Guidance
Guidance refers to the process of directing a spacecraft or missile along a desired trajectory. It involves the use of various systems and techniques to ensure that the vehicle stays on course and reaches its intended destination. Guidance systems can be based on a variety of principles, including inertial navigation, celestial navigation, and GPS. Inertial guidance systems use accelerometers and gyroscopes to measure the vehicle's motion and calculate its position and velocity. Celestial guidance systems use stars or other celestial objects to determine the vehicle's position. GPS guidance systems use signals from a network of satellites to determine the vehicle's position and velocity. Guidance systems are critical for the success of space missions, as even small errors in trajectory can result in significant deviations from the intended path.
