Magnetometer

The Magnetometer is a sophisticated instrument designed to measure the strength and direction of magnetic fields, primarily used in spacecraft and satellite systems for attitude determination and navigation. It detects the local magnetic field generated by the Earth or other celestial bodies, providing critical data for the spacecraft’s orientation control. The magnetometer typically consists of sensitive magnetic sensors such as fluxgate, optically pumped, or Hall effect sensors, which are capable of detecting minute variations in the magnetic field. This data is then processed to calculate the spacecraft's attitude relative to the magnetic field, providing feedback for orientation adjustments. Magnetometers are often used in combination with other attitude control systems like star trackers or sun sensors to improve accuracy and ensure stability in navigation. They are an essential part of satellite systems, helping maintain precise pointing and attitude control in low Earth orbit (LEO) and deep space missions, where magnetic fields are a reliable reference.
