A presentation about the MUX, the first satellite camera
entirely developed and produced in Brazil, is one of the landmarks of the celebration
of 51 years of the Brazilian National Institute for Space Research (Instituto
Nacional de Pesquisas Espaciais – INPE), August 10, in São José dos Campos. The
camera, already integrated to the China-Brazil satellite CBERS-3, which will be
launched in China by the end of this year, was designed in 2005 and its
development plays an important role in the Brazilian space program, which is
the qualification of the national industry.
The MUX is a 20-meter resolution and multispectral camera
that records blue, green, red and infrared images. These spectral bands have
well calibrated functions aiming its use in different applications, mainly in
the control of water resources and forestry.
"The primary purpose is to collect images for land
resources monitoring. This includes hydrological, forestry, agricultural, urban
perimeter and mineral control and monitoring, as well as the planning for
sustainable occupation, fires, illegal mining, logging, among others,"
explains Mário Selingardi, project manager of MUX at INPE.
The national company hired by INPE to enable the MUX
design is Opto Eletrônica, from São Carlos (SP), which was able to develop the
115-kg camera, divided in three modules. The camera itself weight 95kg and is
1,1m x 0,55m x 0,8m, where are the lens, the focal plane and the whole
structure and thermal system, radiators, heaters, electronic proximity, etc.
Along with it goes another module, which controls the focal adjustment system,
the thermal control and some auxiliary systems. The system is completed by the
machine where the image is processed and conditioned for transmission to Earth.
Being one of the most sophisticated space projects in
Brazil, MUX demanded thorough and rigorous analysis, because the camera must
support the required lifetime in the harsh environment of space.
CBERS
CBERS (China-Brazil Earth Resources Satellite) Program
satellites are used to monitor deforestation in Brazil, urban sprawl and
agriculture, among other applications. In partnership with China, INPE has
launched three satellites: CBERS-1, in 1999; CBERS-2, in 2003; and CBERS-2B, in
2007.
One of the main remote sensing programs in the world,
next to the American satellite Landsat, the French Spot and the Indian
ResourceSat, CBERS promotes innovation in the national space industry, creating
jobs in a high-tech industry, which is crucial for Brazil.
Due to the policy of free access to images, a pioneering
initiative of INPE, the CBERS images are distributed free of charge to any user
on the internet, which has contributed to the popularization of remote sensing
and to the growth of the Brazilian geo information market.
