Optical Head(OH). The OH is typically located outside the spacecraft and performs the critical functions of generating and pointing the transmit laser beam and acquiring and tracking the received beacon and receive laser beams. Major elements of the OH are :-Coarse pointing assembly used for steering the terminal line of sight.-Optical subsystem comprising telescope, optical bench and beacon collimator.-Fine pointing assembly(FPA) : This is a mechanism used in conjunction with the tracking sensor to provide the tracking function for the terminal.-Point ahead assembly(PAA) : This is similar to the FPA and is used to introduce the required point ahead offset to the transmit beam.-Acquisition sensor(AS) : This is a wide field of view sensor used during acquisition for the identification and location of the partner terminal.-Tracking sensor(TS) : This is a fast sensor that operates in a closed loop with the FPA.  2, fiche 6, Anglais, - point%2Dahead%20assembly

The satellite's integral propulsion system uses monomethyl hydrazine and nitrogen tetroxide bipropellant carried in four spherical titanium tanks. A single 490-newton(110-pound force) thruster is used for perigee augmentation and apogee burns, and thirteen 22-newton(5-pound force) thrusters are used for attitude control and stationkeeping maneuvers. Highly accurate antenna pointing control is provided by independent beacon tracking on each of the Ku-band reflector systems. The attitude control system uses an innovative combination of double-gimballed momentum wheels and magnetic field torquing, which minimizes the need for thruster use during normal on-station operations.  3, fiche 7, Anglais, - double%2Dgimballed%20momentum%20wheel

Two new tracking functions, BeaconTrac and OBS-Trac, expand tracking capabilities of the new Bendix RDR-1400 digital colour weather radar, according to the company.(...) BeaconTrac generates an inbound course to a discrete beacon. This course line is generated from the beacon display and can be rotated 360 degrees around the beacon with the HSI(Horizontal Situation Indicator) course selector. BeaconTrac will operate up to 80 nmi(about 150 km). Using the HSI course selector to position the BeaconTrac line, the pilot can readily determine an intercept or approach path. Once on BeaconTrac and heading inbound, the RDR-1400 displays left/right deviation to the beacon.  1, fiche 9, Anglais, - intercept%20path

Dans le premier de ces modes [Beacon-Trac] qui est utilisable sur des distances allant jusqu'à 80 milles marins (150 km environ), l'image sur l'écran est complétée par une ligne représentant la route à suivre pour arriver à la verticale d'une balise radar, ligne qu'il est possible de faire tourner autour de la position de la station au moyen du sélecteur de route de l'indicateur de situation horizontale. Après avoir orienté cet axe de façon appropriée, le pilote peut facilement déterminer une trajectoire d'interception ou d'approche; il lui suffit alors de mettre le cap sur la station et de corriger éventuellement celui-ci en suivant les indications d'écart gauche/droite sur l'écran.  1, fiche 9, Français, - trajectoire%20d%27interception
