Orbit data

GEO-KOMPSAT 2A is an earth observation satellite of the Korea Aerospace Research Institute (KARI).

It was placed in geostationary orbit at 128.2 ° East on December 4, 2018 at 20:37 UTC with an Ariane 5 launcher from the Guiana Space Center (together with GSAT-11 ) .

The three-axis stabilized satellite is equipped with a multispectral camera (AMI) and with magnetic field and particle measuring devices (KSEM) and is intended to provide meteorological and space weather data. It was built on the basis of the GK2 satellite bus from KARI and has a planned service life of ten years.

The 338 kg instrument called AMI (Advanced Meteorological Imager, formerly MI- (Meteorological Imager-II) is a multi-spectral camera built by Harris Corporation , which is based on the ABI camera of the American NOAA GOES-16 satellites. The camera delivers data in 16 bands (4 optical and 12 infrared ) in a wavelength range from 0.47 to 13.21 µm. The resolution is between 500 m in the optical and 2 km for the infrared range with an image area of ​​0.9º × 1.9º Instrument KSEM (Korean Space Environment Monitor) of Kyunghee University consists of a particle detector for the energy range of 100 keV and 2 MeV, a FluxGate magnetometer with a resolution of ± 350 nT in all three spatial directions and a satellite charging monitor that shows the charging current of the satellite in the Measures range of ± 3 pA / cm² due to high-energy particles and warns of a possible electrical discharge in good time.
