    摘要: A system for compensating the disturbance torques applied to a satellite, which eliminates the requirement for a thruster control loop. The disturbance torque itself is used as the compensating torque in order to super-impose to the incidental misalignment of the solar panel arrays an artificial misalignment that can cause the momentum vector to be adjusted to the desired direction in order to restore the correct attitude of the satellite. The direction of the momentum vector is controlled in orbit only by solar sailing, that is by organizing at prescribed times suitable manoeuvres of one of the solar panels in order to adjust the solar panel array configuration when the roll angle of the satellite exceeds a determined threshold value.

    摘要: An improved optical observation system for a movable body in space which comprises a scanning mirror, imaging optics and a sensor formed by at least one array of photodetectors arranged along a plurality of rows parallel to the apparent displacement of the image points. The electric signals from the photodetectors are driven to be transferred from one photodetector to the following along each row with a velocity equal to the velocity of the apparent displacement of the image points. An advantageous embodiment for the sensor is also disclosed together with suitable means for multiplexing the output signals developed at the ends of the rows onto a unique output line.

    摘要: The present invention relates to a novel system for folding and stabilizing flexible and continuous solar panels including fold lines. The folding system comprises a V-shaped element having arms whose free ends are fixed on both sides of the corresponding fold line of the panel, while the tip of the V is connected to the fold line itself by means of a pull sheet. The arms of the V-shaped element have a camber when the panel is unfolded, so as to exert a pulling force on the fold line, said folding systems being optionally associated with suitable stabilizing systems. The invention is useful in the folding and stabilizing of solar panels.

    摘要: A synchronized electric modulator for the control in synchronized conductance control mode of a regulation unit, thereby to assure a close control of the current peak value. A current reference is generated which varies as a function of a command signal representing the deviation of a parameter value in a system from its reference value. The current through the load is monitored and sensed to be compared to the current reference so as to produce a control signal for the regulation unit, which is dependent on the variation of the sensed current under the synchronization of external clock pulses.

    摘要: A current sensing regulator operates in a switching mode of regulation between two sensed current levels in a free-running operation, or between one of the current levels and an intermediate level in a fixed-frequency synchronization operation. The sensed current levels at which switching occurs are set through a command signal, and a comparator controls switching at the set current levels or at the occurrence of synchronization pulses.

    摘要: A magnetic suspension device comprising an annular stator surrounded by a coaxial annular rotor with an annular gap therebetween. The rotor comprises an axial ring-like permanent magnet for creating the suspension magnetic field. The stator comprises a ring-like U-shaped section of a magnetic material with an axial ring portion and a pair of parallel radial annular portions, the axial ring portion including segmental coils for producing positioning control magnetic fluxes for radial positioning of the rotor relative to the stator. The mode of construction of the stator considerably facilitates the fabrication and assembly of the device and provides a more efficient operation than the known devices.

    摘要: A low dissipation shunt or series regulator apparatus is described comprising dump switching means coupled in parallel to each power source, which dump switching means is arranged for being responsive to a control signal produced by comparator means arranged for comparing the level of the error signal with a respective reference level. Each power source has its output connected to the reference level input of the corresponding comparator through feedback circuit means in order to set two operation thresholds for the comparator, thereby allowing each dump switching means to switch cyclically between two states, a first state serving to short the corresponding power source and a second state serving to allow the power source to provide current to the load.

    摘要: A nutation damper apparatus capable of damping small nutation angles in a satellite. A permanent magnet mounted on the free end of a pendulum arm oscillates back and forth parallel to an adjacent conductive plate in the form of a circular segment having a cross-sectional area that increases from the center to its lateral ends, and induces in the plate a magnetic flux which is proportional to the deviation angle of the pendulum from its rest position.
