I'd thought that AO-73 had been confirmed as object 66B. has this been refined? I guess I need to update my settings in SATpc

Hi Mike,
Thanks for the confirmation of the 'tbc's.
This picture shows the measured doppler curve of an overhead evening pass of OSCAR 73, plotted against the calculated curves for objects 39444 and 39445. These objects were about 11 s apart (i.e. about 82 km).
https://thumb5.wuala.com/previewImage/SharedInfo/Space/AO73_20131216.jpg/?ke y=IZKufoz9U1Uo
Note the temperature related frequency drift on the beacon transmitter, which causes frequency deviations when using automatic doppler correction. To be able to create useful doppler curves it would help if all Cubesats would transmit a *continuous* carrier signal on a *constant* frequency... ;-)
Still a lot of IDs are unknown. Of all the objects from the Minotaur launch, only three are officially identified:
39380 2013-064A STPSat 3 39388 2013-064J SENSE SV1 39392 2013-064N SENSE SV2
It is suggested that Cape 2 is object 39382 (2013-064C) and that KySat 2 is object 39383 (2013-064D). These are to be confirmed.

Just made a deep analysis with the FunCube TLE (Object AE vs. AF). The pass was not very high but every seconds I switched between the TLE AE and
AF.
You can see a slightly differnce (only a few Hz) at TCA what leads me to say
- your're right. FUNCube-1 seems indeed to be Object AE.

All,
Further doppler measurements show that TshepisoSat (aka ZACube 1) is object 39417 (2013-066B) and AMSAT-OSCAR 73 (aka FUNCube 1) is object 39444 (2013-066AE). Therefore HiNCube must be object 39445 (2013-066AF).
It is not easy to get a good doppler curve with many Cubesats because of the limited transmissions and because of the frequency drift of their beacon transmitters.
These object IDs from the Dnepr launch seem to be correct, although some still need to be confirmed (tbc):
39416 2013-066A Aprizesat 7 39417 2013-066B TshepisoSat 39418 2013-066C Skysat 1 39419 2013-066D Dubaisat 2 39421 2013-066F Unisat 5 39422 2013-066G STSat 3 39423 2013-066H WNISat 1 39425 2013-066K Aprizesat 8 39427 2013-066M Triton 1 39428 2013-066N Delfi-n3Xt 39429 2013-066P Dove 3 39430 2013-066Q GomX 1 39431 2013-066R BRITE-PL 39432 2013-066S HumSat D (tbc) 39436 2013-066W Eagle 2 ($50Sat) (tbc) 39438 2013-066Y Velox PII (tbc) 39439 2013-066Z First-MOVE (tbc) 39440 2013-066AA CubeBug 2 (tbc) 39444 2013-066AE AMSAT-OSCAR 73 39445 2013-066AF HiNCube 39446 2013-066AG UWE 3 (tbc)

Still no IDs are available for the satellites launched from the ISS (except TechEdSat 3P) and the Minotaur.
Several IDs have been published for the objects from the Dnepr launch but many need to be confirmed. Still not all TLEs are released.
AMSAT-OSCAR 73, ZACube 1 and HiNCube were launched from the same ISIPOD. As they initially were close together, the JSpOC decided to release only one TLE set for this cluster under object number 39417 (2013-066B). Now the distances between these satellites are slowly increasing. So the question is which satellite is object 39417. Detailed doppler measurements show that ZACube 1 is now about 25 s early compared to the TLE for object 39417, while OSCAR 73 is about 11 s early. This seems to indicate that object 39417 is actually HiNCube. Hopefully TLEs for OSCAR 73 and ZACube 1 will be published soon.

Hi all,
The story so far!
The first object number that was issued for the contents of ISIPOD-1 - ie HinCube, FUNcube-1 and ZAcube was 2013-066B
Some days later, 2 new objects were identified -2013-66AE and 2013-066AF.
Generally we thought that the best fit for FUNcube-1 was object 2013-066AF but more recent evaluations by our expert trackers now shows that FUNcube-1 is most probably 2103-066AE.
They are still only about 100km apart after almost a month in orbit. So we have been correct to hang back a bit before making any claims!
The FUNcube team will monitor results for just a little longer before doing so.
thanks
Graham G3VZV
