Attitude Sensor. The TSS POS/MV(Position and Orientation Systems for Marine Vessels) is an inertial navigation system delivering full 6 degree-of-freedom position and orientation systems for ships. It combines data from an inertial unit made up of three acceleration meters and three gyrolasers(fibre optic gyroscopes) and two GPS antennas. It delivers the following data with a sampling frequency of 1-200 Hz : roll and pitch(accurate to 0. 02°) ;heave(accurate to 5% amplitude) ;true heading(accurate to 0. 1°).  1, record 1, English, - attitude%20sensor

Des gyroscopes mécaniques à suspension dynamique, très utilisés dans les centrales à cardans, peuvent également être montés sur une centrale à composants liés, de performances plus modestes, comme une centrale d'attitude. Il s'agit d'instruments électromécaniques à masse tournante entraînée en rotation par un moteur électrique au travers d'un joint flexible qui laisse au rotor toute liberté angulaire dans les directions perpendiculaires à l'axe de rotation.  5, record 1, French, - centrale%20d%27attitude

Centrales d'attitude. La centrale TSS POS/MV (Position and Orientation Systems for Marine Vessels) désigne un système de navigation inertielle qui procure des solutions d'orientation et de positionnement à six degrés de liberté pour les navires. Elle combine les informations provenant d'une centrale inertielle constituée de trois accéléromètres et trois gyrolasers (gyroscopes à fibres optiques) et de deux antennes GPS. Elle délivre avec une fréquence d'échantillonnage 1-200 Hz les informations suivantes : roulis et tangage (précision 0.02°); pilonnement (précision 5 % de l'amplitude); cap (précision 0.1°).  6, record 1, French, - centrale%20d%27attitude

Three Axis Magnetometer [-] TAM... Redundant TAMs are provided to sense the local strength and direction of the Earth's magnetic field. Each TAM consists of a sensor and a separately packaged electronics unit. The analog outputs provided by the TAM allow for sensing magnetic field data in three orthogonal axes. TAM-Operation Once the TAM is powered there will be no ground interactions necessary. The TAM data is used by the FSW ACS [Flight Software Attitude Control Subsystem routine to determine the local magnetic field when reaction wheel momentum unloading is deemed necessary via the magnetic torque rods [Landsat].  3, record 2, English, - three%20axis%20magnetometer

The basic attitude sensor was the three-gyro inertial reference package. It contained two air-tight integrating gyro units to sense pitch and yaw, and one miniature integrating gyro unit to sense roll. The pitch and roll gyros were torqued by signals obtained by two Barnes mod IIA infrared horizon sensors. Gyrocompassing oriented the vehicle to an orbit plane yaw reference by detecting a component of the programmed pitch rate through the roll horizon sensor. The geocentric pitch rate(typically 4 deg/min, for a low-altitude orbit) was programmed as a constant torque to the pitch gyro. This pitch component, if a yaw error was present, would be sensed differentially when compared with the roll components of the two horizon-sensor heads. The differential would be seen as a function of yaw error.  2, record 4, English, - roll%20component

During heading align, the rotor of the resolver is positioned so that it transforms the N-S and E-W liquid level signals into pitch and roll components which are referenced to heading. The pitch component is amplified, demodulated and summed with amplified and demodulated feedback signals from the VG [vertical gyro] roll and pitch pickoffs and the pitch synchro. The combined signal is then modulated, amplified and converted to DC [direct current] to drive the platform pitch gimbal torque motor until the input signals are nulled.  1, record 4, English, - roll%20component

Durant l'alignement sur le cap, le rotor du résolver est mis en position de telle sorte qu'il transforme les signaux des niveaux à liquide N.-S. et E.-O. en composantes de tangage et de roulis en référence au cap. La composante de tangage est amplifiée, démodulée et composée avec des signaux de réaction amplifiés et démodulés venant des capteurs de roulis et de tangage du VG [gyroscope directionnel] et du synchro de tangage. Ce signal composé est alors modulé, amplifié et converti en courant continu pour entraîner le moteur couple du cardan de tangage de la plate-forme jusqu'à ce que les signaux d'entrée soient annulés.  2, record 4, French, - composante%20en%20roulis
