Dongfanghong II was a primary television satellite used by China during the later part of the 20th century. It was developed at the Chinese Academy of Space Technology (CAST) and had a design life 4.5 years. The first satellite in this group was launched into a geosynchronous orbit on April 8, 1984. Broadcasts from these satellites were able to cover all of China and some neighboring regions.[citation needed]

Three satellites orbited in geosynchronous orbits at 87.5, 110.5, and 98 degrees east. A fourth satellite failed to achieve a stable orbit due to a problem with the third stage.[1]

Satellite design[edit]

The satellite was cylindrical with a height of 8.5 m (28 ft), a diameter of 2.1 m (6 ft 11 in) and weighed 441 kilograms (972 lb).

The Dongfanghong II A satellite used a parabolic communications antenna mounted to the top of the satellite for broadcast purposes. The antenna could be rotated to keep it aligned with the Earth. Twenty-thousand solar cells were mounted to the satellite to provide power. This was China's first successful use of photovoltaic technology. [2]
