Inertial Labs enhances INS solutions

May 2024 | No Comment

Inertial Labs has announced an under-development valuable addition of our INS-aiding data ecosystem to the FT743-D-SM wind/air speed sensor from FT Technologies. This Acoustic Resonance, air speed sensor, enables multi-rotor UAVs to estimate their horizontal air speed better, enhancing position estimation accuracy in GNSS-denied environments.

Inertial Labs’ team tested the feasibility of GNSS-denied navigation using an FT Technologies air speed sensor compared to a free inertial/dead reckoning solution. The FT743-D-SM air speed sensor adopts a digital anemometer-based solution by being able to estimate air speed incoming from any direction using an innovative Acoustic Resonance-based technology, which is immune to vibration and external acoustic noise. The air speed magnitude and direction allow the INS to estimate horizontal air speed in the longitudinal and lateral axis.  In all instances, the GNSS-denied position drift of the INS receiving aiding data from the dual axis air speed sensor is significantly less than that of a dead reckoning alternative.
