Directionality
Directionality refers to the ability of a spacecraft or a satellite to control its orientation and trajectory in space. It is a critical aspect of space and astronautical engineering as it enables the spacecraft to achieve its mission objectives by pointing its instruments and antennas in the right direction, maintaining a stable attitude, and adjusting its trajectory as needed. Directionality is achieved through the use of various systems such as reaction wheels, thrusters, and gyroscopes, which work together to provide the necessary torque and momentum to the spacecraft. The ability to control directionality is particularly important for scientific missions that require precise pointing and imaging, as well as for communication and navigation satellites that need to maintain a constant line of sight with the ground.
