Title: Yaogan 31 Group 03 - CZ-4C - Jiuquan - February 24, 2021 (02:22 UTC)
Post by: Satori on 02/19/2021 01:31 pm: China will launch the Yaogan 31 Group 03 triplet around February 22, 2021, using the CZ-4C (Y32) from the Jiuquan satellite Launch Center.

Post by: Satori on 02/21/2021 11:39 am: Some rumors that this launch will take place tomorrow. No NOTAMs for the drop zones at this time (?).

Post by: Liss on 02/23/2021 01:35 pm: 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.

Post by: Josh_from_Canada on 02/24/2021 03:26 am: 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.

Y28, 29, 30, 34 and 36, for example, have not yet been used.

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.

Post by: gosnold on 02/24/2021 07:00 pm: 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.

patches show three planes of three sats each.

Well, how would I change this numbering if I were at The Mountain?
Of course I would name E as A and vice versa.
But they have switched A and B instead, so A, C, and E are maneuvering now. Much better!

We moved out of The Mountain in 2007. So it's more like the West Coast.
