Air Data Unit

Advanced Navigation has announced the release of their air data unit. The air data unit measures pitot airspeed and barometric altitude pressure on fixed wing aircraft. It can be used standalone for air data or connected to one of Advanced Navigation's Spatial series of GPS/INS products for significantly enhanced dead reckoning performance in fixed wing aircraft.

The Air Data Unit features very high accuracy absolute and differential pressure sensors. These are factory calibrated over a wide temperature range to further increase measurement accuracy and provide the best air data possible through varying conditions. On top of factory temperature calibration, every time the air data unit powers up, it performs a self excitation calibration to adjust for small deviations of bias and scaling error. This allows the system to compensate for calibration ageing and means that it never needs to be returned to the factory for recalibration.

The system outputs air data at 20 Hz over an RS232 serial interface and is housed in a miniature rugged environmentally sealed enclosure.
