Today Test Carrier, the frequencies: 12111 V,12677 H,12149 V,12188 V, 12265 V,12560 H.

12677 H-test carrier, again

12521 H test carrier, again

12110 V-test carrier. Idem atm

 

[satesco]

12111 V-again today tests on carriers from previous days

 

[Marcus_21]

For several hours now, 16 transponders have been switched on, without modulation... two of which have a bandwidth of 72MHz (11976 V and 12130 V).

do they have a planned order of transmissions,or are they trying out the machine before using it?

 

[hvdh]

I wonder why the satellite started to drift to the East.

I thought it was a lnb error. Even now, I'm unsure, but I'd better post my spectrum to check if it's an error or a more elaborate test.

What would we do without you and @hvdh when new satellites are being tested?

 

[hvdh]

Hi Satesco, my spectrum looks similar, but with weaker peaks. No locks.
@Marcus_21 analyses the in-orbit testing so thoroughly, I hardly bother any more!

The STK (Systems Tool Kit) software that I use to produce these historical satellite position graphs is many years old, with a free license that should continue to work as long as this PC it is installed on doesn't die!
Unfortunately, nowadays free licenses do not exist any more, and they are unaffordable.

As alternative, the Celestrak site can also show historical TLE-based longitude charts, but it's rudimentary, and after asking him it can not be improved.
I'd like to hear if any other software or site exists, that can load historical TLE's, and create graphics from them.

For those interested in position 50.0E and did not test the signal on Turksat 6A, I am posting the spectrum on Turksat 4B with active transponders. It may help.

 

[Marcus_21]

From the tests I have observed so far, these are the frequencies tested:



Let's see in the next few days if new frequencies will be tested, or these are all the frequencies available.

 

[satesco]

I think 11704 V would be a beacon(?). Looks like QAM.
I also found 12547 H and 12577 H, but I don't know if they are for testing or what.

 

[Marcus_21]

On the frequency 11704 V, there is no beacon.. there is a strong signal on 11705 V from the nearby Quantum.


Now the two telemetries (11697.50 and 10700.50) are in circular polarity RHCP. During the period that they were in linear polarity there was an unmodulated signal, similar to a beacon on the frequency 11451 V... let's see when it will be operational at 42°E it will be turned on, in order to confirm if it is actually a beacon.


I also note that on the frequencies 10954.50 H and 10955.6 H, there is a telemetry of the turksat 4B and one of the 6A, but they are emitted by a transponder of the 4B... I do not know the reason why they are sent in uplink to this transponder.

 

[satesco]

Testing on Turksat 6A is not finished yet.
Here's one at 12034 V at this time and day.

 

[hvdh]

Turksat 6A left 50°E, now near 48°E and should arrive at 42°E around Dec. 28.
