La plate-forme inertielle de l'IU [Instrument Unit, cœur du lanceur de fusée] fournit une référence fixe qui permet au lanceur de s'orienter dans l'espace. En clair, une plate-forme inertielle, c'est un appareil qui reste toujours orienté de la même façon quoiqu'on fasse, un peu comme l'eau dans un verre. L'environnement qui entoure la plate-forme se déplace, mais cette dernière reste toujours dans la même position.

Système de navigation à inertie [...] Le système se compose d'une plate-forme inertielle, d'accéléromètres intérieurs et d'un ordinateur. La plate-forme, qui capte le déplacement de l'aéronef au-dessus du sol, comporte deux gyroscopes. Ceux-ci maintiennent leur orientation dans l'espace pendant que les accéléromètres captent toutes les variations de cap et de vitesse de déplacement. L'information provenant des accéléromètres et des gyroscopes est transmise à l'ordinateur, qui corrige la trajectoire afin de tenir compte des facteurs comme la rotation de la terre, la dérive de l'aéronef, la vitesse et la vitesse angulaire de virage.

Inertial platform ... Stable platforms utilizing gyroscopes references have been successfully used for several decades as attitude and heading reference systems (AHRS), fire control baselines for aircraft, ships, missiles, and for inertial navigators.

For a three-gimbal platform... the inner gimbal or controlled member is the stable platform on which the three gyros and accelerometers are mounted. As the vehicle to which the system is attached moves, the gyros sense any rotation and drive the gimbals in the opposite direction to null the gyro rate. As a result, the inner platform remains fixed in inertial space. 5, record 2, English, - controlled%20member

On distingue deux types de systèmes inertiels : - Les systèmes sur cardans, dont la plate-forme contenant les accéléromètres est montée sur les cardans internes de trois gyroscopes. La plate-forme est isolée de toute rotation du véhicule et son attitude reste constante pendant le mouvement du système. Ces dispositifs complexes sont précis, mais complexes et onéreux. - Les systèmes dits «strap-down», qui utilisent des accéléromètres et des gyroscopes soumis aux mouvements du véhicule.

The gyros are used to maintain the platform's inertial orientation by sensing rotations of the platform caused by vehicle-rotation-induced friction at the gimbal pivot points... One gyro-called the vertical gyro-is oriented so its input axes are aligned with the X and Y platform axes; its input axes provide IMU [Inertial Measurement Unit] platform roll and pitch stabilization. The second gyro is oriented so that one input axis lies along the platform's Z axis and the other lies in the X-Y plane. This gyro-the azimuth gyro-provides platform yaw stabilization with the Z input axis, while the second input axis is used as a platform rate detector for built-in test equipment. 3, record 5, English, - azimuth%20gyroscope

The sensors for angular velocity are vibrating gyroscopes (3 axes, to detect rotation and pitch/roll pendulations of the payload). An error signal is obtained differencing the signal from the azimuth gyroscope and a constant level settable from the telemetry, which controls the speed of rotation. Such error signal drives an analog PID [Proportional Integral Differential] circuit; the output of the PID is connected to the PWM [Pulse Width Modulation] driver supplying current to the pivot azimuth motors. 3, record 5, English, - azimuth%20gyroscope

When the pitch gimbal goes into its stop and roll starts to precess, the roll pick-off signal is fed into the pitch loop to drive the pitch gimbal out of its stop. 1, record 8, English, - platform%20pitch%20gimbal%20servo%20loop

Lorsque le cardan de roulis heurte sa butée, il applique la précession de tangage à l'autre butée de tangage. Ce phénomène pourrait se reproduire pendant toute la première phase de l'alignement rapide; pour empêcher cela, un signal proportionnel est émis à partir du signal détecteur de roulis du VG [gyroscope de verticale] et envoyé à la boucle d'asservissement du cardan de tangage de la plate-forme. Lorsque le cardan de tangage heurte sa butée et que le cardan de roulis commence sa précession, le signal détecteur de roulis est envoyé à la boucle de tangage pour éloigner le cardan de tangage de sa butée. 1, record 8, French, - boucle%20d%27asservissement%20du%20cardan%20de%20tangage%20de%20la%20plate%2Dforme

The transfer mode should only be used after rapid alignment sequences have been completed in order to reduce the possibilities of initial drift associated with a cold start.... With the transfer gyro properly aligned, calibrated and connected to the plaftorm harness, the transfer command switch on the transfer handle is held depressed for 15 seconds, actuating relays [x, y, z]. The transfer gyro error signal is passed to the azimuth gimbal torque motor which aligns the spin axis of the platform DG [directional gyro] to that of the transfer gyro heading, derived by placing the transfer gyro on the prealigned mount, to the fore and aft line of the A/C [aircraft]. 1, record 27, English, - transfer%20gyro%20heading

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 35, English, - roll%20component

L'important signal d'erreur de roulis commande le moteur couple du cardan de tangage de la plate-forme et fait que la butée à ressort presse contre le cardan de tangage. 1, record 37, French, - alignement%20de%20roulis

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 38, English, - pitch%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. 3, record 38, English, - pitch%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 38, French, - composante%20en%20tangage
