The magnetic sensor head is a Wheatstone bridge formed by four anisotropic magnetoresistances (AMR). AMR sensors are an adequate choice for medium- to high-sensitivity (~3 mV/V/G) and resolution (~ 3 ¿G) requirements, mostly due to their low weight and volume that are so interesting for the aerospace industry. The whole system installed in NANOSAT-01 is formed by two biaxial sensors with two redundant PCBs (printed circuit boards) of RAD-HARD proximity electronics, which conditions the AMR output signal, measure the temperature, and resets the AMR. This magnetic sensor belongs to the attitude control system (ACS) of the satellite.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/Magnetic SensorsSmall Satellitesinfo:eu-repo/semantics/article10.1109/TAES.2010.54616401557-9603info:eu-repo/semantics/openAccess
