To orient a payload mounted on a space vehicle platform, a control signal is applied to an electric motor linking the payload and the platform to produce a pitchover torque so as to generate the necessary tilt of the payload; an estimate is made of the amount of counter torque that must be applied to the platform when the control signal is applied to the electric motor and a compensating signal is determined, to apply to the platform and through an inertial gyro system with which the platform is equipped, the compensating torque required to offset the estimated counter torque; the control signal for the electric motor and the compensation signal for the inertial gyro system are applied at the same time.
Pour commander en orientation une charge utile embarquée sur une plate-forme d'un véhicule spatial: ~ on détermine un signal de manoeuvre propre à faire appliquer à la charge utile par un moteur électrique reliant la charge utile à la plate-forme, un couple de basculement propre à générer le basculement nécessaire, ~ on prédit le couple de réaction devant être appliqué à la plate-forme lorsque ce signal de manoeuvre sera appliqué au moteur électrique, et on détermine un signal de compensation propre à faire appliquer à la plate-forme, par un système de gyroscopes d'inertie dont elle est munie, un couple de compensation opposé à ce couple de réaction prédit, et ~ on applique simultanément le signal de manoeuvre au moteur électrique et le signal de compensation au système de gyroscopes d'inertie.
