  • Attitude control device for a satellite and method for controlling the attitude of a satellite
    Patent number: 11535404
    Abstract: An attitude control apparatus for a satellite includes: at least three electric motors, wherein the at least three electric motors are arranged in such a way that a torque may be generated with any orientation of an associated torque vector, and a controller, wherein the controller is configured to drive the at least three electric motors based on a torque controller. The torque controller is adapted to operate the at least three electric motors outside a rest state only when an acceleration torque and a braking torque are required to execute an agile attitude change maneuver. There is also described an associated method.
    Type: Grant

  • Method for recognising hot targets on the Earth
    Patent number: 7480572
    Abstract: A method for detecting a hot target on the Earth by a satellite is disclosed. The satellite includes a sensor for acquiring data in spectral channels in the IR spectrum, and a navigation system for detecting position and orientation data of the satellite. The method includes the steps of subjecting the acquired data to a system correction by radiometric and geometric calibration files stored on the satellite; detecting a hot target on board from the system-corrected data by multi-channel thresholding; geo-referencing the hot target by the position and orientation data of the satellite and the geometric calibration files; temporarily storing the geo-referenced hot target on the satellite; and transmitting the temporarily stored hot target by a transmitting unit to a receiving unit on the Earth.
