MOURA - Magnetometer

The tri-axial vector field magnetometer is developed by INTA, Spain. It consists of a tri-axial magnetic feedback sensors with three fluxgate elements, printed circuit board (PCB) electronics unit and an interconnecting harness cable. 

The magnetometer sensor head is deployed about 1 meter away from the lander body by a mortar mechanism operated by a spring. The attitude of the sensor head is determined by a known magnetic signal given by sensor electronics after the deployment.
