The ZY-3 (Ziyuan-3, 'Resource-3') series represents China's first high-resolution, stereoscopic mapping satellites for civilian use. The second satellite is managed by the Satellite Surveying and Mapping Application Center (SASMAC). The imaging payload consists of a three-line camera array and a multispectral imager. The three-line panchromatic camera array to acquire stereoscopic imagery consists of three telescopic cameras with one oriented to the nadir and the other two each offset by 22° forward and backward in flight direction. The stereo mapping camera of ZY-3 has a resolution of 2.1 m for the nadir camera, and 2.6 m for the offset cameras. The swath width is 51 km. The multispectral imager for environmental and vegetation monitoring consists of a three-mirror telescope and a cooled detector system sensitive to four wavelength bands to capture full-color imagery as well as near-infrared data. The ground resolution of this system is 5.8 m.
Sun-Synchronous OrbitDEAR-5 is a commercial in-orbit payload and micro-gravity experiments hosting spacecraft developed by Chinese commercial company AZSPACE for various civilian customers, with capability to carry a maximum of 300 kg of payload for up to 1 year in orbit.
Low Earth OrbitTwo technology demonstration satellites for satellite transmissions of signals for the VHF Data Exchange System (VDES), a successor to the current Automatic Identification System (AIS) on ships and maritime vessels for traffic management at sea with higher bandwidth on new frequencies for secure communications and e-navigation. This project is a joint effort by the China Ministry of Transport's China Transport Telecommunications Information Center and SpaceSail, operator of the Qianfan/G60 constellation.
