China and Brazil plan to launch the CBERS-3 remote sensing satellite in November 2012.

Compatibility tests took place between February 29 and March 7 in China.

On March 30 the Brazilian company 'Opto Eletrônica' sent to China the MUX camera that will be used on the CBERS-3 satellite.This camera will be used to environmental monitoring and remote sensing of natural resources.

MUX mass is 120 kg and has a 20 meter resolution (CBERS-3 will be orbited at 750 km altitude).

That does not look out-of focus but deliberately obscured?

In China, it was completed another stage of CBERS-3 satellite testing before its launch, arranged for the end of the year. Experts of the National Institute for Space Research in Brazil (Instituto Nacional de Pesquisas Espaciais – INPE) and of the China Academy of Space Technology (CAST) have checked the satellite self-compatibility and its electromagnetic compatibility with the launch vehicle.

These tests are necessary to prove that a satellite equipment does not interfere with another one. The simulation on Earth of all the conditions that the satellite will face, since its launch by the end of its life in space, is indispensable due the inability to repair it in orbit.

Before leaving for China, CBERS-3 had all its equipment and subsystems tested at the Integration and Testing Laboratory (LIT) of INPE, in São José dos Campos (SP).

In Brazil, the satellite has undergone several tests for electromagnetic interference and compatibility, vibration, vibracoustic and thermal vacuum further to the mass properties measurement. Now, in China, the final tests to CBERS-3 launching qualification are underway.

Efficiency

The use of satellites allows an efficiently and economic monitoring of environmental changes, both natural and those caused by humans. The observation from space is even more important for large countries such as Brazil and China.

In 1988, both countries established the CBERS Program (China-Brazil Earth Resources Satellite) to join efforts for knowledge on Earth Observation. Three satellites have been launched - CBERS-1, in 1999, CBERS-2, in 2003 and CBERS-2B, in 2007. The fourth satellite, CBERS-3, is scheduled for late 2012, while CBERS-4, for 2014.

Satellite images are essential to collect information about Earth's surface, either necessary to assess global change, forestry, agribusiness development, urban and coastal studies. Satellites are also essential to quickly obtain information about events whose location and occurrence is difficult to predict or access, such as natural disasters (floods, for example), or produced by humans (forest fires, pollution caused by oil spills at sea).

INPE daily distributes hundreds of satellite images by the internet to 1500 public and private institutions in Brazil. The availability of CBERS data allows the development of new applications of remote sensing in Brazil.

Someone claimed that the satellite should be called (at least on the Chinese side) CBERS-1 (03) and not CBERS-3......  :-\

According to http://www.cbers.inpe.br/ingles/news.php?Cod_Noticia=337 the balancing tests of the CBERS-3 satellite have been concluded. Next for CBERS-3 are the acoustic vibration tests.

Will the CBERS-3 launch be delayed?

The launch of the CBERS-3 sino-brazilian remote sensing satellite can be delayed for a few months. The cause? Some failures were identified during tests conducted in China before the satellite could be sent to the launch site. The failures were detected in some DC/DC converters on the satellite power system.

Between 18 and 24 of August, five engineers from the Instituto Nacional de Pesquisas Espaciais (INPE), including the coordinator of the Segmento Espacial do Programa CBERS (CBERS Space Segment), went to the UNited States for various meetings to clear out the non-conformities and the failures of the DC/DC converters (made by the MDI - Modular Devices Incorporated), and to be used on the CBERS-3 and CBERS-4 satellites. These components were brought in 2007 and 2008 and were not affected by the ITAR restrictions.

The CBERS-2 satellite suffered from the same problem on the DC/DC converters before its launch, that led to a delay of several months.

Rui, is there still any chance of this satellite making to orbit in 2012?

Here is a photo of CAST engineers inspecting an infrared camera for CBERS-3 (http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=8807&pid=221863):

I suppose so. I the mean time I'm trying to confirm it.

I think that this article http://miit.ccidnet.com/art/40211/20120926/4311643_1.html talks about the remote sensing missions for this year and I think it says that CBERS-3 is going to be launched until the end of the year. It is in Chinese, maybe you can help?! Thanks!

CBERS-3 launch will probably be delayed by some time (months?) because of the problems that were found on some components of the power subsystem. The delay is being discussed between China and Brazil.

Apparently this launch can still be taking place this year. The electrical tests have been completed and the satellite is now on the environmental tests. A high effort has been taking place to launch CBERS-3 this year with the Brazilian INPE sending more specialists to China to help with the preparations (resulting some delays on the preparations of other Brazilian satellites).

Still, we have to wait and see further developments on this.

I haven't seen any news about this this from Brazilian sources, but the CEOS page (http://database.eohandbook.com/database/missiontable.aspx) is now giving February 2013 as the launch date for this mission. This information needs to be confirmed.

Looks like Xinhua News is disagreeing with you: a news article about Sino-Brazillian co-operation on the CBERS program published on November 3rd still pencils 2012 and 2014 as the launch dates for CBERS-3/4.

That's the information given by CEOS. Like I say, it needs to be confirmed by any of the partners in the project. But, its good news that Xinhua is saying that.

From China.org (in Spanish): ESPECIAL: CBERS, la joya de la corona de la cooperación tecnológica Brasil-China.

So, according to this article CBERS-3 is going to be launch 'in the next weeks'.

That begs the question of whether it or HJ-1C is launching first; unfortunately getting any launch updates from TSLC is notoriously difficult....
