Triton-1 update #4 23 November 2013 08:30UTC - new Triton1 TLE available
Hi all,
New TLE's for the DNEPR launch have been issued, we believe that Triton-1 is object M.
2013-066M 1 39427U 13066M 13326.98436826 -.00002391 00000-0 -39688-3 0 10 2 39427 97.7901 39.5474 0120424 185.3601 174.6374 14.64539763 201
Meanwhile, Triton-1 is still in nominal mode, transmitting AX.25 BPSK on 145.822MHz. Reception reports, especially in case the satellite is in safe mode (transmitting the safe mode CW beacon) are welcome!

All,
An overview of the presently known IDs for the satellites that have been launched recently.
ISS JSSOD Cubesat launches 2013-11-19 12:18 UTC 39412 1998-067DA Pico Dragon ? 39413 1998-067DB ArduSat 1 ? 39414 1998-067DC ArduSat X ? To be confirmed when the objects have more separation. 2013-11-20 07:58 UTC 39415 1998-067DD TechEdSat 3P
Minotaur 1, Wallops Flight Facility 2013-11-20 01:15 UTC ORS3 & ELaNa 4: 29 satellites So far only 4 TLEs published. No IDs yet but probably: 39380 2013-064A STPSat 3
Dnepr, Yasny 2013-11-21 07:10:11 UTC 32 satellites 19 TLEs published 39417 2013-066B FUNcube 1 39427 2013-066M Triton 1 39428 2013-066N Delfi-n3Xt
Note that all designations may change later on.

All,
An update on the satellite IDs.
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 Nico,
Thanks for the update, this would explain why the doppler correction for AO-73 isn't working with the current object-id.

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)

Thanks Nico, PA0DLO for pointing me in the rigth direction. I agree with you the TLE for the cubesats:

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.

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...
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.

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 Nico,
Thanks. I use #39388 (Object J) for KySat-2 and 393882 (Object C) for CAPE-2.

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)

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.
