The debris zone notice confirmed the launchcode 07-80
I'm confused by the nomenclature here. Beidou-3 M1-S and M2-S were launched in Jul 2015. Now these are Beidou-3 M1 and M2? What was the significance of the -S on the previous Beidou-3 launches (and do we have a Chinese source for the M1 and M2 designations?)

(1) Some earlier sources indicates that -S stands for
shiyan (Experimental in Chinese)
(2) Haven't seen an official name for these two yet - in fact I wish the Chinese can stick with a consistent naming conventions for their BDS satellites! I mean, you have GPS SVN XX, GLONASS-M #7XX and Galileo GSAT0XXX, but for BeiDou the only "reliable" way to call the individual satellites is by calling them the "
nth satellite".

Also a small rant - apparently the only one-stop place I have seen of getting the status and almanac of the BeiDou satellites is from.....
the official GLONASS website! I am also waiting for public BeiDou status messages to appear (I mean, I'm about to get a new smart phone tomorrow that can use all "Big 4" navsat constellations, yet it's harder to get info on 1 of these 4).
Launch time: 19:45:04.244(UTC+8)
You can see that the two satellites are marked as "MEO-1" & "MEO-2" on the display screen of the LCC.
