MGFOperational
+/-0.06 nT
The MGF consists of dual, tri-axial fluxgate magnetometers mounted on an 80-cm carbon fibre boom for measurements of magnetic field perturbations to a precision of 0.0625 nanotesla, from which to infer small-scale field-aligned currents. The MGF is turned on an average of 20% of the time, following a schedule devised by the science team.n/a
SEMPOperationalA suite that contains energetic particle detectors, magnetometer, and space weather impact detectors, among which, the energetic particle detectors measure high energy protons and high energy electrons with two probes. Particle flux detection is performed in multiple directions with a number of probes mounted toward different orientation on the three-axis stabilized spacecraft. The space weather impact detectors measure radiation dosage, electrification at the surface and deep inside the spacecraft. It’s the first time China put space weather impact and space environment detectors on the same geostationary platform.n/a
