Abstract

La présente invention concerne un capteur de champ stabilisé qui recueille des données de champ, notamment des données de champ magnétique, avec un bruit de déplacement réduit. L'appareil comprend : un logement en forme de goutte d'eau, une structure d'arrimage dans le logement, une pluralité d'amortisseurs isolant les vibrations et répartis autour de la structure, un ensemble base monté sur les amortisseurs, un socle de support dont une extrémité inférieure est fixée à l'ensemble base et une extrémité supérieure libre, un palier à air sphérique unique raccordé à l'extrémité supérieure libre du socle, une plate-forme d'instrument dotée d'une goulotte inférieure creuse dont un sommet supérieur interne est soutenu sur le palier à air pour le support d'un point, des stabilisateurs gyroscopiques principal et secondaire afin de maintenir la stabilité lors du pivotement et de la rotation et au moins un capteur de champ monté sur la plate-forme d'instruments afin de recueillir les données de champ tout en étant stabilisé face au bruit de déplacement dont les vibrations, le pivotement et la rotation depuis l'ensemble base, la structure d'arrimage et le logement.
