DNEPR Launch a succes

The DNEPR launch was/is a success.

The launch as you can see in this Youtube movie below was a success, the launch took place at 07:10 UTC from the Dombarovskiy facility.

Just a couple of minutes after the launch signals where received from FUNcube-1, these came from Amateur Radio Stations in South Africa and they filled the FUNcube-1 data warehouse for the first time.

My first pass was at 08:46 UTC and I had to make up my mind on with cubesats to track. I finally choose for monitor and record a frequency span between 437.350 – 437.540. In the middle of this span would CubeBUG-2 transmit its data. In meantime listen to Delfi-n3Xt at 145.870. When the pass started it was a overwhelming. Delfi-n3Xt pass coming via the VHF Icom 910H and the 192khz span of the FUNcube Dongle Pro+ showed a lot of signals being received. I wasn’t able to decode any 2400 baud BPSK signal from Delfi-n3Xt but after the pass when I analysed the IQ file that was recorded with SDR# I could decode signals from ZAcube-1, UWE-3 and CubeBUG-2.

The following frames are decoded from a recorded SDR IQ file, therefor the timestamps are of.

ZAcube-1 1k2 decode:

In a later pass also an APRS message from CubeBUG-2:

So far so good, I have 2Gb of IQ data that can be analyzed. This is what I can tell so far, the launch is a success and there are some teams that are still searching for there satellites. Good luck all, I’ll point my antenna’s to the sky when I am able to.

After analyzing the IQ files I also saw the data from Humsat-D, very strong 1200 baud GMSK data and Morse code, modulation type FM. Very difficult to decode the CW data. It is time I learned CW because the Computer isn’t able to decode the data.
