Skynet is the network of satellites and space vessels orbiting stars and planets in UNME-inhabited solar systems. They monitor conditions in the galaxy on a permanent basis, and are part of the defence ring that could withstand a potential non-human attack on the UNME. The network is used to gather information at any time about any part of the galaxy, and is responsible for many discoveries, aids space travel, and relays Internet, Milinet and Worldnet data over local distances (i.e. within solar systems). 

Skynet is used by the SKYWATCHER program to research the sky. Skynet has also played a vital part in many exploration missions, and is used for triangulation positioning in space.
