Thanks @sv2hwm, are these going to be deployed from ISS or from a rocket launch.

By the way any help on adding these data in DB would be more than appreciated! For anyone who have the time to contribute on this task, here is the guide for adding new satellites and for adding new transmitters.

I’ll answer my own question
It is a rocketlab launch: Electron | Kakushin Rising (JAXA Rideshare) Mission

We have the precise launch datetime 2026-04-23 03:09 UTC

Also ARICA-2 team has shared TLE in amsatbb list:

ARICA-2
1 99999U 27001A   26113.16829861  .00000000  00000-0  00000-0 0  9999

Which becomes this TLE if we use the DB temporary NORAD ID:

ARICA-2
1 98329U 27001A   26113.16829861  .00000000  00000-0  00000-0 0  9995

I’ll take a look on the other satellites later today, any help by suggesting them in DB is more than welcome!

Launch was on time!

In total 1450 observations have been scheduled for the first 48h after deployment of the satellites. We have used the TLE sets of the previous post.

The difference in the number of scheduled observations is based to:

Frequency of transmission of the satellite
Orbit of the satellite/TLE set
Request by or communication with the satellite team
Spectrum misuse or violation of regulations

Temp NORAD ID	Satellite	Scheduled Observations
98329	ARICA-2	233
98325	OrigamiSat-2	170
98324	MAGNARO-II - Tigris	270
98323	MAGNARO-II - Piscis	230
98328	KOSEN-2R	191
98326	FSI-SAT2	186
98327	WASEDA-SAT-ZERO-II	170

From the first observations we have the two “MAGNARO-II”, ARICA-2, FSI-SAT(confirmed transmitting on that frequency) and WASEDA-SAT-ZERO-II received and alive!

Not many observations from OrigamiSat-2, there is a hint of transmission in one observation but not sure if it belongs to the satellite. No signal on KOSEN-2R frequency.

TLE are good for tracking but need some fixing, there will be updates later when we have more observations preformed.

K4KDR · April 23, 2026, 6:53am

Sounds like OrigamiSat-2 is alive also!
