Tian Hui 1 (also Tian Hui 1A or Mapping Satellite I ) is a Chinese earth observation satellite built by Dong Fang Hong, a company of the China Aerospace Science and Technology Corporation (CASC).
It was brought from the Jiuquan Cosmodrome into a sun-synchronous and polar orbit about 500 km high with a Long March 2D launcher on August 24, 2010 at 9:10 am CEST . According to the Chinese Ministry of Defense, the new satellite will mainly be used for scientific experiments and will continue to be used for evaluating soil resources and for mapping tasks.
Tian Hui 1 is equipped with two different camera systems in the visible and infrared range. The first works with CCD sensors and can take three-dimensional images in the spectral range between 510 and 690 nanometers with a resolution of around 5 meters and a field of view of around 25 degrees. The other has a resolution of around 10 meters and works in the four wavelength ranges (430–520 nm, 520–610 nm, 610–690 nm and 760–900 nm). The swath width of the cameras is around 60 kilometers.
