This is the first high spectral resolution satellite in the Gaofen series.
-
Launch schedule for September 2017.
-
Vacuum and thermal tests successfully completed.
-
Which rocket is this launching on? This article says CZ-2D from Jiuquan, but the Chinese Launch Schedule thread has it on a CZ-4B from Taiyuan.
-
Not sure if this is what you are referring to, but this link:
https://www.chinaspaceflight.com/China-Launch-Schedule.html
says CZ-4B from Taiyuan.

.03cm ? I don't think so. .03M (30cm)--maybe..

Spectral resolution is not the same as spatial resolution. Spatial resolution is in the 20-40m range.

Looks like this launch still schedule for later 2017
-
The target orbit is 705km SSO, it should be carried by CZ4C
-
According to a posto on the 9ifly Chinese space forum, the launch of Gaofen-5 will take place on May 2, delayed from April.

China to launch new Earth observation satellite in May
-
No NOTAMS so far, but all rumors still points to launch date on May 2.
Given that this is local time, it could even be late today GMT- e.g. this Chinese paper (http://shht.ijournal.cn/ch/reader/view_abstract.aspx?file_no=201703001&flag=1) gives GF-5's orbit as 705 km SSO with LTAN of 13:30, implying the daily launch window at around 18:00 UTC - which is early next day in China. On the other hand WMO list (https://www.wmo-sat.info/oscar/satellites/view/609) an orbit with LTDN 13:30 - which leads to the daily launch time at ~06:00 UTC.

Latest post on the same forum points to launch a few days later. (well, at least earlier official news puts the launch in "early May" so....)

Are there any tracking ships supporting this launch?

Do we have any updates on the expected Launch time for Gaofen-5 on May 2nd ?????

Yes, Yuan Wang 3 is tracked to be in the Indian Ocean (left Jakarta on April 30) and should be on station in a few days time.
New reports put the new date on May 7 or May 9.

According to the Chinese 9ifly space forum, launcher serial number is Y20.

I'll be dead asleep at T-0 so I will be grateful if someone takes over the watch for any news from the state media. :P

Here's a 2016 presentation on the satellite - quite a combination of atmospheric and trace gas/greenhouse gas observation instruments: http://ceos.org/document_management/Virtual_Constellations/ACC/Meetings/AC-VC-12/Day%201/5.%20Linagfu%20Chen%20-%20Gaofeng-5%201013.pdf (http://ceos.org/document_management/Virtual_Constellations/ACC/Meetings/AC-VC-12/Day%201/5.%20Linagfu%20Chen%20-%20Gaofeng-5%201013.pdf)

Launch time has passed. Waiting for news from Taiyuan...
-
Still no news about the launch. I'll assume its normal because of the late hour in China.
-
18:28 apparently, and all looks good. Waiting for something more official, however.

BEIJING, March 21 (Xinhua) -- Two Chinese Earth observation satellites, the Gaofen-5 and Gaofen-6, were officially put into service on Thursday after completing in-orbit tests.
During the tests, the two satellites provided precise data on environmental monitoring, natural resources and natural disasters, according to China's State Administration of Science, Technology and Industry for National Defense (SASTIND) and China's National Space Administration (CNSA).

Launched on May 9, 2018, Gaofen-5 is the first China-developed satellite that can monitor air pollution. It can dynamically reflect the state of air pollution in China through the monitoring of air pollutants, greenhouse gases and aerosols.
...
The Gaofen-5 and Gaofen-6 will form a constellation with other Gaofen satellites in orbit.
Gaofen means "high resolution" in Chinese. Since the Gaofen project began in 2010, China has had an increasingly clearer view of the planet...
