ZiYuan-3 02 (ZY-3 02) is a Chinese satellite, launched on the 30th of May 2016, the second satellite of the ZiYuan III series. ZY-3 02 can provide high-resolution stereoscopic survey. Unlike its predecessor – ZiYuan III-1 satellite – it has onboard improved optical system, which allows achieving 2,7 m resolution (ZY-3 01 had 3,5 m resolution).

The satellite carries three high-resolution panchromatic cameras and 1 infrared multispectral scanner (IRMSS). The panchromatic cameras are positioned at the front-viewing, vertical-viewing and rear-viewing positions, and they collect imagery of the Earth from different perspectives at the same time, allowing precise determination of the exact locations of different areas of interest on the Earth, resulting in ideal production of large-scale maps. At the same time, the payloads can also provide high-resolution infrared and stereoscopic images to satisfy the demands of the users from resource mapping, environmental surveying, disaster monitoring, city planning and national security segments.
