Title (EN) IN-FLIGHT AZIMUTH DETERMINATION
(FR) DÉTERMINATION D’AZIMUT EN VOL
Abstract:
(EN) The presently disclosed subject matter includes a method and system directed for calculating azimuth of an airborne platform during flight based on IMU measurements, without using GNSS data, gyrocompassing or magnetometers operating on the ground for determining the azimuth.
(FR) La présente invention concerne un procédé et un système destinés à calculer l’azimut d’une plateforme aéroportée pendant le vol sur la base de mesures d’UMI, sans utiliser de données GNSS, d’alignement de la centrale ou de magnétomètres fonctionnant au sol pour la détermination de l’azimut.
