SpaceX F9 Transporter-3 - 2022-01-13 15:25UTC

The passes are still low, however we have received probably 3 of the satellites:

SatNOGS Network - Observation 5292603 - visible and audible CW at ~340s and RTTY FSK at ~200s
SatNOGS Network - Observation 5292601 - very faint signal at ~350s


which is confirmed also by @EU1SAT:


Not sure 100% for this but the straight line follows the TLE and at the end another short line is visible at the left side.


Receiving packets from FOSSASAT-2E on TinyGS, they seem to be fine.



the document on below link says the frequency for Grizu 263-A is 435.675 and Bit Rate is 2.4k.
But on satnogs it seems as frequency is 437.190 and bitrate is 4.8k.

Frequency 435.675 MHz
Band Width 12.5 kHz
Bit Rate 2.4 kbps
Modulation Type FSK

Does anybody know which one is the right information?

Best Regards.

Any idea how old is this pdf? The frequency in DB is from the IARU Coordination IARU Sat Coordinator which the team should follow, so I expect this to be the right one.

GFSK transmitters have been added in DB for FOSSASAT-2 satellites.

From matrix chat, there is maybe a misconfiguration so we are going to add this transmitter to watch both frequencies to be sure that we receive it.


AOS 19:43 UTC
Frequency 435.675 MHz

First signal from Grizu-263A is confirmed! It seems correct frequency is 435.675Mhz.


Any reference? Links?

On a low (26°) elevation pass to my east (0204utc 14-Jan-2022), and then an even lower pass to my west (0341utc 14-Jan-2022), packets were seen consistent w/ Delfi-PQ. 1k2 FSK is difficult to decode under the best conditions, but unfortunately I was not able to do anything with these weak signals.

Does anyone know if Delfi-PQ beacons should transmit on a 1-minute interval? These packets were exactly 1-minute apart, so in addition to the freq. & doppler that would be helpful to keep Delfi-PQ as a possible source for these packets.




We have several recordings in Network too, what worries me is that it seems to not follow too good the TLE sets (the pre-launch ones) and are visible only above US. Let’s keep watching.

It looks like SATLLA-2A and -2B transmit another signal than LoRa too. Needs more investigation.

Also we haven’t demodulated any signal from Tevel-1 yet, maybe it is just a coincidence as all the other, seven, are transmitting in the same frequency and may not give a window to Tevel-1 to transmit.

BRO-5 is also alive and received.

Some updates for the UNICORN satellites:

SatNOGS DB is updated and UNICORN 2TA1 (TartanArtibeus-1) is now with alive status allowing scheduling in Network. All future observations for UNICORNS have been updated to follow the new transmitter updates, by the way this is done automatically with the code landed recently.

I’ve just asked for the interval to make sure.

Well, only took me an entire day to decode the strongest of those Delfi-PQ packets from the better of my two passes yesterday. But, glad to see that the satellite is alive!



the MDQSAT frequencies are:

436.8 and 437.2 MHZ LORA mode according ITU no IARU accepted. Please change the values.


Changed! Thanks for looking into this!

Hello everyone,

we just received an estimate on VZLUSAT-2 deployment from the ION SCV-004, which is currently planned for 31st January 2022 09:49:10 UTC.
