New EntrySat Cubesat

If your are interesting, the kaitai file (*.ksy) for Entrysat is avaliable on : https://code.electrolab.fr/xtof/telemetrydescription/tree/master/EntrySat

It’s used to implement an EntrySat decoder in java. [ java source code for telemetry decoding] (https://code.electrolab.fr/xtof/josast/tree/master/ModuleEntrySatTelemetry)

Hah, great, I also generated one!
Let me compare :wink:

Yeah, well, that looks good! Proud to see this progress! My approach looks very similar, so maybe we could synchronize them to have a decoder for the data warehouse!

Compare: https://gitlab.com/librespacefoundation/satnogs/satnogs-decoders/merge_requests/92

Be careful on using the bit types in kaitai - there is an issue with MSBit and LSBit. So please double check the results. If you run into trouble, I can give you some hints how to ship around this.

Any news in the date?

Last schedule : first week of July … 73, Nicolas

If you read it on the webpage the asterisk seems to be translated into some markdown code or similar - so the calculation gets unreadable :wink:

Hello fredy,
The deployement of EntrySat is scheduled tomorrow July 3th at 15h00 UTC. Is it possible to activate it in the system using the same TLE than ISS ???

Thanks for notifying me, I’m going to add ISS TLE in a couple of hours and schedule observations for it.

Now EntrySat follows ISS TLE until we get any extra norad id. Observations are scheduled on several stations!

Deployement is delayed to July 3th, 16h25 UTC (Nanoracks info), so EntrySat should start to emit 17h UTC.

This is the first scheduled observation after EntrySat starting transmitting. The first results should be in at ~17:40 UTC.

This should be EntrySat! https://network.satnogs.org/observations/792209/

@F5MDY can you confirm it?

Yes it is !!! We are very happy and appeased ! But we can’t decode the beacon because the audio file is compressed and the resultant bandwidth is too narrow to demodulate …

From some recent observations with telemetry frames decoded I found that there are some more frametypes EntrySat transmits. Do you have some more documentation about them or should we just skip them inside the kaitai struct?

We would need to add some simple “switches” as protection against misinterpretations of the frame contents.

Congrats to a successfull launch!

Dear Patrick

You need to filter on SSID : value 6 for the telemetry frame to decode. I use this filter in the Entrysat demodulator to display data. But all telemetry frame are sent to Entrysat Database and Satnogs Database.

I work with the Entrysat Team for other type of telemetry.

Regards
