Network of space-tracking stations of the European Space Agency
The small and fast antenna can be used for Launch and Early Orbit Phases and for tracking rain, Vega and Soyuz launchers operated from ESA's Spaceport at Kourou, French Guiana. It was built to take over some capabilities of the Perth station. The antenna has got a larger field of view and can locate spacecraft after launch.

The new 35m antenna is currently under construction and should become operational in mid-2025. It can support the latest missions like Bepi Colombo, Juice or Euclid by receiving in higher frequency bands than NNO-1.
Redu is part of the ESTRACK network since the beginning. The site hosts more than 40 antennas including antennas for telecommunication satellites and Galileo. The current ESTRACK antenna was built in 1995 and is currently used for Galileo TT&C.
The station in Santa-Maria can be used to track Ariane launches with medium inclination and it is also capable of tracking Vega and Soyuz launchers operated from ESA's Spaceport at Kourou, French Guiana.
The ESTRACK network consists of several ground station around the world. Some of them are owned by ESA itself while others are owned by commercial and other institutional operators. The core stations as well as all of the connections to the missions are operated through the Network Operations Centre at ESOC.
Core Ground Stations
The Core ESTRACK network is composed of seven ESA-owned ground stations. Four of the stations are used for tracking satellites and launchers near Earth and three are used for tracking deep-space probes. Details about the stations are shown in the next section.
Augmented Network
Service contracts with commercially operated ground stations allows the network to track satellites that aren't in view of the ESA owned ground stations. The most relevant operators include KSAT, SSC and Goonhilly Satellite Earth Station. The composition is constantly changing and for every launch different stations may be used.
Cooperation agreements with international partners further enhance the network. Some of these are Deep Space Stations and therefore can offer services that are not be provided by commercial operators. The agreements are usually made on an exchange of services or as a contribution to a mission, meaning that no exchange of funds is part of the agreement.
