TOMSK, Apr 11 – RIA Tomsk. Scientists of the Tomsk Research Institute of Atmospheric Optics SB RAS till 2021 plan to create the first Russian lidar for calculation of coordinates of a landing of uncontrolled spacecrafts directly from space, while now there is no similar system at all, the director of institute Gennady Matviyenko has told on Monday.
"Such information in operational scale is necessary, to throw off uncontrolled spacecrafts to the Earth precisely. It has turned out that there are atmosphere models, but anyway there are big mistakes. In a stage of creation of a new lidar (The device which allows by means of laser radiation to receive and process data about objects at a great distance. – Ed.) is our institute", – Matviyenko has told.
He has explained that the device will be intended, first of all, for descent of uncontrolled cargo modules from the International Space Station (ISS). In similar modules freight is delivered both as to an orbit, and from an orbit to the Earth – for example, transfer data of scientific researches.According to him, now trajectories of a landing of similar objects are calculated on the basis of atmosphere models. However ground-based Russian lidars in Tomsk, Yakutia and on Kamchatka show that these data can not correspond to reality for 30-40%. As a result, the device at a landing can "miss" on hundreds of kilometers.
Matviyenko has noted that the space lidar is necessary, as the orbit of ISS doesn't get to a zone of control of any similar land device. Now in the world there are no other devices which would allow to obtain so exact data for calculation of the place of modules landing.
Matviyenko has noted that as the customer of the device acts one of leading enterprises of space branch of the Russian Federation – S.P Korolev Rocket and Space Corporation "Energia". It is supposed that lidar will be put into an orbit in 2019-2021 and will settle down in the Russian ISS segment. He hasn't specified the planned amounts of financing.
