Does anyone know anything about 56994 - 2023-084BW? It seems to be nonexistent in the recent celestrak listings. Can someone assign 56231 (BQ) to ROM-2 instead? It is pretty close to MRC-100 and pretty close to URESAT-1, so maybe it is ROM-2(?)

Dear All,
We are still not getting signal from ISTANBUL;s main beacon on 400 MHz, most probably we might have an issue with antenna deployment or the RTX module on OBC (OBS itself is alive).
As an emergency mode, after not being commanded from ground station, the satellite get into emergency beacon mode and transmitting TINY Beacon messages using its all transmitters, where the satellite has a 868 MHz LORAWAN beacon transmitter.
According to LORAWAN network we are getting signals from the satellite for the last 2 months on 868 MHz LORAWAN, but still no sign on 400 MHz.
We did an analysis on LORAWAN receptions from different LORAWAN gateways and we pretty sure ISTANBUL is Object BP.
I am attaching the analysis of last week to show how we came to conclusion that ISTANBUL is Object B.
I will be happy to hear your comments on this analysis, and also I would like to know what should be the next step to IDENTIFY and CLASIFY ISTANBUL satellite as Object BP on database/catalog.
Thanks

Hello Baris,
Could you share some additional details, such as the frequency? Is it on 868.1 or 867.5? As well as Spreading Factor, Coding Rate, and Bandwidth?

Sorry for late answer,
frequency is 867.9 and SF9
Looks like we have had some success with reception, thanks to K4KDR for the help!

56954 might have been identified.
which only had one match , shift D’d to the best center of the signal, leads to :
Let’s check if another one matches too.
According to space-track.org is HOTSAT-1. Which by the way seems to have some issues.
That’s sad … Arrange a pickup with a space shuttle…

Wondering if any of the missions was to separate in two parts, it needs some checking.

It’s not matching any of my unid’d 2265 MHz obs 
Might have an ID on 56988 AYRIS-1

Good evening @ea4gqs
I am going over my STRF observations (27-01-2027 01:40:00) and found an unknown signal that was received earlier.
When looking at the Doppler curve it was matching URESAT-1.
Until recent it wasn’t possible to receive signals from this satellite with a modest setup.
So the question is, has something changed,
The satellite was passing at Azimuth 283 and an Elevation of max 38 degrees so not optimal.
I will add some SatNOGS observation to see if we now can indeed receive URESAT-1.

Hi Jan,
This is really awesome. It seems the antenna has finally deployed.
We are going to send commands this night to try to activate the transponder and the amplifier.
We keep you all posted.
Thanks a lot for this information.
