ESA feed detail posted at https://www.esa.int/ESA_Multimedia/T...pe_live_launch

Satellite Parameters:

Eutelsat 7B @ 7degE
Transponder F6 Channel 1D9 (9 MHz)
D/link freq: 10978.0 MHz Polarisation X/horizontal
Signal: MPEG4/H264, 4:2:0, SR: 7200 Ms/s FEC: 3/4 DR:15.678 Mbps
Modulation: DVBS2/8PSK, Pilot: On, Roll off: 0.25 Clear
Audio 1: English mono
Audio 2: Spanish mono
Audio 3: French translation mono
Audio 4: Intl mono

Band/TP details there are contradictory: 7.0E transponder F6 is 72MHz centred on 12708.33MHz Vertical, whereas the frequency posted is Horizontal Lo band (7E band F1 9MHz Channel C)... go figure.

Guess we'll know tomorrow when the feed pops up on 7E what info is correct, or if there are two TPs for this critical launch.

Edited to add: ESA feed's ident (provider) will likely be: CSG Kourou (Arianespace)

Not just on regular NASA TV regular broadcast channel. There were three feeds on 7E: ESA as per their listing, and posted by Ratzvan above, plus https://www.sat-universe.com/showpos...postcount=4901, plus live on EBU2 @ 7E 11050H 4937.

There must have been other feeds too, unreported here, as whilst 7E 10978H 7200 was showing an EBU xmas reel / dancing penguins soon after the feed came up, there was one instance of a brief cut to endarkened launch pad.
