Abstract
A three-axis attitude control for a low-orbiting satellite. A sensor which measures in two axes is a magnetometer, and a satellite is positioned on an inclined orbit at an inclination angle of approximately 25 degrees to approx. 90 degrees. The satellite has been provided with an overall spin by spin wheels, and actuators generate torque on all three axes of the satellite. Accordingly, this is applicable to three-axis attitude control of a low-orbiting satellite that includes a sensor which measures in two axes and that includes one or several spin wheels.
Claims1
A three axis attitude control arrangement for a low-orbiting satellite positioned on an inclined orbit at an inclination of approximately 25 degrees to approximately 90 degrees, comprising:
- a sensor corresponding to a magnetometer and for measuring in two axes;
- at least one spin wheel for providing the satellite with an overall spin hy;
- and
- a plurality of actuators for generating torque on all three axes of the satellite.
