The MS-37 from SENSORPIA is a Magnetometer that measures  3-axis magnetic field components with small weight and low power consumption. This 3-axis magnetometer has a measuring range of  ± 60 µT and a resolution of 150 nT. It has a linearity of ± 0.2 % and a maximum axis alignment of ± 1 degrees. The magnetometer supports an analog output communication interface and has a bandwidth of 10 Hz. It requires an input voltage of 5 V and has a power consumption of less than 0.2 W. The magnetometer weighs 50 g and measures 30 × 60 × 18.5 mm. It is designed for attitude control for satellites by measuring environmental magnetic field and changes of magnetic fields due to the magnetic objects.
