Can someone please tell me what is happening with ESEO, has it been tested and is it ready for operation yet?
Thanks Ross ZL1WN
Hello Ross,
Can someone please tell me what is happening with ESEO, has it been tested and is it ready for operation yet?
See below for the ESEO excerpt provided by the FUNcube operations team in the AMSAT News Service bulletins. The full text of the bulletin is posted at: http://amsat.org/pipermail/ans/2018/001076.html
ESEO (FUNcube 4) ---------------- Signals and telemetry continue to be received from ESEO from the main platform transmitter on 437.00 MHz. The are bursts of 9k6 data transmitted every one minute. Full details of these trans- missions, including the telemetry equations, can now be found at https://www.esa.int/Education/ESEO. Daniel Estévez, EA4GPZ, com- mented that the beacon at 437.000 MHz it is not standard FSK AX.25, and it cannot be decoded with direwolf, UZ7HO or similar.
The AMSAT payload transmitter on 145.895MHz has not yet been act- ivated and it seems likely to be sometime before this occurs.
Uplink: 1263.500 MHz FM voice with 67Hz CTCSS tone Downlink: 145.895 MHz FM voice and telemetry Telemetry: 145.875 MHz Use ESEO Dashboard from AMSAT-UK https://download.funcube.org.uk/ESEO_Dashboard_v1177.msi

Hi Ross,
I haven't heard much official information about the status of the satellite and the progress of the mission. I think the FUNcube payload is not active yet.
Now that we have a working decoder for ESEO (https://destevez.net/2018/12/decoding-eseo/), we can watch the telemetry to investigate about the satellite status.
Mike DK3WN captured some telemetry packets a couple of days ago: http://www.dk3wn.info/p/?p=91603
A telemetry parser for these is not ready yet, but the documentation is available here: https://www.esa.int/Education/ESEO/Be_the_first_to_catch_a_signal_from_ESEO
From a quick look by hand at the packets, it seems the spacecraft is in
safe mode and several systems are powered down.
PS: We still have to figure out some small details / check our understanding about the telemetry format, so it would be good if you can send us some more telemetry packets in hex as Mike did, so that we can check our ideas.

Dani EA4GPZ.
All, ... telemetry parser is in progress - but it's a very complex telemetry - so give me some time, please ;-)
73 Mike

Thanks Mike, judging by the look of that signal, I can certainly understand it will be difficult to decode. Ross ZL1WN
