If the ATV is able to dock automatically - that is to say without external assistance - to the International Space Station safely, it's because he used a particular software theft of great complexity associated with a set of sensors which we will explain the functions.

If everyone knows the Russian Docking mechanism of the ATC, the center of the craft, very few know what do the other devices distributed around the mechanism. coloring pages for kids Note the presence of two sensors stellar (1) which allows the module to detect relative to the position of the stars . Among them are the crew visual target (2 and 3). The first target (2) is no longer used since the camera mounted on the rear of the service module of the ISS Zvezda (where dock ATV) is down. It is not removable and can not be changed. As to the second target, the 3, it works. To avoid distorting the two, the second camera is removable and was also replaced.

Suit Kurs antenna system (4) which is only used to provide distance information to the crew on board the ISS. And it has data radioed to the crew that are independent of those used by the ATC at its automatic navigation. There are also two navigation lights (5) allow the crew ( via the camera looking at the approach ATC) to have an idea, even rude, the orientation of the device relative to the station orbit when not illuminated by the sun . Under the lashing mechanism, two télégoniomètres (6) function as pistols laser to measure the distance and relative velocity of the target (ISS) with its retroreflectors installed on the back of the station. They also measure the angular direction relative to the target, considering the angles azimuth and elevation of the return direction of the laser beams.

Today is the last scheduled to dock the ATV of the European Space Agency to the International Space Station. The event, captured by five cameras, two of them located outside the ISS, will be broadcast live by CNES in unprecedented conditions.

Fifth and final mission to resupply ISS ATV of the European Space Agency.  With Columbus and after the March 2008, February 2011, March 2012 and June 2013, these five missions represent the annual contribution ESA must pay for the use of the Space Station ($ 150 million).  © Esa, Nasa

Since its launch on July 30, the Guiana Space Centre by an Ariane 5, the ATV-5 Georges Lemaître vogue toward the International Space Station (ISS). free coloring pages It is now 15: 30 pm (Paris time), he has finally dock at the orbital complex, on board, some 6.7 tons of cargo. Remaining there until January 25, it will be repeatedly asked to raise the orbit and serve as pressurized module.

The site of the CNES broadcast live through five cameras, docking of the ATV . Also a first and a last, since this is its  ultimate mission . The antenna jack is announced at 14: 45 am (Paris time).

While the main video stream broadcast a broadcast one hour commented on the subject, you can monitor the operations from the station with two onboard cameras, one Russian and one American, placed outside. Another camera will take us to the heart of the event, the control center of the Centre National d'Etudes Spatiales (CNES) in Toulouse. A final video stream will reveal in real time and image synthesis company, the progress of the ATV until its final approach.
