Use

ATVs are intended to be launched every 17 months in order to resupply the International Space Station. They use GPS and a star tracker to automatically rendezvous with the Space Station. At a distance of 249 m, the ATV computers use videometer and telegoniometer data for final approach and docking manoeuvres. The actual docking to Zvezda is fully automatic. If there are any last-minute problems, a pre-programmed sequence of anti-collision manoeuvres, fully independent of the main navigation system, can be activated by the flight engineers

 aboard the station.

With the ATV docked, the station crew enters the cargo section and removes the payload. The ATV's liquid tanks are connected to the station's plumbing and discharge their contents. The station crew manually releases air components directly into the ISS’s atmosphere. For up to six months, the ATV, mostly in dormant mode, remains attached to the ISS with the hatch remaining open. The crew then steadily fills the cargo section with the station's waste. At intervals of 10 to 45 days, the ATV’s thrusters are used to boost the station's altitude.

Once its mission is accomplished, the ATV, filled with up to 6.5 tonnes of waste, separates. Its thrusters move the spacecraft out of orbit (de-orbit) and place it on a steep flight path to perform a controlled destructive re-entry

Cargo Ascent and Return Vehicle: The CARV would deliver a redesigned capsule, capable of bringing back payload from orbit. It could be installed in place of the ATV pressurized cargo hold.

The ARD was launched on October 21, 1998, and was released shortly after separation of the launcher's cryogenic main stage 12 minutes after lift-off from the Guiana Space Centre, Europe's spaceport...

     and related projects. The budget for this stage of the ATV overhaul would reportedly be €300 million.
  • The second stage would adapt the then existing capsule to be able to transport people safely as well as upgrade the propulsion and other systems in the service module and would last 4 to 5 years at a cost of "a couple of billion (€)" according to a senior Astrium representative.

Subsequent activity

In November 2008, ESA ministers budgeted for a feasibility study into developing a re-entry capsule for the ATV, a requirement for developing either a cargo return capacity or a manned version of the ATV. ESA signed a €21 million study contract with EADS Astrium on 7 July 2009. The ARV effort was discontinued after the B1 stage due to fiscal constraints resulting from the Late-2000s financial crisis

. In May 2011 the ESA director general announced a possible collaboration with NASA to work on a successor to the ATV. A proposal is to be presented to ESA members in 2012. This is likely to involve a design which utilises the ATV derived service module and the NASA MPCV
