GF-1 SATELLITES

4 Satellites, 2 m Resolution, Optical

GF-1 (short for GaoFen-1) constellation is composed of 4 satellites. GF-1 is equipped with two 2 m panchromatic and 8 m multispectral cameras (PMC), and four wide-field imagers (WFI) with 16 m multi-spectral resolution and a combined swath of 800 km. The satellite allows the collection in PMC and WFI modes both simultaneously and separately. GF-1B, C and D are single-camera sensors, collecting 2 m panchromatic and 8 m multispectral resolution data. When the four satellites work as a constellation, they provide massive collection efficiently, and cover the whole planet only for 11 days, revisiting at any place on the Earth on a daily base.
