Satellites
CBERS
The China-Brazil Earth Resources Satellite (CBERS)
is a joint project between Brazil and China. CBERS-1 was launched in
October of 1999 and CBERS-2 in October of 2003. These satellites have three cameras:
Wide Field Imager
(WFI),
High resolution CCD Camera
and the
Infrared Multispectral Scanner
(IRMSS). WFI has a ground swath of 900 km in the soil,
which provides a synoptic view with spatial resolution of 260m. The Earth surface is completely covered in about 5 days.
The CCD camera provides images of a 113 km wide strip with 20m spatial resolution and
The IRMSS operates in 4 spectral bands, thus extending the CBERS spectral coverage up to the thermal infrared range. It images a 120 km swath with the resolution of 80m (160m in the thermal channel). In 26 days one obtains a complete Earth coverage that can be correlated with the images of the CCD camera.

LANDSAT
The Landsat (Land Remote Sensing Satellite)
series started in 1972 with the launch of LANDSAT 1. Afterwards, Landsat 2 and 3 were launched, and they all had the all with sensor Multispectral Scanner
MSS which recorded data in 4 spectral bands with 80 meters
of resolution. In addition to the Multispectral Scanner (MSS) instrument, Landsat 4 (and Landsat 5) carried a sensor with improved spectral and spatial resolution. This new instrument was known as the Thematic Mapper (TM).
Since 1974, INPE has been continuosly receiving LANDSAT images
of LANDSAT over the whole brazilian territory, holding a
collection of historical data of the country.

MAPSAR
MAPSAR (Multi-Application Purpose SAR - Synthetic Aperture Radar) is a cooperation project between INPE and
the German Aerospace Center (DLR) for the development and construction of a satellite for day and night Earth surface observation independent
of weather conditions for assessment, management and monitoring natural (renewable and non-renewable) resources. The MAPSAR satellite utilizes a modular concept, consisting of a payload
module and the Brazilian MultiMission Platform (MMP). The MAPSAR payload module includes the SAR sensor, data storage and transmitter,
mechanical structure and thermal control.which has as a payloconstruction tends
as useful load a radar images of SAR (Synthetic Aperture Radar). The
technical viability studies for of MAPSAR are in progress. |
