Magnetic giant magnetoresistance commercial off the shelf for space applications
The increase of complexity and miniaturizing level of Aerospace platforms make use of commercial off the shelf (COTS) components constitute a plausible alternative to the use of military or rad-tolerant components. In this work, giant magnetoresistance commercial sensors are studied to be used as COTS, the next missions to be launched in the framework of the Spanish National Space Program: OPTOS and SEOSAT.
This technology of magnetic sensors is interesting due to their high operating range up to 2 mT and the high temperature dynamic range from -50 up to 150 degrees C. However, in contrast, it presents high hysteresis and nonlinearity, temperature dependence, and poor repeatability. To improve the hysteretic, nonlinear and nonrepetitive behavior, a method consisting of a combination of reset and biasing has been designed and implemented for the +/- 75 mu T linear region centered around 300-375 mu T biasing field.
