The NOTAM for CZ-3B from Xichang, maybe with CZ-1, the CZ-2C for Jili Group 03 might be on September 25.

Please amend the title as M26 and M28 have been launched on Dec 26.

The December launch was M26/M28 according to https://www.csno-tarc.cn/en/system/constellation .
As of time, we'll see in two weeks.

JSR lists the 26 December 2023 satellites as Beidou DW 57 (Beidou-3 M25?) and Beidou DW 58 (Beidou-3 M26?). The Chinese "Test and Assessment Research Center of China Satellite Navigation Office" web site looks pretty official, so I think M26 and M28 are correct for the last launch. This launch might be M25 and M27.

I've corrected GCAT to show M26 and M28 for the last launch.

Launch success has been officially confirmed, with CAS Shanghai confirmed as the manufacturer for these 2 satellites. Some official reports also indicate them to be the final satellites of the 3rd generation Beidou satellites.
