Control Moment Gyroscope (CMG) technology increases efficiency of satellite operations
The use of NEWTON increases the operational efficiency of Earth Observation, and makes agile satellite missions possible. Satellites equipped with NEWTON are able to significantly reduce the re-visit time and increase the number of image scenes acquired on an area. For agile satellites within a given area, shorter acceleration and braking phases allow the line of sight to be quickly retargeted. Steering rules and control electronics are included as part of the NEWTON package from Airbus Defence and Space.
While similar CMG technology has been previously applied, the Airbus Defence and Space approach significantly reduces equipment cost, allowing an agile satellite to become more affordable. One key difference was to “not reinvent the wheel”, but to reuse an existing space qualified reaction wheel within the NEWTON mechanical actuator design. Additionally, a building block approach was deployed so that major assemblies are interchangeable between NEWTON packages expediting development cycles and reducing parts count.
With this approach Airbus Defence and Space has now available a NEWTON family of products designed for a wide range of satellite platforms, from 500kg to even more than 2000kg. The mechanical actuators of these packages are all derived from the flight proven 15-45 CMG successfully used on the Pléiades and SPOT Earth Observation missions.
