When the roll gimbal hits its stop, it precesses pitch into the other pitch stop. This process could continue throughout the first phase of rapid align. To prevent this, a rate signal is developed from the roll VG [vertical gyro] pick-off signal and fed to platform pitch gimbal servo loop. 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. 2, record 2, English, - pitch%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 2, French, - boucle%20de%20tangage

In a three-axis four-gimbal inertial platform, there is a small misalignment angle, [delta], between the pitch and inner roll gimbals. The problem... is to drive this angle equal to zero. This involves designing a control loop for nulling [delta]. By properly designing the control system, an orthogonality loop can maintain the angle [delta] near zero for reasonable values of pitch angle. 1, record 3, English, - three%2Daxis%20four%2Dgimbal%20inertial%20platform

Roll Alignment. In the second phase of rapid alignment, the platform roll gimbal is controlled by the gyro roll pick-off and is damped by the roll tachometer. To position the VG [vertical gyro] roll gimbal quickly, the roll component of the liquid level, an indication of platform roll gimbal vertical error, is fed into the pitch loop. The large roll error signal drives the platform pitch gimbal torque motor causing the spring stop to press against the gyro pitch gimbal. 1, record 6, English, - roll%20alignment
