13.25°E H2Sat (Heinrich Hertz)

<Edit> Was at 0.5E, moved to 13.25E November 2024

Has anyone seen anything from this satellite, apart from its Ku beacon?

ITU had the following bands listed:

2283.5-2288.5MHz (TT&C)

10950-11700MHz

19.7-20.2GHz

20.2-21.2GHz

Hi s-band

My circular scan shows a peak at 20200 on 1.8m.

Thanks, qwer, I had another look on Ku and can just see the a BPSK that flips in the demod creating an X.

I also noticed that there's a carrier on 10951MHz which appears to be circular polarised.

Just a try here on 2.2m... on 10951 and 10953...

I can see a "butterfly" (joke)

Wenn man sich Wikipedia ansieht, könnte das K-band erfolgversprechender sein, als das Ku-Band.

If you look at Wikipedia, the K-band might be more promising than the Ku-band.

I found this pre-launch document:

It looks like you are correct femi

• 7 channels with 36 MHz bandwidth each at Ka-band (= appr. 7 x 50 Mbit/s = 350 Mbit/s)

• 1 channel with up to 450 MHz bandwidth at Ka-band (= appr. 1 x 625 Mbit/s)

• [1 ISL (Intersatellite Link) with 36 MHz bandwidth at Ka-band (= appr. 1 x 50 Mbit/s)]

• 1 channel with 45 MHz bandwidth at Ku-band (= appr. 1 x 62 Mbit/s)

The coverage map shows a different orbital position but 2 of the beams are very tight on north and south Germany. There probably will not be anything de-codable.

Now in circular range from Ka Band B... peak is probably on: 20198

Thanks to hvdh for the information, H2Sat has moved to 13.25E. I can't see anything from it on Ku now as it is too close to 13E and its beacon frequency has a DVB signal on it.
