The ASO-S satellite will operate in a sun-synchronous orbit at an altitude of about 720km and conduct long-term continuous observations of the sun, with a design life of four years. The satellite payloads include the Full-Disc Vector Magnetograph (FMG), the Hard X-Ray Imager (HXI) and the Lyman-Alpha Solar Telescope (LST).
Full-disc vector MagnetoGraph(FMG)
FMG schematic
The Full-disk vector MagneoGraph (FMG) measures the magnetic fields of the photosphere over the entire solar disk. In normal mode, the sensitivities are 5G and 150G for longitudinal and transverse component, respectively.
Hard X-ray Imager (HXI)
HXI schematic
The Hard X-ray Imager (HXI) is designed for solar flare observations,aiming to image the full solar disk in the high-energy range of 30 to 200 keV with good energy resolution.
Lyman-alpha Solar Telescope(LST)
LST schematic
Lyman-alpha Solar Telescope(LST) is to image the Sun from the disk center to 1.2 solar radii and the inner solar corona from 1.1 to 2.5 solar radii in both the Lyman–alpha waveband (121.6±7.5nm) and white-ligh.
