Title (EN) "LOW COST INS"
(FR) SYSTÈME DE NAVIGATION INERTIELLE À FAIBLE COÛT
Abstract:
(EN) This disclosure relates to an underground mining vehicle comprising a three-axis MEMS gyroscope rotatable about a rotation axis and a gyroscope interface that calculates a first rotation rate bias with respect to a first axis different to the rotation axis, a second rotation rate bias with respect to a second axis different to the first axis and different to the rotation axis, a rotation rate about the rotation axis based on the Earth rotation rate vector by correcting the rotational measurement data using the first rotation rate bias and the second rotation rate bias and a third rotation rate bias with respect to the rotation axis based on the calculated rotation rate about the rotation axis. A navigation unit receives the first rotation rate bias, the second rotation rate bias and the third rotation rate bias and calculates a pose of the vehicle.
(FR) La présente invention concerne un véhicule minier souterrain comprenant un gyroscope MEMS à trois axes pouvant tourner autour d’un axe de rotation et une interface de gyroscope qui calcule un premier biais de vitesse de rotation par rapport à un premier axe, différent de l’axe de rotation, un deuxième biais de vitesse de rotation par rapport à un deuxième axe, différent du premier axe et différent de l’axe de rotation, une vitesse de rotation autour de l’axe de rotation d’après le vecteur de vitesse de rotation terrestre par correction des données de mesure de rotation à l’aide du premier biais de vitesse de rotation, du deuxième biais de vitesse de rotation et d’un troisième biais de vitesse de rotation par rapport à l’axe de rotation d’après la vitesse de rotation calculée autour de l’axe de rotation. Une unité de navigation reçoit le premier biais de vitesse de rotation, le deuxième biais de vitesse de rotation et le troisième biais de vitesse de rotation et calcule une pose du véhicule.
