About this product
Product information from the supplier.
The CG-DJ-MT-1000nT Magnetometer is a high-precision aerospace-grade instrument engineered for the rigorous demands of spacecraft and satellite systems. Designed to measure the intensity and direction of magnetic fields, it serves as a critical component for attitude determination and navigation, allowing satellites to reference the Earth's magnetic field or other celestial bodies to maintain precise orientation in Low Earth Orbit (LEO) and deep space missions.
By integrating advanced sensing technologies—including fluxgate, optically pumped, or Hall effect sensors—this magnetometer detects minute magnetic variations with exceptional accuracy. When synchronized with star trackers and sun sensors, it provides a robust feedback loop for orientation control, ensuring mission stability and high-pointing accuracy for complex aerospace applications.
