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.
