| Summary: | A new sensor for measuring low-amplitude magnetic fields that is ideal
for small spacecraft is presented. The novel measurement principle
enables the fabrication of a low-cost sensor with low power
consumption and with measuring capabilities that are comparable to
recent developments for CubeSat applications. The current
magnetometer, a software-modified version of a commercial sensor, is
capable of detecting fields with amplitudes as low as 8.7 nT
at 40 Hz and 2.7 nT at 1 Hz, with
a noise floor of 4 pT∕<msqrt>Hz</msqrt> at 1 Hz. The sensor has
a linear response to less than 3 % over a range of
±100 000 nT. All of these features make the
magneto-inductive principle a promising technology for the development
of magnetic sensors for both space-borne and ground-based applications
to study geomagnetic activity. |
