Brazil and China Testing CBERS-3

Wednesday, June 13, 2012

Compatibility Tests between the China-Brazil satellite CBERS-3 and the images receiving station of Miyun, China, have been successfully completed by the teams of the Brazil’s National Institute for Space Research (Instituto Nacional de Pesquisas Espaciais - INPE), the China Centre for Resources Satellite Data and Application (CRESDA) and China Academy of Space Technology (CAST).

Performed on May 27 and 28 at the Centre for Earth Observation and Digital Earth, electromagnetic compatibility tests were aimed at ensuring the perfect link between the satellite, to be launched in November, and the Chinese receiving station, including the intake, recording and processing system software, developed by the Brazilian enterprise AMS Kepler Engenharia de Sistemas Ltda.

In these tests, the Brazilian (MWT) and Chinese (PIT) subsystems of data transmission are used. Previously recorded images from the Brazilian cameras MUX and WFI and from Chinese cameras PANMUX and IRS are injected into PIT and MWT subsystems and simultaneously transmitted via cable to the station. After reception and demodulation, it is performed the decompression, decoding and real-time display of images. The received data must be the same of sent data.

The tests are important to ensure the images receipt, also to verify the correct decoding and recovering of auxiliary data transmitted along with the image, such as telemetry data from cameras and the orbit and attitude data.

The INPE’s engineers Carlos Gonçalves e Rodolfo Araújo, for Aerospace Electronics Division (AED/ETE), José Bacellar, for Image Processing Division (DPI/OBT) and Leandro Silva, for Integration and Testing laboratory (LIT) have participated in the testing.

The compatibility test between satellite and ground stations in Brazil and China are expected in the Development and Testing Plan of CBERS Program. The validation of Cuiabá station for the CBERS 3 reception was successfully performed in March 2011.

This satellite is the fourth one developed by CBERS Program (China-Brazil Earth Resources Satellite; in portuguese, Satélite Sino-Brasileiro de Recursos Terrestres), under the partnership with China for over 20 years, which ensured both countries mastering the remote sensing for Earth observation technology.
