Are you planning to add LabSat to SatNOGS? I see it’s polish and on amateur frequencies - I think that it was built by a private company (SatRevolution) in cooperation with Wrocław University of Science and Technology. I suspect they should be using same modulation as STORK-4/5 (FSK 9600) but I’m not sure.
Hello,
PION-BR1 Wiki: Home · pion-labs/PION-BR1 Wiki · GitHub
We also created a similar challenge as ESA did on the past: Calling All Radioamateurs · pion-labs/PION-BR1 Wiki · GitHub
Thank you,
Calvin
There is plenty of information missing: what should be expected RF wise?
Thanks @calvin, could you also share sample demodulated frames of the satellite and how to decode them?

I’ve just removed from the above lists PYCUBED-1 and TARTANARTIBEUS-1. Both seem not to be in this launch. If someone has different info please share it.
1805 observations have been scheduled for the next 48h, the difference in quantity is due to the frequency of the satellites (some transmit on the same one as you can see in previous posts) and due to the mode of the satellites (as network stations are not able to handle LoRa we tend to schedule less observations for LoRa satellites):

To station owners, feel free to change the satellites that are scheduled to your stations if you have a preference.
Separation confirmed for 6 FOSSASAT-25 satellites travelling in a trail, we transmit at 401.7MHz GFSK and LORA beacons every 30 seconds to 60 seconds. GFSK, +/-5KHz, 9k6, 0xFF. This should be decodable by satnogs and the many satellites are all in a trail on the same frequency. The callsign is ASCII and contains FOSSA-X
Didn’t have high expectations with the max elevation only being 7° on this first pass. So, nothing seen using a number of different LoRa devices including one on the TinyGS network.
Also monitored much of the 436-437 MHz spectrum used by the non-LoRa sats from this deployment and didn’t see any signals. But again, from my location it would be extremely rare to see much below 10, or even 20 degrees.
Better opportunities coming tonight and in the coming days - I’ll hope to have something to contribute.
Unfortunately I didn’t find this information in public earlier. I’ll add the transmitters later today and I’ll try to schedule a couple more observations.
… good to see that at least some commercial satellite operators finally decided to be “good” and move out of the 435-438 MHz amateur satellite band …
The passes are still low, however we have received probably 3 of the satellites:
SanoSat-1:
SatNOGS Network - Observation 5292603 - visible and audible CW at ~340s and RTTY FSK at ~200s
SatNOGS Network - Observation 5292601 - very faint signal at ~350s
Tevels:
https://network.satnogs.org/observations/5292936/
which is confirmed also by @EU1SAT:
NuX-1:
https://network.satnogs.org/observations/5293944/
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.
Hi,
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
https://cdn3.beun.edu.tr/grizu263/2cbe4406cd5ce32d3eeea1645b3cde2c/grizu263acommguideen.pdf
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
Bit Rate 2.4 kbps
First signal from Grizu-263A is confirmed! It seems correct frequency is 435.675Mhz.
