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]
