A horizontal datum is a specified coordinate system for a collection of positions on the surface of the earth. Traditionally, horizontal datums have used classical surveying methods(i. e. measuring distances and angles through triangulation surveys) to best fit to the surface of the earth.  1, record 1, English, - horizontal%20datum

[Un] référentiel géodésique [est une] série de caractéristiques définissant la zone de référence ou le système des coordonnées de référence utilisés pour le contrôle géodésique lors du calcul des coordonnées de différents points au sol. Les référentiels géodésiques sont généralement définis en tant que référentiels géodésiques horizontaux et verticaux séparément.  5, record 1, French, - syst%C3%A8me%20de%20r%C3%A9f%C3%A9rence%20planim%C3%A9trique

The Local Vertical Local Horizontal coordinate system is referenced to the near-circular orbital plane. In order to specify the attitude of the Station with respect to the Local Vertical Local Horizontal, a system based on Eulerian angles of roll, pitch and yaw is used.  3, record 3, English, - local%20vertical%20local%20horizontal

The ISS [International Space Station] flies in an attitude that is referenced to the orbital plane of ISS using a set of local vertical/local-horizontal axes. The origin is at the ISS centre of mass, with the x-axis pointing along the direction of the orbital velocity vector (sometimes referred to as the "ram" direction). The z-axis points directly towards the Earth, and the y-axis parallel to the truss assembly ... This orientation is referred to as "x-axis toward the velocity vector" Torque Equilibrium Attitude and is the "normal" orientation of the ISS. The overall ISS design is optimised to fly in this attitude, which places the most laboratory modules in the "best" microgravity volume, supports attitude reboosts, service vehicle docking and minimises aerodynamic drag.  3, record 3, English, - local%20vertical%20local%20horizontal
