context_page_description: CSES is a Chinese–Italian space mission dedicated to monitoring electromagnetic field and waves, plasma parameters and particle fluxes induced by natural sources and artificial emitters in the near-Earth space. Austria contributes to one of the magnetometers.
  The CSES Satellite was launched from the Jiuquan Satellite Launch Center in the Gobi desert on February 2, 2018. The expected mission lifetime is of 5 years.
context_section_description: CSES is a 3-axes stabilized satellite, based on the Chinese CAST2000 platform, with a mass of about 730 kg and a peak of power consumption of about 900 W. Scientific data will be transmitted in X-band at 120 Mbit/s. The orbit is circular Sun-synchronous, altitude of about 500 km, inclination of about 98°, descending node at 14:00 LT.
  The CSES payload includes: two particle detectors (the High-Energy Particle Detectors (HEPD) and the High-Energy Particle Package (HEPP)) to measure flux, energy spectrum, type and direction of impinging particles; a Search-Coil Magnetometer (SCM) and a High Precision Magnetometer (HPM) to measure the components and the total intensity of the magnetic field, respectively; a four probes Electric Field Detector (EFD) to measure the electric field components in a wide frequencies range; a Plasma analyzer Package (PAP) and a Langmuir probe (LP) to measure plasma parameters; a GNSS Occultation Receiver and a Tri-Band Beacon to measure the density of electrons and to perform ionospheric tomography 
  The High Precision Magnetometer (HPM) is developed in cooperation between the National Space Science Center (NSSC) of the Chinese Academy of Sciences, the Space Research Institute (IWF) of the Austrian Academy of Sciences (ÖAW) and the Institute of Experimental Physics (IEP) of the Graz University of Technology. NSSC is responsible for the dual sensor fluxgate magnetometer, the instrument processor and the power supply unit, while IWF and IEP participate with a scalar magnetometer (CDSM).
  Each instrument will collect data in two operating modes: ‘‘burst mode’’,  activated when the satellite passes over China and the more seismic regions of the Earth, and ‘‘survey mode” for other areas of the Planet.
  There are two different orbital working zones: the ‘‘payload operating zone’’, for geomagnetic latitudes between -65° and +65° (where the instruments will collect data) and the ‘‘platform adjustment zone’’, at higher latitudes (where all detectors will be switched off to perform the satellite attitude control and the orbital maintenance activities).
