Abstract:

A low-resource anisotropic magnetoresistance-based vector magnetometer for space science applications is presented. The proposed vector magnetometer can detect magnetic fields in a range of ±65000 nT, has a –3 dB bandwidth of DC to 10 Hz, and a noise power spectral density of ≤0.2 nT/Hz1/2@1 Hz. Furthermore, the device has a non-linearity error of ≤3.6%oo over the entire range and non-orthogonality error of ≤1.2%oo. The vector magnetometer was equip on a Chinese Feng-Yun meteorological satellite (FY-3E) whose orbit was a sun synchronous orbit. The first in-flight science results show that the sensor can detect transient physical signals with amplitudes of 20–60 nT.

Key words: low-resource magnetoresistance sensor, vector magnetometer, space science applications
