After some analysis by @PE0SAT we have that the modulation is GOMspace AX.100 Mode 5 FKS1k2
and from one of the demodulated frames we have:
47414c41535349412d3200a5a5a5a5a5a5a5a5a5051d0512051e205d002d008f00110021001700000000003e0000004a000000000001000100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000dff0008b6d10505000000000000000000000000000000000000000100080007000600060004000507030200000071007302000100000001b9fcd01c0239fd2f6b020075007a0007000001000000000000000000000000fc19fc19fc19fc19827f38a7
Where the first hex digits are translated to GALASSIA-2. So, we can confirm that this is the satellite.
