Gyeonggi's climate satellite
is already in orbit

On 29 November 2025, Gyeonggi Climate Satellite No.1 was launched successfully.
From space it records the changes across Gyeonggi-do, for us and for the future.

WHY — Why a climate satellite

Gyeonggi-do needed
a climate satellite of its own

01

Responding to the climate crisis
required scientific data

Acting ahead of the climate crisis and shaping policy for residents calls for decisions based on scientific data, not on forecasts or intuition. Gyeonggi-do therefore introduced its own small satellites to put data-driven administration into practice on the basis of accurate observation.

02

Observing even invisible methane and leading global climate cooperation

Methane is a greenhouse gas with a warming potential dozens of times higher than carbon dioxide. With the first independent observation system run by a local government, Gyeonggi-do tracks and measures methane sources precisely and helps lead the global climate response.

03

Opening climate data to grow an innovative climate-tech ecosystem

Climate data is a public asset that everyone should share.
Gyeonggi-do opens its data for free use and supports the growth of climate tech and future industries.

GYEONGGISAT — Three climate satellites

Three eyes
watching over Gyeonggi-do

Three satellites in total — one optical satellite and two greenhouse gas observation satellites, each operating on its own mission for three years.

Gyeonggi Climate Satellite No.1 (optical) In operation
Optical observation · launched 29 Nov 2025

No.1 (Optical)

The high-resolution satellite that sees Gyeonggi-do most clearly

Spatial resolution1.5 m
Swath width14 × 40 km
OrbitSun-synchronous
CoverageAll of Gyeonggi-do
A resolution of 1.5 m is fine enough to tell one car apart on a road.
Prototype of Gyeonggi Climate Satellite No.2 In operation
Greenhouse gas observation · launched Oct 2, 2026

No.2 (Greenhouse gas observation)

A greenhouse gas satellite that detects methane emissions precisely

Spatial resolution25 m
Swath width10.5 × 10.5 km
Methane detection100 kg/h and above
CoverageIndustrial complexes, power plants and more
It can even find methane leaks that are invisible to the eye.
No.3 (same series as No.2, to be built)
In preparation
Greenhouse gas observation · to be built

No.3 (Greenhouse gas observation)

A follow-on satellite that forms a constellation with No.2 to shorten the revisit time

Spatial resolution25 m
Swath width10.5 × 10.5 km
Methane detection100 kg/h and above
CoverageIndustrial complexes, power plants and more
When the two satellites fly together, the same place
can be seen more often and in finer detail.

MISSIONS — What the satellites do

What a climate satellite does
goes much further

Disasters, methane, urban change, policy — the uses of the Gyeonggi Climate Satellite keep growing.
Here are five of the main ones.

Rapid support when climate disasters strike

When a wildfire, landslide or flood occurs in Gyeonggi-do, the area is imaged and the damage is assessed quickly with AI deep learning. Damage is detected within a short time after the event, areas that are hard or dangerous to reach are observed safely, and before-and-after damage is compared with objective, transparent data.
