RS-28
08:19 UTC strong data transmission on 435.266 MHz
10:03 UTC only short bursts on 435.441 MHz
… FM data signal of RS-28 (complete block 60 sec)
RS-28
18:25 UTC strong data signal on 435.441 MHz
RS-28
17:50 UTC data signal on 435.266 MHz
DOKA data
OBJECT E – RS-28 (?)
seems they have several frequencies …
18:15 UTC FM data signal on 435.441 MHz (FM)
19:55 UTC FM data signal on 435.266 MHz (FM)
tracked with OBJECT E -> perfect match
RS-28
18:54 UTC good match with TLE OBJECT E (NORAD 35869). Strong signals and much activity from groundstation
… CW beacon of RS-28
2 downlink frequencies: 435.365 MHz and 435.465 MHz
UHF spectrum 435.365 MHz with doppler correction (used TLE OBJECT E)
data transmission similiar to Yubileiny (RS-30) -> multiplex system
