Yaogan 31 Group 03 - CZ-4C - Jiuquan - February 24, 2021 (02:22 UTC)

[Satori]

China will launch the Yaogan 31 Group 03 triplet around February 22, 2021, using the CZ-4C (Y32) from the Jiuquan satellite Launch Center.

Some rumors that this launch will take place tomorrow. No NOTAMs for the drop zones at this time (?).

Same zone as YG-31-02.

If launched at 09:52 Beijing time (01:52 UTC), the YG-31 03 triplet plane would be 48° E of the 02 triplet -- the same separation as 02 from 01.
Unfortunately the time is not inside the NOTAM window.

Interesting design with the mission patch from the mission along with the previous one. This makes me think that we'll see a third trio launch sometime soon.

JIUQUAN, Feb. 24 (Xinhua) -- The third group of China's Yaogan-31 remote sensing satellites were sent into space from the Jiuquan Satellite Launch Center in northwest China at 10:22 a.m. (Beijing Time) Wednesday.

The satellites were carried by a Long March-4C rocket. It was the 361st flight mission of the Long March carrier rocket series, the launch center said.

Having entered their planned orbits, the satellites will be used for electromagnetic environment surveys and other related technology tests.

China launched the first and second Yaogan-31 satellite groups on April 10, 2018 and Jan. 29 this year, respectively.

So YG 31-02 and -03 groups went into new planes, and from the looks of it we should expect at least one more group to have an almost-regular plane spacing (and revisit).

I was just guessing on the fly without looking while in a meeting.
