RESURS-DK1 Satellite

"Resurs-DK" Space Complex

Resurs-DK1 space complex was developed and produce in accordance with Federal Space Program of Russia against Federal Space Agency order.

Resurs-DK1 space complex is effective SC which allows obtaining highly detailed multispectral images of the Earth surface of high quality. The complex is created with the participation of wide range of research institutions, design bureaus and manufacturing plants of Russian federation. SRC-Progress is a main developer of the complex.

Application area of Resurs-DK1 and tasks which are sold:

Resurs-DK1 is meant for multizonal Earth remote sensing and for downlink of near-real time highly informative images vie radio channel in order to solve the following tasks:

different electromagnetic radiation spectrum range providing operative downlink by radio-channel directly to ground receiving station and further presentation to a wide range of users both Russian and foreign after thematic processing.

Information, received by "Resurs-DK" Complex can be used for various research and economic problem solution, including:

· information support of rational nature management and economic activities of state structures, subjects of the Russian Federation and some other subjects and structures in the field of agriculture and soil science, geology, land use;

· creation and updating of general and thematic topographic plans and mapping;

· information support in the field of ecology and environmental protection;

· solution of task for the benefit of Ministry of Emergency Situations and some other organizations;

Obtained data can be used for international cooperation between Russia and some other countries which are interested in environmental protection and task solutions in the field of Earth remote sensing. It can also be used for information support of foreign customers under intergovernmental agreement as well as on a commercial basis.
