It's noteworthy that this Long March 2D is equipped with grid fins to add some control of the landing of the first stage.

“郑州航空港号”卫星发射成功
Quote
"Zhengzhou Airport" satellite launched successfully

From today, in the night sky, there will be a star named "Zhengzhou Airport" - at 11:06 Beijing time on May 20, 2024, the "Zhengzhou Airport" satellite was launched from the Taiyuan Satellite Launch Center on the Long March 2D carrier rocket. The satellite successfully entered the predetermined orbit and the launch mission was a complete success.

The "Zhengzhou Airport" satellite is a new generation of remote sensing Internet satellite approved by the National Development and Reform Commission. It is an important carrier for the cooperation between Zhengzhou Airport Economic Comprehensive Experimental Zone and the 21st Century Space Technology Application Co., Ltd. (referred to as "Century Space") to carry out space information services. The satellite has the characteristics of high agility, high stability and high precision. It can obtain ground pixel resolution of 0.5 meters for full color and 2 meters for multi-spectral, which is better than 12 kilometers wide.

The "Zhengzhou Airport" satellite is equipped with Century Space's onboard intelligent monitoring and on-orbit processing technology. Together with the ground measurement and control receiving station network, Internet cloud service center, user application terminals, etc., it forms an integrated "satellite-ground-cloud-end" system that can achieve rapid coverage of large areas, has on-orbit intelligent image processing and information interpretation and analysis capabilities, and supports on-orbit extended processing functions.
The one of payloads named Zhengzhou Hangkonggang (郑州航空港号).

Beijing-3B has been renamed to Beijing-3N
So payloads as below:
Beijing-3C 01(北京三号01)
Beijing-3C 02(北京三号02)
Beijing-3C 03/Nanning-2(北京三号03/南宁二号)
Beijing-3C 04/Zhengzhou Hangkonggang(北京三号04/郑州航天港号)
Where did you know Beijing-3B to Beijing-3N?

source e.g.: https://eos.com/blog/21at-asia-and-spacewill-enhance-eosda-landviewer/


The 21AT Asia satellites, including Beijing-3A and Beijing-3N (formerly known as Beijing-3B), provide pansharpened images with resolutions of 50 cm and 30 cm, respectively. Native resolutions of multispectral bands are 2 m for Beijing-3A and 1.20 m for Beijing-3N. The satellites boast a revisit rate of approximately 4 to 5 days and can cover areas from 25 km², offering users up-to-date and detailed imagery.

I think they are wrong, and the BJ-3N designation refers in fact to Pleiades Neo.
This message reflects my personal opinion based on open sources of information.

Yes, maybe. There seems to be some kind of strange relationship between the two technically similar programs. But https://www.satimagingcorp.com/ and others are selling Pleiades Neo AND Beijing-3 images separated from each other. Maybe in this case the N stands for Nanning because of BJ3B = Nanning-1? On the other hand - this company (http://www.kosmos-image.com/?m=wap&a=show&catid=73&typeid=4&id=5810) is talking about the the Pléiades-Neo 3 & 4 as BJ3N1 and BJ3N2, expecting the launch of BJ3N3 & 4 in 2022 (probably the ill fated Pléiades-Neo 5 & 6).
Question: Would it make sense to view BJ3N1, BJ3N2 (Pléiades) and the lone BJ3B aka BJ3N as ONE constellation? Orbit-wise? BJ3B/BJ3N as a stopgap measure?
