In December 2013, ESA representatives launched the Gaia Observatory and are now studying the Milky Way with it. This allowed us to create one of the most accurate star charts in our galaxy.
The control of the spacecraft is the responsibility of scientists in Darmstadt (Germany), sending commands, as well as receiving information about the status and functioning of the technology. They also plan and carry out routine maneuvers that are needed for the device to remain at a distance of 1.5 million km.
In the picture you can see the engineers working on the mission’s aviation radio. These are devices, hardware and software of the spacecraft, allowing to control it from the Earth.
The device is used for simulations with high accuracy, which helps test procedures and software still on Earth.
