Has the launch code been confirmed, please?   I have not seen any of the launch control room shots for this launch, and they usually show the code.

LKW-3 orbit's RAAN is 44 degrees greater than the one for LKW-1 and LKW-2

No confirmation but as LKW-2 launch code was confirmed as "01-85" (see below), we would expect "01-86" for this one

I *never* assume anything with the Chinese, no matter how reasonable it might be!!! :)

The lack of official information suggests a failure to reach the desired orbit.

LKW-3's orbit is nominal minus the RAAN and inclination in relation to the first two LKW's.

Catalogued as 2017-084A/43080.   The orbit is coplanar with the first satellite in the series.
Confirmed!

LKW-2's orbit at epoch 10:04Z: 491 x 502 km x 97.46  RAAN: 70.60     2017-084A/43080
LKW-1's orbit at epoch 04:52Z: 488 x 504 km x 97.46  RAAN: 69.72     2017-077A/43034

Satellite longitude difference: 180
LTDN: 10:30 am
A first object has been cataloged by USSTRATCOM:

2018-006A/43146 in 488 x 503 km x 97.34
LKW-3 orbit's RAAN is 44 degrees greater than the one for LKW-1 and LKW-2

Sorry, should have said "The lack of official information suggests some kind of failure"

Or the lack of information could be because the Chinese have said all that they want for the first two satellites and they don't want to repeat it.

Can't see any problem in this. First pair of LKWs has local descent node crossing at 10:30 and the second pair at 13:30. Very reasonable.

Ummm... it's occured to me that LKW-1 and -2 are working at exactly the same orbital height as the three Tianhui mapping satellites. A coincidence or not?
