New Satellites: Plan for SSO-A SmallSat Express Launch on December 3rd

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.
