Quick tech breakdown for the ERMINAZ mission: The satellites use SSDV to split JPEG images into robust packets. These are embedded directly into standardized CCSDS Transfer Frames using Virtual Channel ID 4 (VCID 4) for seamless decoding on Earth. Open Source! 🛸📡 #PocketQube #CubeSat #AMSAT

It's official now! Our three ERMINAZ-2U, -2V and -2X PocketQubes are set for launch 18:18 UTC (20:18 CEST) on October 01 with Transporter-18! #AMSAT #hamradio

Doppler shift: -80 mm/s is about a 2.2 Hz increase in frequency.

Actually we have seen it. -80 mm/s is about a 2.2 Hz increase in frequency.

#RST now ~ 1.5 Msym/s, 780 kb/s data rate according to DSN, likely <7,2> convolutional encoding, classic BPSK.

#RST just turned on by DSN Madrid. Very strong signal, 10 MHz BW on the screen. Data rate 354.5 kb/sec

#BepiColombo came back a bit earlier than expected at 13:48:40 UTC - exciting!!

The moment when #BepiColombo separated and signal disappeared on purpose at the exact time.

AMSAT-DL @amsat-dl.org · 03/09/2026
Indeed we are also watching #BepiColombo from Bochum Observatory with our 20m dish. Weather conditions in Bochum not very favorable at the moment.... it takes 11.5 minutes until signal arrives from 207 Million kilometers at Earth!

The data is important for monitoring space weather and its impact on Earth and radio wave propagation; it is also very important for amateur radio operators and shortwave radio.

In July, Bochum transmitted by far the most data from STEREO-A’s Space Weather Beacon to the NOAA Space Weather Prediction Centre (SWPC). We have been doing this 24/7 since 2009.

Planned maintenance on the #AMSAT #QO100 satellite ground station in Bochum from Thursday (30 July) to Sunday (2 August).📡〰️ All beacons, including LEILA, will be switched off intermittently during this period.

Obviously DSN Madrid is back in business, while DSN Now status display shows offline. Below is Robledo ground station locked-on and doing an uplink sweep. Meanwhile Bochum has been providing space weather beacon data though.

Hayabusa-2 on our 20m antenna today. Even modulation sidebands are visible, but to weak to decode.

AMSAT-DL @amsat-dl.org · 07/07/2026
Tianwen-2 on HGA today and high data rate, likely more pictures and science data is coming...

AMSAT-DL @amsat-dl.org · 06/07/2026
Finally images from Tianwen-2 and Hayabusa2 with their asteroids are published by CNSA and JAXA

On July 4, Tianwen-2 is expected to approach within 20 km of Kamoʻoalewa, marking the start of the mission's most critical phase after a 13-month journey from its May 2025 launch. Doppler measurements from our 20m Bochum antenna indicate no or only small orbit adjustments during the last few day.

Tianwen-2 near #Asteroid Kamoʻoalewa is now over 40 million km away from Bochum and very active over the last couple of days, including orbit maneuvers to further reduce the distance to the asteroid. Thanks to Tammo Jan @radiotelescoop.bsky.social and @telkamp.eu for further Doppler analysis.
