Title: CBERS-4A, ETRSS-1 and others - CZ-4B - Taiyuan - December 20, 2019 (03:22 UTC)
Post by: Satori on 05/01/2015 03:03 pm
On April 24, 2015, China and Brazil have signed the agreemnet for the construction of CBERS-4A. Launch is schedule for 2018.

At the end of 2015 the two parts should have ready the studies for CBERS-5 and CBERS-6. No firm launch dates yet for these two sats.

I think the thread title should be CBERS-4B, not CBERS-4A.

No. The satellite designation is CBERS-4A: http://www.inpe.br/noticias/noticia.php?Cod_Noticia=3861 (in Portuguese).

China to launch Ethiopian satellite ETRSS-1 by years end.

I'm assuming that this launch will be similar to previous remote sensing satellites launched by China in collaboration with other countries. So, possibly a CZ-2D will be used out of Jiuquan.

A further hypothesis:
Could ETRSS-1 and these three MinoSpace satellites, MN50-01, MN10-03, and MN10-04, be four secondary payloads on a December 2019 CZ-4B launch from JSLC, with the primary, more massive payload TBA?

Cross-post, including slide image:
Launch schedule by MinoSpace until 2021. The Dec 2019 CZ-4B launch is very likely from JSLC.

The old link hasn't been updated since May (http://www.lit.inpe.br/aovivo) and I haven't found a single government/space agency site/youtube channel that even mention words webcast/broadcast/live transmission in relation to the launch. Brazilian or Ethiopian.

Quick edit: no video live transmissions, I mean, some posts (https://www.agoravale.com.br/noticias/Informativo/satelite-cbers-04a-sera-lancado-no-inicio-da-madrugada-desta-sexta-feira) do mention an audio feed via phone call from Taiyuan but it won't be publicly accessible.

"The CAMSAT CAS-6 amateur radio payload is set for launch on Friday, December 20, at 0321 UTC from the Taiyuan Satellite Launch Center, piggybacked on a TIANQIN-1 technology test satellite, using a CZ-4B launch vehicle. The primary launch payload is the China-Brazil Earth Resources Satellite CBERS-4A.

The microsatellite, to be known as CAS-6/TIANQIN-1..."

So, Tianqin-1 is other designation for CAS-6 (?)

So as I understand this and similar links, the satellite owner will be
国智恒北斗好年景农业科技有限公司
(Guozhiheng Beidou haonianjing Agricultural Technology Co.) of Zhengzhou City, Henan  www.bdsagr.com
and the manufacturer is
西安中科天塔科技股份有限公司
Xi'an Zhongke Tianta Tech.Co.Ltd, in Xi'an.  I note that the street address of this company is identical to that

the video was indeed a video mix of prerecorded footage and animations but the muffled barely audible voice occasionally was a phone line from Taiyuan giving updates.

New commercial satellite launched in north China
XI'AN, Dec. 20 (Xinhua) -- A new commercial satellite was successfully launched from Taiyuan Satellite Launch Center in north China's Shanxi Province Friday.
The "BDSAGR-1" satellite has entered its scheduled orbit and is expected to provide accurate remote sensing data on crops in the river basins in north China and help modernize and digitalize China's agricultural industry.
The satellite belongs to the first phase of the "Guozhiheng Agricultural Remote Sensing Satellite Constellation" project jointly engineered by GasTianta and GZH-HNJ BDS AGR Co., Ltd.
Zeng Weigang, general manager of GasTianta, said the satellite was designed to operate in a sun-synchronous orbit with an orbit period of 96 minutes.
Zeng added that the project will eventually form a remote sensing satellite constellation consisting of 40 satellites covering the whole country.
"As a traditional agricultural country, there is still much room for improvement in the application of remote sensing satellites in China's agricultural field," said Zeng.
"We will continue to deepen the R&D and marketing of commercial aerospace technology and explore the application of remote sensing satellite technology in areas such as agricultural resources investigation, crop monitoring, disaster monitoring and food safety traceability," he added.

What is the first word/phrase on step 13 of the launch sequence? (ideally pasting the Kanji, I can't copy from the image to google translate).
I assume it refers to the two NUDT satellites but I can't make it out.

I'm having trouble matching the brochure to the sats. It looks like the sequence is:

T+798  CBERS 4A sep
T+833  Upper adapter sep
T+868  medium-large payload Tianqin 1 sep
T+905  medium-small payloads NUDT sats?  and Tianyan-02 sep
T+947  small payloads Ethiopia, Floripa, Tianyan-01, and Guozhi.. (Weilai1R) sep

But this doesn't seem consistent with the rest of the discussion about the payloads which should
be 
medium size:   ETRSS, Guozhi/Weilai-1R, Yizheng/Tianyan-01
medium-small: Tianqin-1
small :      Floripa, Tianyan-02
unknown but probably small:  NUDT sats Yuheng and Shuntian

Clarification sought :-)

See below. CZ-4B s/n Y44 was used for this launch.
I can translate the whole brochure at others' request.

What is the first word/phrase on step 13 of the launch sequence? (ideally pasting the Kanji, I can't copy from the image to google translate).
I assume it refers to the two NUDT satellites but I can't make it out.

That's correct. "Orbital Router Demonstration Twin Satellites" is the name given to them two here for NUDT's satellites.

I'm having trouble matching the brochure to the sats. It looks like the sequence is:

T+798  CBERS 4A sep
T+833  Upper adapter sep
T+868  medium-large payload Tianqin 1 sep
T+905  medium-small payloads NUDT sats?  and Tianyan-02 sep
T+947  small payloads Ethiopia, Floripa, Tianyan-01, and Guozhi.. (Weilai1R) sep

But this doesn't seem consistent with the rest of the discussion about the payloads which should
be 
medium size:   ETRSS, Guozhi/Weilai-1R, Yizheng/Tianyan-01
medium-small: Tianqin-1
small :      Floripa, Tianyan-02
unknown but probably small:  NUDT sats Yuheng and Shuntian

Clarification sought :-)

Your satellite separation is correct. I won't trust the size of the satellite models used other than the number of satellites....  ;)

I hear you, but it is also pretty standard practice to separate the big ones first and the cubesats last so I am a bit surprised about
the late sep of ETRSS-1.

Do you have any idea about the size of the NUDT satellites? In the past they have launched everything from femtosat scale
to 100 kg class. I am guessing these two are more likely the latter, but they could be maybe 6U or 12U cubesats.

The satellites Yuheng and Shuntian were built by Shanghai ASES Spaceflight Technology but used by NUDT for intersatellite communication experiments. According to the ASES web page the satellites are based on companies Star Light SL-B platform. for which a total weight of 20-40 kg is given. NUDT named the mission of both satellites Gemini-1 (双子座).

According to http://www.smartsatellite.com/details?article_id=74 (http://www.smartsatellite.com/details?article_id=74) commercial sales of imagery from ETRSS-1 has begun. So it seems to be alive. Even if we (USSPACECOM) still dont't know which object from 2019-093 is representing ETRSS-1...
