Three-Axis Stabilization
Three-axis stabilization is a technique used in spacecraft engineering to maintain a stable orientation of a spacecraft in three-dimensional space. It involves the use of three orthogonal reaction wheels that are controlled by an onboard computer to adjust the spacecraft's attitude. The reaction wheels spin at different speeds to generate torque, which is used to counteract any external forces acting on the spacecraft, such as gravity-gradient, atmospheric drag, or solar radiation pressure. Three-axis stabilization is essential for many spacecraft missions, including Earth observation, remote sensing, and deep space exploration, as it enables precise pointing and maneuvering of the spacecraft's instruments and antennas. It also helps to minimize the fuel consumption and extend the lifetime of the spacecraft by reducing the need for frequent attitude corrections.
