The Operational Direction "Reference Systems and Planetology" contributes to the elaboration of reference systems and timescales, integrates Belgium in the international reference frames, and studies the interior, rotation, dynamics, and crustal deformation of the Earth and other terrestrial planets and moons of our solar system. We actively participate in the development of Global Navigation Satellite Systems (GNSS, such as GPS, GLONASS and Galileo) observation networks and their scientific products. The Operational Direction is responsible for the accurate realization of time in Belgium and participates in the international time scale UTC using GNSS time transfer. It is also involved in the Solar and Terrestrial Centre of Excellence (STCE) where GNSS observations are used to monitor the Earth's ionosphere and troposphere. The operational direction has a long history of research in geodesy, in particular in the astronomical and geophysical causes of rotation variations of the Earth. Additionally to the planet Earth, we have extended our research in geodesy and geophysics to the other terrestrial planets Mars, Venus, and Mercury, and to the moons of the solar system planets. The operational direction is involved in current and upcoming planetary missions and actively contributes to the development of new missions.
La Direction Oprationnelle Systmes de rfrence et Plantologie contribue l'laboration de systmes de rfrence et dchelles de temps, intgre la Belgique dans les repres de rfrence internationaux, et dans les tudes de l'intrieur de la Terre, de sa rotation, de sa dynamique et de ses dformations crustales aux niveaux local, rgional et global, ainsi que celles des autres plantes telluriques et des lunes de notre systme solaire. Nous participons activement au dveloppement des rseaux d'observations du Systme Global de Navigation par Satellites (GNSS, comme GPS, GLONASS et GALILEO) et de leurs produits scientifiques. La Direction Oprationnelle est responsable de la ralisation de lheure prcise en Belgique et participe l'chelle de temps internationale UTC utilisant le transfert de temps par GNSS. Elle est galement implique dans le Centre d'Excellence Terrestre et Solaire (STCE) o les observations GNSS sont utilises pour surveiller l'ionosphre de la Terre et la troposphre. La Direction Oprationnelle a dj quelques dcennies d'exprience en godsie et en particulier dans l'tude des causes astronomiques et gophysiques des variations de la rotation de la Terre. En plus de nos recherches en godsie et gophysique de la Terre, nous avons tendu nos recherches aux autres plantes terrestres Mars, Vnus et Mercure, et aux lunes des plantes du systme solaire. La Direction Oprationnelle est implique dans des missions plantaires actuelles et venir et contribue activement au dveloppement de nouvelles missions.
De operationele directie "Referentiesystemen en Planetologie" werkt mee aan de ontwikkeling van referentiesystemen en tijdschalen, integreert Belgi in de internationale referentiesystemen, en bestudeert de inwendige structuur, de rotatie, de dynamica en de korstvervorming van de Aarde en andere aardse planeten en manen van ons zonnestelsel. We nemen actief deel aan de ontwikkeling van waarnemingsnetwerken en wetenschappelijke producten van Global Navigation Satellite Systems GNSS, zoals GPS, GLONASS en Galileo). De operationele directie is verantwoordelijk voor de nauwkeurige realisatie van de tijd in Belgi en participeert in de internationale tijdschaal UTC met behulp van GNSS-tijdsoverdracht. Ze is ook betrokken bij het Solar and Terrestrial Centre of Excellence (STCE) waar GNSS-waarnemingen worden gebruikt om de ionosfeer en troposfeer van de Aarde te bestuderen. De operationele directie heeft een decennialange ervaring in de geodesie, in het bijzonder in de studie van de astronomische en geofysische oorzaken van rotatieveranderingen van de Aarde. Naast ons onderzoek in de geodesie en geofysica van de Aarde bestuderen we ook de andere aardse planeten Mars, Venus en Mercurius, en manen van de planeten van ons zonnestelsel. De operationele directie neemt deel aan huidige en toekomstige planetaire missies en draagt actief bij aan de ontwikkeling van nieuwe missies.
