The Tianhui-1 satellites are built by the Hangtian Dongfanghong Weixing Corporation and the Chinese Academy of Space Technology. They use two three-segment deployable solar arrays for power generation and have precise attitude control and pointing capability. The satellite payload is comprised of a three-dimensional imaging system for the acquisition of stereo imagery and a multi-band camera.

The stereo imager has a field of view of 25 degrees and achieves a ground resolution of five meters. It is sensitive across a wavelength range of 510 to 690 nanometers. The multi-band camera reaches a resolution of ten meters and covers four spectral channels in the blue, green, red and near infrared bands. Both imaging systems are covering a ground swath of 60 Kilometers.
