“We have signed the launch agreement for 4 of our picosatellites to launch onboard Bandwagon-4. They will be in orbit on NET June, 2025 — no slips, no delays.”…
According to Bandwagon-4 | Falcon 9 Block 5 | Next Spaceflight
The launch should be at 5:09UTC on Sunday November 2, 2025.
I am participating on the launch as groundstation for the CEVROSAT-1, which is IARU coordinated to 436.025MHz with 9k6 G3RUH GFSK. IARU Sat Coordinator
TLM specs will be published soon.
According to my info, it is the same radio as on GRBalpha, so 9k6 digipeater + there was some possibility of delayed massaging, but I am not familiar with actual FW version yet.
For the next 2 weeks I’ll be kind of busy with the last details of LSF’s PHASMA mission, any help with suggesting satellites/transmitters in DB is more than appreciated. If you need any help on how to create suggestion take a look in Transmitter Suggestions - SatNOGS Wiki and Satellite Suggestions - SatNOGS Wiki.
I’ll try to take a deeper look in this launch the next days.
Thanks, very useful! I’ve updated the first post with the image from the site as usually they remove it after the launch.
From those with a quick search in UHF we have the CEVROSAT-1 and HAVEN-DEMO according to ITU. The rest are either unknown or use S-band, so I’m not going to add them in DB, except if there is a specific interest.
About the TLE, usually due to the nature of the Bandwagon mission we don’t get TLE from celestrak.org like with Transporters ones. so we may need to generate it. I’ll take a look in the next days. If there is any source please share it here
Launch was on time, the satellites are now available for scheduling in Network.
Satellite have been scheduled for the first 14h using the TLE sets of the previous post, the difference in the number of scheduled observations is based on the frequency, the orbit of the satellite and the request by satellite teams:
Also there are signals on 400.500MHz probably LUMEN-1 as it is expected on that frequency, but it could be also HAVEN-DEMO, unfortunately without confirmed details of the transmission of each satellite is difficult to say.
The digipeater looks like the same as the one of GRBAlpha.
This means NOvia path.
By using this Delayed Needronix Digipeater (DNxD) you can delay the repetition of your message by putting @xxx as the first 4 characters of your message where xxx stands for the minutes of the delay.
I’ll prepare a decoder so we would see the messages on the Digipeater Dashboard if uploaded.
By checking again the latest observations It looks like we have two signals one wide around 40KHz bandwidth and one narrow around 9.6KHz.
I would say that the narrow one comes from this launch, for the wide one we need more observations to confirm. If both belong to this launch we need to find out who is who.
EDIT: Checking ITU of both of them and and old FCC record from this post I think that the wide one (if it is confirmed from this launch) is HAVEN-DEMO and the narrow one from LUMEN-1.
