After the last 2 passes over Adelaide, I have the following doppler fits:
Name Frequency Best TLE Residual
CSIM-FD 437.250 43758 164 Hz
ESEO 145.895 43792 59 Hz
FOX-1C 145.920 43770 56 Hz
ITASAT-1 145.860 43786 18 Hz
JY1-SAT 145.840 43788 46 Hz
MinXSS-2 437.250 43793 67 Hz
MOVE-II 145.950 43780 19 Hz
PW-SAT2 435.275 43780 258 Hz (No good fits, this is the closest within the SSO-A group)
RANGE-A 437.150 43798 107 Hz
SNUGLITE 437.275 43784 114 Hz
SNUSAT-2 437.625 43782 55 Hz
SUOMI-100 437.775 43788 437 Hz (No good fits, this is the closest within the SSO-A group)
Note that there is some overlap on the above fits. This should get better as more TLEs become available.
Cees and I have also discovered the following ‘mystery sats’, part of the SSO-A group:
Mystery-1 436.730 43768 21 Hz (4800 baud GMSK, NanoCom AX100 ASM+Golay mode, with CSP packets)
Mystery-2 436.500 43788 203 Hz (Possibly CW-over-FM)
Mystery-3 435.500 43783 110 Hz (Possibly 4800 baud GMSK)
I would suggest that entries be created in the DB with the mystery sat details, so further observations and hopefully decodes can be gathered. This may help identify these objects.
I’ll continue to monitor the above fits as more TLEs become available for this launch.
