The MS-15 from SENSORPIA is a Magnetometer that senses attitude by measuring 3-axis components of the earth’s magnetic field. This 3-axis magnetometer has a measuring range of +/- 60 μT and a resolution of 0.01 nT at 1Hz. It has a linearity of +/- 0.1 % and a maximum axis alignment of +/- 1 degrees. The magnetometer supports RS-422 communication interface and has a bandwidth of 10 Hz. It requires an input voltage of 15 V and has a power consumption of less than 1.3 W. The magnetometer weighs 250 g and measures 35 × 112 × 35 mm. It is developed for scientific satellites and has space flight heritage.
