TH 1 (Tianhui-1 = "Sky drawing") is a Chinese stereo-topographic mapping satellite operated by the People’s Liberation Army (PLA). The satellites are built by the Hangtian Dongfanghong Weixing Corporation and the China Aerospace Science and Technology Corporation and the Chinese Academy of Space Technology (CAST). The satellites operate on a 500 km circular sun synchronous orbit. Electrical power is provided by two deployable solar panels that is stored on onboard batteries. They are equipped with a three-dimensional survey camera and a CCD camera with a ground resolution of 5 meters, spectral region of 0.51 µm to 0.69 µm and with a camera angle of 25 degrees. Also on board is a multi-spectral camera with a ground resolution of 10 meters operating in four spectral bands of 0.43 µm to 0.52 µm, 0.52 µm to 0.61 µm, 0.61 µm to 0.69 µm, and 0.76 µm to 0.90 µm. The swath width of the cameras is 60 kilometers wide.
Sun-Synchronous OrbitNauka (which means "Science" in Russian), also known as Multipurpose Laboratory Module (MLM), is a new module of the russian segment of the ISS. It will dock at Zvezda's nadir port, replacing the Pirs module occupying it since September 2001. The Nauka module is designed to be used for experiments, docking and cargo as well as serve as a crew work and rest area. It is equipped with full guidance and navigation control including engines and an attitude control system that can be used as a backup by the ISS. The Nauka module also brings the European Robotic Arm, for which a spare elbow joint was already launched in 2010, to the orbital laboratory.
Low Earth OrbitThe Ningxin-1 satellites (also called Zhongzi) are a series of Chinese commercial remote sensing satellite owned by Ningxia Jingui Information Technology Co. Ltd. The satellites were built by DFH Satellite Co. Ltd of CAST. They have been reported to be a commercial operated global EM spectrum signal monitoring satellite system (SIGINT).
Low Earth OrbitTianlian 1, also known as Tian Lian 1, TL-1, and CTDRS-1 is a Chinese data tracking and relay communications satellite series. Based on the DFH-3 satellite bus, it will provide communication coverage for manned Shenzhou missions, from Shenzhou 7 onwards. Functionally, it is similar to the United States Tracking and Data Relay Satellite System.
