Effect of an in-flight vertical accelerometer calibration on landing accuracy after baro-inertial system failure

open access: yesAviation, 2020
An issue of improving flight safety during landing with an inertial navigation system (INS) and a failed barometric altimeter is considered. In this paper, we propose a specific algorithm for in-flight calibration of the vertical channel of INS ...

Detecting Wheel Slip to Suppress Self-Excited Oscillations in Braking Mode

open access: yesWorld Electric Vehicle Journal
The wheels of decelerating vehicles in braking mode roll with increased slip, up to complete lock-up, which is a negative phenomenon. This is effectively managed by the anti-lock braking system (ABS).
