Inertial Labs has integrated the FT Technologies FT743-D-SM Acoustic Resonance air speed sensor into its inertial navigation systems (INS) to improve the accuracy of horizontal air speed estimation for multi-rotor UAVs.

The sensor, which is immune to vibration and external acoustic noise, allows the INS to estimate horizontal air speed in the longitudinal and lateral axes.

The system can be used in various military, defense, and civilian applications, including wind energy, marine navigation, UAVs, and dynamic positioning systems.
