Spain by a Russian launcher it will put in orbit in 2012 the Peace satellite, a spacecraft that every hour and a half will a return to Earth and compared with experts 'bat', because it will be able to take 100 pictures a day, anytime and in any weather condition. Equipped with radar technology, this satellite of nearly 1,400 kilos, will consist of two main modules: a platform or service module and payload or instrument.
The platform, a kind of truck load of recurrent use in other satellites in Germany and serves to place the fuel tanks and solar panels, was built in the country and arrive in Madrid by road today where it will be until the end of the year to incorporate into it the various instruments. It is precisely this whole instrumental part which is 100% English Technology, has detailed EFE Alfonso Martinez, EADS-Casa Espacio and program manager.
The satellite Paz next to civilian use optical satellite-Ingenio is included in the Program National Earth Observation Department of Defense and Industry, Tourism and Trade. Its owner is the business of government services Hisdesat and the main contractor EADS-CASA Espacio.
The contract for construction was signed in November 2008 and Peace will cost 160 million euros (including launch and ground station). With this satellite, a life of five and a half years, Spain has become the first European country with two systems of Earth observation (optical and radar) valid for civilian and military uses, but peace will master user to Defense .
Peace, which addition to the EADS-CASA Espacio English 11 other companies involved, will consist of 12 panels, made these again for 32 elementary antennas, making a total of 384 antennas, each of which can be set independently depending on the objectives susceptible to photograph. When in orbit, about 514 kilometers from Earth, the satellite will fly at seven kilometers per second. According
Alfonso Martínez, Paz is ready to give up fifteen laps on Earth, get about a hundred pictures every day or 300,000 square kilometers, which is like mapping an area the size of Spain every day and a half. Peace has also continued Martinez, an advantage that will be equipped with radar technology, enabling the imaging quality of day and night and in all weathers.
"It's like a bat," stressed the engineer, who explained that the satellite will emit energy and the echo of that energy is thus make out images, Peace downloaded several times a day, when passing through the two stations control, to be located in Maspalomas (Gran Canaria) and Torrejón de Ardoz (Madrid). The data will "crude" ground, which will be processed and may cross with other data, such as mapping.
The program manager has detailed satellite that government, in addition to intelligence and mapping, will serve for border control or evaluation of natural disasters. Over its lifetime carry out periodic correction maneuvers to maintain the orbit altitude selected.
addition to EADS Casa Espacio participate in Peace: Indra Sistemas (construction of the power modules that send and receive its echo); Crisa (electronic units); Rymsa (antennas on the platform), Universidad Politécnica de Cataluña (development of mathematical models of the radar) and NTE-Sener (power equipment). They are also According involved, HV systems, IberEspacio, Inventia Kinetics, Erzia and Caxhinero, each responsible for the integration teams on the ground and Elatesa (manufactures radar antenna elements). Peace will be launched into space with a Dnepr rocket from the Baikonur Cosmodrome in September 2012.
