RADARSAT-1 est un satellite en orbite basse terrestre, à environ 800 km au-dessus de la surface de la Terre. Le plan de l'orbite est aligné de façon à être perpendiculaire au soleil, comme on peut le voir dans le diagramme de gauche. Cette trajectoire orbitale est synchronisée afin de toujours faire face au soleil et de conserver cette orientation tout au long de l'année.  4, fiche 1, Français, - trajectoire%20orbitale

R bar approach of the space shuttle towards the satellite ... along the radius vector.  3, fiche 2, Anglais, - R%2Dbar%20approach

Record number: 2, Textual support number: 1 OBS

For visualization purposes, the station's direction of motion is called the velocity vector, or V-bar for short. By convention, points in front of the station are said to be on the positive V-bar while points behind are considered negative. The imaginary line connecting the station with the center of the Earth is called the radius vector, or R-bar. Points directly below the station along this line are considered positive while points above are considered negative. Endeavour, then, will approach the station along the plus R-bar. The station will be oriented with its long axis aligned with the velocity vector, with the Unity module in "front" and Zvezda behind. Unity's nadir and zenith ports will be oriented as their names imply. This orientation, or attitude, is known as "XVV, "i. e., the station's X axis is aligned with the velocity vector. The terminal rendezvous sequence will begin with a rocket firing(TI) as Endeavour trails the station by about eight nautical miles. Once the shuttle reaches the plus R-bar, commander Brent Jett will guide the ship up from directly below. As he nears the station, he will yaw the shuttle 180 degrees so its tail is pointing in the direction of motion and its nose toward the minus V-bar. Assuming a good linkup, the shuttle will begin controlling the station's orientation for the duration of Endeavour's mission, moving the lab back into an "X-POP" attitude with the station's X axis perpendicular to the plane of its orbit. In this orientation, the long axis of the station is broadside to the velocity vector.  4, fiche 2, Anglais, - R%2Dbar%20approach

Positioned directly in front of the station's long axis, Bloomfield will manually guide Atlantis in so the docking system in the shuttle's cargo bay can mate with its counterpart on the pressurized mating adapter, or PMA. "We call it a V-bar approach, "Bloomfield said, referring to the station's velocity vector. "We’ll fly below the international space station and then we’ll fly all the way around out into the front, into what we call the V-bar, but we’re flying now out in front of the station. And then finally, we’ll fly in on that V-bar until we dock. "  2, fiche 4, Anglais, - V%2Dbar%20approach

V-bar : Flight Director Indicator... The V-bar command indicator is a pair of yellow, wedge-shaped V-bars that move up or down to command a climb or descent, and roll left or right to command a bank. The flight director system commands the V-bars to capture and track the selected heading or radio signals; or to maintain a desired pitch angle, glidepath, or an optimum speed during SC(speed command) operation. To satisfy the commands, the aircraft is maneuvered so that the airplane symbol is flown into the V-bars until the two are aligned. Input signals to the V-bars depend upon the mode of operation. The V-bars are biased from view by the instrument failure warning system; when loss of signal occurs, or sensing circuits fail that are associated with the selected mode of operation. They are also out of view when the mode selector control is in the OFF position.  3, fiche 5, Anglais, - tendency%20bar
