La cha\u00eene d\u2019approvisionnement g\u00e9od\u00e9sique s\u2019appuie sur un vaste r\u00e9seau d\u2019organisations partenaires. En effet, ni les donn\u00e9es, les infrastructures et l\u2019expertise, ni la mission de l\u2019IGN ne s\u2019arr\u00eatent aux fronti\u00e8res nationales.<\/p>\n

Une infrastructure g\u00e9od\u00e9sique fiable ne peut \u00eatre garantie qu\u2019en \u00e9troite collaboration avec des partenaires nationaux et internationaux. Ces collaborations ont un double objectif : soutenir efficacement les utilisateurs en Belgique et veiller \u00e0 ce que la g\u00e9od\u00e9sie belge s\u2019int\u00e8gre dans l\u2019infrastructure g\u00e9od\u00e9sique europ\u00e9enne et mondiale.<\/p>\n

Partenaires internationaux<\/strong><\/p>\n

\"\"<\/p>\n

L\u2019Institut g\u00e9ographique national est un partenaire agr\u00e9\u00e9 du Centre d\u2019excellence g\u00e9od\u00e9sique mondial des Nations unies (UN-GGCE), situ\u00e9 \u00e0 Bonn. Le Centre soutient la mise en \u0153uvre de la r\u00e9solution des Nations unies relative \u00e0 un rep\u00e8re de r\u00e9f\u00e9rence g\u00e9od\u00e9sique mondial pour le d\u00e9veloppement durable et encourage la coop\u00e9ration internationale dans le domaine de la cha\u00eene d\u2019approvisionnement g\u00e9od\u00e9sique mondiale<\/a>.<\/p>\n

L\u2019IGN contribue \u00e0 ce partenariat en assumant un double r\u00f4le. D\u2019une part, il assure la maintenance de l\u2019infrastructure g\u00e9od\u00e9sique belge, notamment l\u2019Active Geodetic Network et les syst\u00e8mes de r\u00e9f\u00e9rence nationaux, qui apportent une contribution concr\u00e8te \u00e0 la cha\u00eene d\u2019approvisionnement g\u00e9od\u00e9sique mondiale.<\/p>\n

D\u2019autre part, l\u2019IGN joue un r\u00f4le actif au sein du Comit\u00e9 d\u2019experts des Nations unies sur la gestion de l\u2019information g\u00e9ospatiale \u00e0 l\u2019\u00e9chelle mondiale (UN-GGIM) : il pr\u00e9side le groupe de travail europ\u00e9en \u00ab UN-GGIM: Europe \u2013 Cadres de r\u00e9f\u00e9rence g\u00e9od\u00e9siques \u00bb<\/em> et repr\u00e9sente les int\u00e9r\u00eats de la Belgique au sein du Sous-comit\u00e9 des Nations unies sur la g\u00e9od\u00e9sie.<\/p>\n

Ce partenariat traduit la conviction qu\u2019un cadre de r\u00e9f\u00e9rence g\u00e9od\u00e9sique robuste et mondial rel\u00e8ve d\u2019une responsabilit\u00e9 commune et que les instituts nationaux tels que l\u2019IGN jouent un r\u00f4le indispensable dans sa mise en place et sa pr\u00e9servation.<\/p>\n

L\u2019Observatoire royal de Belgique est charg\u00e9 de calculer le syst\u00e8me de coordonn\u00e9es europ\u00e9en ETRS89, un processus que l\u2019IGN soutient en fournissant les donn\u00e9es GNSS utilis\u00e9es dans ces calculs. Les deux partenaires se concertent \u00e9galement r\u00e9guli\u00e8rement afin d\u2019adopter une position belge commune dans un contexte g\u00e9od\u00e9sique international.<\/p>\n

\"\"<\/p>\n

L\u2019IGN collabore avec le Service g\u00e9ologique de Belgique \u00e0 la mise en place de stations de r\u00e9f\u00e9rence g\u00e9od\u00e9siques int\u00e9gr\u00e9es (IGRS). Celles-ci combinent des antennes GNSS permanentes avec des r\u00e9flecteurs qui r\u00e9fl\u00e9chissent de mani\u00e8re optimale les signaux des satellites radar. La combinaison de deux techniques de mesure ind\u00e9pendantes am\u00e9liore la pr\u00e9cision et la fiabilit\u00e9 des \u00e9tudes sur les mouvements du sol.<\/p>\n

L\u2019IGN travaille en \u00e9troite collaboration avec FLEPOS, un service des autorit\u00e9s flamandes, et avec WALCORS, un service de l\u2019administration wallonne. L\u2019objectif de cette collaboration est de garantir la plus grande pr\u00e9cision possible du signal de correction RTK, auquel font confiance des milliers d\u2019utilisateurs professionnels. L\u2019IGN d\u00e9finit les coordonn\u00e9es de r\u00e9f\u00e9rence des antennes GNSS permanentes qui constituent la base de ces signaux de correction et en assure la maintenance.<\/p>\n","protected":false},"excerpt":{"rendered":"
