|
|
|
| <p><strong>Hongyan 1</strong> is a prototype satellite for CASC's +300 satellite Hongyan broad-band LEO communications constellation.</p>
|
|
|
| <p>The first Hongyan satellite was launched on a <a href="../doc_lau_det/cz-2d-2-yz3.htm">CZ-2D (2) YZ-3</a> rocket and went into a 1100-kilometer orbit to test L- and Ka-band communications technologies.</p>
|
|
|
| <p>Nine Hongyan satellites were be launched by 2020 to test the system, which ultimately will comprise 320 satellites. A factory able to produce as many as 130 Hongyan satellites a year has been built in the Chinese port city of Tianjin.</p>
|
|
|
| <p>Despite of massive deployment plans, no further launches followed. In 2020, the project was merged with the competing <a href="hongyun-1.htm">Hongyun</a> to a new mega constellation project called Guowang.</p>
