\n Le module de sondage haute performance offre une plage de mesure de 0,15 m \u00e0 300 m, s'adaptant \u00e0 diff\u00e9rents environnements de travail. L'ADCP ou le sonar lat\u00e9ral permettent des applications polyvalentes.<\/span><\/span><\/span><\/span>\n<\/div>\n

\n Les g\u00e9om\u00e8tres installaient les stations de base.<\/span><\/span><\/span>\n<\/div>\n
\n
\n En raison de l'immensit\u00e9 du lac, les g\u00e9om\u00e8tres ont pr\u00e9vu de diviser la zone de relev\u00e9 en plusieurs parties et de la mesurer de l'int\u00e9rieur vers l'ext\u00e9rieur. Apr\u00e8s la pose, l'iBoat BS2 a lanc\u00e9 la mission de relev\u00e9.<\/span><\/span><\/span><\/span>\n<\/div>\n
\n L'eau presque glaciale n'a pas frein\u00e9 l'iBoat BS2\u00a0; il a fonctionn\u00e9 aussi parfaitement que pr\u00e9vu. Ses excellentes performances ont \u00e9t\u00e9 rendues possibles par son puissant syst\u00e8me d'alimentation, son moteur CC sans balais et ses h\u00e9lices car\u00e9n\u00e9es amovibles.<\/span><\/span><\/span><\/span>\n<\/div>\n
\n La pr\u00e9cision de l'iBoat BS2 \u00e9tait toujours aussi \u00e9lev\u00e9e, avec une erreur de d\u00e9calage ne d\u00e9passant pas 10 cm. Les donn\u00e9es du lev\u00e9, dont les lignes \u00e9taient pratiquement parall\u00e8les, ressemblent \u00e0 un tableau int\u00e9ressant.<\/span><\/span><\/span><\/span>\n<\/div>\n
