SatNOGS Database entry for YOMOGI

It will be like SAKURA (its predecessor), however with a CW beacon more like the one from CosmoGirl-Sat (2 types with 5 bytes each).
And they are reusing the callsign JS1YMX from KASHIWA.

YOMOGI was brought up to the ISS together with LignoSat on 2024-11-05 by a Falcon 9.

It’s not for download, it’s just a presentation (紹介). Interesting anyway.

I’ve created a thread for the deployment, let’s keep this thread for details for the YOMOGI mission.

The dashboard is still under construction, but the decoder is already up and running.
So, feel free to upload received CW beacons using this instruction.

The data will be displayed on the dashboard once online.

Is there any publication of the conversion formula to decode the CW beacon?

I found this publication HERE, but we only have the beacon format

That is the only one I have seen, you could email Gardens citsatellitegardens@gmail.com

Try this:

There is already one CW beacon in the database:

0x9d is the battery voltage.
According to the conversion formula, this makes 4.05 V.

This is from the team’s web based decoder if that helps.

YOMOGI pass over Bali, OI71oi.
CW " si832d a583816000 "

Well, the YOMOGI made its first pass over Brazil today (2024-12-09) at 20:47UTC

I (PU4ELT) and PY4ZBZ received a transmission that was as follows: “A483802109”

With that, we have something strange about BAT_I, which according to the formula used in SAKURA would be this (HEX VALUE CONVERTED TO DEC 83=131):

In the online decoder we have this:

150mA :thinking:??

Sorry if I made any mistakes (I’m still dumb at this)

There are si only beacons and those with a data part.
The gap between two beacons is 85 seconds long.

Well, I got a reply by email and the calculations are indeed different from those used by SAKURA…

See the calculations used in the YOMOGI HERE
