On March 4th, China Aerospace released the latest operation and data distribution report for seven satellites in the Gaofen series, with data up to the end of January 2026.
The Gaofen-1, Gaofen-2, Gaofen-3, Gaofen-4, Gaofen-5, Gaofen-6, and Gaofen-7 satellites are included in this statistical analysis.
As of now, the Gaofen-14 series of satellites has been developed, and each satellite has a network of multiple satellites.
The Gaofen series satellites are the core satellites of China's high-resolution Earth observation system, with clear division of labor and complementary networking, covering five categories: optical, radar, hyperspectral, synchronous gaze, and stereoscopic surveying, serving the entire field of land, agriculture, environment, disaster reduction, surveying, and ocean.
Gaofen-1 is a wide coverage and medium resolution optical satellite, serving as the main force for wide coverage surveys and medium resolution optics.
The 2-meter panchromatic/8-meter multispectral data effectively covers 128.79 million square kilometers globally and 9.6 million square kilometers nationwide;
The 16 meter multispectral data effectively covers 303.04 million square kilometers globally and 9.6 million square kilometers nationwide.
Gaofen-2 is the first civilian sub meter level optical satellite in China, responsible for sub meter level fine optical observation tasks.
Effectively covering 167.12 million square kilometers globally and 9.52 million square kilometers nationwide.
Distribute 25561516 scenes of Gaofen-2 satellite data to users.
Gaofen-3 is the only radar satellite in the series, capable of all-weather synthetic aperture radar (SAR) observations.
Effective coverage of 369.34 million square kilometers globally and 9.6 million square kilometers nationwide.
Distribute 42259000 views of Gaofen-3 satellite data to users.
Gaofen-4 is China's first geosynchronous orbit remote sensing satellite used for gaze observation in geosynchronous orbit.
Effective coverage of 92.82 million square kilometers globally and 9.6 million square kilometers nationwide.
A total of 4088402 scenes of Gaofen-4 satellite data were distributed to users.
Gaofen-5 is the only hyperspectral+atmospheric environment dedicated satellite, with the highest spectral resolution and the largest payload
VIMS effectively covers 74.54 million square kilometers worldwide; AHSI effectively covers 29.84 million square kilometers worldwide.
01A Star AHSI effectively covers 32.3 million square kilometers globally and 5.84 million square kilometers nationwide.
A total of 1008729 hyperspectral and full spectrum image data from Gaofen-5 satellite and 1055909 data from 01A satellite were distributed to users, including 896166 AHSI data and 159743 WTI data.
Gaofen-6 is the first precision agriculture observation satellite, which complements the Gaofen-1 network.
The 2-meter panchromatic/8-meter multispectral data effectively covers 166.93 million square kilometers globally and 9.6 million square kilometers nationwide;
The 16 meter multispectral data effectively covers 332.75 million square kilometers globally and 9.6 million square kilometers nationwide.
A total of 3140108 views of Gaofen-6 satellite data were distributed to users, including 1864355 views at 2 meters/8 meters and 1275753 views at 16 meters.
Gaofen-7 is the first civilian sub meter level optical transmission stereoscopic surveying satellite, specializing in three-dimensional surveying.
Effective coverage of 125.4 million square kilometers globally and 9.49 million square kilometers nationwide.
A total of 2296025 scenes of Gaofen-7 satellite data were distributed to users.
PS：
In satellite remote sensing data, "Scene" is the most basic and universal counting unit, referring to a complete and independent standard image block obtained by a satellite through one transit and one continuous imaging.
When a satellite flies along its orbit, sensors continuously scan the ground, forming a long strip of data.
For management, distribution, and processing, standard images will be cut into pieces according to the fixed width of satellite sensors, and each piece is a scene.
Among them, Gaofen-1 Scenic Area is about 32km x 32km, and Gaofen-2 Scenic Area is about 23km x 23km
