Pujiang-1, also known as PJ-1, is a Chinese technology demonstration satellite [1] designed to promote the construction of smart cities in China. [4] PJ-1 also monitors weather, traffic and population density of a city. It is the first Chinese satellite that uses 3D printing for the titanium structure of its antenna. [5] It also features a Wi-Fi router providing a communication network between satellites. [3]

Ariane 5 is a retired European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It was launched from the Centre Spatial Guyanais (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development.

Yaogan is the cover name used by the People's Republic of China to refer to its military reconnaissance satellites. Yaogan satellites are largely known to primarily support the People's Liberation Army's Strategic Support Force (PLASSF), formerly the Aerospace Reconnaissance Bureau of the Second Department of the General Staff. The Yaogan program is the successor to the Fanhui Shi Weixing (FSW) recoverable reconnaissance satellite program but, unlike its predecessor, includes a variety of classes utilizing various means of remote sensing such as optical reconnaissance, synthetic-aperture radar (SAR), and electronic intelligence (ELINT) for maritime surveillance. Yaogan satellites have been launched from the Taiyuan Satellite Launch Center (TSLC) in Shanxi province, the Jiuquan Satellite Launch Center (JSLC) in Inner Mongolia, Xichang Satellite Launch Center (XSLC) in Sichuan province and the Wenchang Space Launch Site (WSLS) in Hainan province.
