Camera space made in Brazil will to space in 2010

The launch of the next Satellite Sino-Brazilian Earth Resources (Cbers-3), scheduled for April 2010, will be an important moment not only for the Brazilian space program - because this is the fourth artifact of the series and a good part of it is developed in the country - but also for the Opto Electronics, a company based in San Carlos, in São Paulo State, responsible for the design and fabrication of one of the satellite cameras able to photograph the earth crust.Camera Multispectral
The device, called camera Multispectral MUX, is a significant technological leap for the domestic industry, because it is the first of its kind to be made entirely in the country. The images generated the territories of Brazil and China are intended for environmental monitoring and management of natural resources.
To achieve this done, the picture has a resolution of the earth’s surface, 20 meters in part, responsible for the characteristic sharpness, a parameter that is no small feat, taking into account that the Cbers-3 will be placed in orbit at 800 km, altitude. That amounts to see a train on the surface of the Earth or a fly about 400 meters. The wide range imageada, which is the size of territory seen in a line in the image, is 120 km wide.
National-edge technology
“The making of the Opto MUX meet the guideline of the Brazilian space program to foster the development of cutting-edge technology within the industry of the country, enabling our companies to participate in a competitive international market space,” notes the engineer Mario Selingardi, the technical the project at the National Institute for Space Research (Inpe).
Independence Technology
In addition, the manufacture of this subsystem Cbers-3 for a national partner helps the country to achieve technological independence in highly sensitive areas of strategic point of view. The fa ¬ if current development of the camera is the attainment of functional tests in the engineering model of the MUX. This is a prototype that comes before the model of qualification and equipment that effectively vai fly. The model of engineering should follow up the month of July to China, where vai go through tests in the electrical integration with other systems.
Preliminary Tests
In experiments performed here in Brazil the camera is to undergo tests to confirm that supports the loads of launch and conditions of temperature and vacuum in space, and see if it meets the requirements of ageing and electromagnetic compatibility maintaining its performance. According to the Inpe, the tests, done in laboratory tests and integration of the institute, showed that there was no degradation of performance of optical equipment. “The camera has successfully passed the tests,” says Selingardi of Inpe.
The completion of these trials is an important step in the long journey began in December 2004, when the Opto won the international bidding for construction of the camera. The MUX already started to be designed in the following month and the first phase of work (the preliminary conclusion of the project) was completed at the end of that year. To get idea of the complexity of the project preliminary, just say that it was composed of over 450 documents and 16 thousand pages.
