This weekend we did some website maintenance, we created a new db server that can handle more load and enable IPv6. I welcome the new IPv6 visitors and hope you enjoy the information that can be found at this website.

The below image is a Orbitron view screen overview with satellites that I am trying the track and decode at the moment. After the last launches, there are a lot of them.
It is an overview at 19-01-2014 09:32 UTC.
Delfi-n3XT Telemetry
Delfi-n3XT Telemetry 11-01-2014 10:09 UTC
Decoded with Maspro UHF yagi, SSB preamp, FUNcube Dongle Pro+, SDR# and DUDE Delfispace ground station telemetry decoder. After that the raw packet data was used as input for one of the nice decoder software packages from Mike DK3WN.
The latest versions of the software packages from Mike come with a save function that makes a transparent screenshot from the software output. A very nice new feature. Thanks Mike.

Finally I was able to decode some Delfi-n3XT data. I used a FUNcube Dongle Pro+, SDR# in USB mode with a bandwidth of 3800 Hz and the DUDe software provided by the Delfi ground station team. A total of 251 packets received and forwarded to the ground station server.
Below an image from the received spectrum:

Triton-1 Telemetry 04-01-2014
Triton-1 Telemetry 04-01-2014 11:56 UTC
Decode: FUNcube Dongle Pro+, MixW (Packet VHF 1200 baud (satellites PSK))
It is tough to decode Triton-1 because the frequency is drifting a lot. This decode was done at 145.823 MHz USB.
