The GaoFen-2 Advantage

Large Collection Footprint
With a 45-kilometer swath width, GaoFen-2 covers a massive amount of ground in high resolution.

Affordable Option
GaoFen-2 offers 80-cm resolution imagery at an affordable price, making it ideal for large projects.

Overview & HistoryGaoFen-2 SpecificationsPricing

GaoFen-2 was launched by the China National Space Administration (CNSA) on August 19, 2014. It was an improvement on the 2-meter (m) resolution satellite, GaoFen-1, launched in 2013. GaoFen-2 is part of CNSA’s high-resolution satellite constellation that also includes SuperView-1, collecting 80-centimeter (cm) panchromatic and 3.2-m 4-band multispectral (i.e. blue, green, red and near infrared [NIR]) imagery.

GaoFen-2’s massive 45-kilometer swath width coupled with 80-cm resolution makes it a unique choice for large-scale mapping. This Chinese satellite collects 4-band multispectral data which is ideal for precision agriculture, forestry and spectral analysis.
