Ocean Observation Satellite

Overseas Ocean Satellite

Introducing overseas ocean satellites.

Overview of Overseas Ocean Satellites

Overseas Ocean Satellite

The Korea Ocean Satellite Center has built X-band and L-band antennas since 1996 before Geostationary Ocean Color Imager (GOCI) was launched and directly received the data of overseas polar-orbiting satellites that observe the Earth.

The ocean color data among overseas satellite data are used to develop and calibrate/validate the algorithms of the GOCI, and the data other than ocean color data such as sea surface temperature are used for technology development.

Reception Status and Area

About sensors

AVHRR

In case of AVHRR, starting from TIROS-N in 1978, NOAA-6, NOAA-7, and NOAA-8 were launched in Jun. 27, 1979, Jun. 1981, and 1983,
respectively. Currently, NOAA-18 and NOAA-19 are being operated. These satellites have visible light, near-infrared ray,
and infrared light sensors to observe the Earth and monitor environments. Go

MODIS

MODIS is the main sensor of EOS that provides data based on the dynamics of the biosphere of the Earth.
It is a multi-purpose sensor that can be applied to sea, land, and atmosphere. This sensor was first built in the Terra in Aug.
1999 and additionally built in the Aqua in May 2002. Go

VIIRS

VIIRS was built in NPP and JPSS-1 on Oct. 28, 2011.
This Earth observation satellite of NASA is for ocean observation among the five sensors of NPP.
VIIRS was developed to take over the roles of MODIS and AVHRR, which have been operated for years. Go
