Public Information: List of publications now publicly available

Added by Omiros Papadatos Vasilakis 3 months ago

Dear OPS-SAT Experimenter community,

We are happy to announce that up to this date we count already over 200 experiments registered with us. In addition to publications on the spacecraft itself, more and more papers are being released featuring experiment results gained by OPS-SAT, and by now the mission has been subject to numerous international conferences and featured in prestigious journals.

With the 3 year anniversary of OPS-SAT in orbit coming up, we have put together a list of publications, visualizing the scientific impact of the mission, which you can find [[here|]] [1].

Thank you for the successful cooperation, we are looking forward to further experiments,

Best wishes,
The OPS-SAT Team


Public Information: OPS-SAT Experimenter campaign on OSIP

Added by Tom Mladenov almost 2 years ago

Dear OPS-SAT Experimenter community,

We are glad to announce that a new campaign [1] dedicated to exploring and supporting new experiment ideas on OPS-SAT was just launched on the OSIP platform!
Experiment proposals can be submitted until May 23rd and selected ideas will receive funding for the development and deployment of the experiment.

OSIP has reversed the classic approach of engaging with ESA. Whereas the Agency typically invites industry and academia to apply to work on specific research or technology developments, OSIP seeks ideas from the wider community and then ESA helps find the most appropriate mechanism to support the implementation of the most novel ideas.

Update: Existing OPS-SAT experimenters are also encouraged to apply. The only logical restriction is that if your experiment was already executed 1 or more times on-board the spacecraft, then the proposal submitted to the OSIP platform should be an evolution.

Kind regards,


Public Information: OPS-SAT Experiments First Results

Added by Georges Labrèche about 2 years ago

Dear OPS-SAT Experiment Community,

I am writing with the great news that the first non-ESA experiments have been executed on OPS-SAT and the results are impressive. ESA released the following web article today. There are lots of links in that page to the experimenter's own press releases, the photo archive on Flickr etc.

It will not be the last as we have quite a few experiments in the pipeline.

I would also like to draw your attention to the experimenter portal - which Georges Labrèche has updated with some latest news and presentations. There is some good information there - including a video of a live pass the team made at the Open Source Cubesat Workshop in December and demos.

Finally I would like to remind you that experiments are entirely free up until Nov 2021. After that point ESOC cannot continue to operate the mission for free and so we will be asking the Member States to contribute. If we do not cover the cost somehow then the mission will be terminated. We will not charge the experimenters of course but if any of you know your ESA delegate (please find out who they are, as I cannot tell you) then please let them know what you are doing on this platform and that you would like it to continue after Nov 2021. It would be such a shame to turn off the mission when we still have not fully realised its potential! To help communicate this, I attach a simple concept presentation that you can distribute. It is also on the experimenter portal.

All the remains is for me to wish you all a merry Christmas and thank you for keeping faith with us during those difficult days in the commissioning. With your help, 2021 will the year of OPS-SAT-1 - and maybe the start of OPS-SAT-2!

Best regards,
Dave Evans

Amateur Radio Information Bulletin: OPS-SAT Image Gallery, GRCon20 and other news

Added by Tom Mladenov about 2 years ago

Recently we have also been publishing all images taken by OPS-SAT in-orbit on Flickr!
You can find the album at:

In other news, in September we also presented at the GNU Radio GRCon20 online conference.
You can find the paper here:
And the Presentation:

We received a lot of positive and constructive commends and this is also in part thanks to the Radio Amateur community!

Stay tuned and stay safe!

Kind regards,
OPS-SAT Flight Control Team

Amateur Radio Information Bulletin: First images from OPS-SAT

Added by Tom Mladenov over 2 years ago

The first images taken by the High-Definition camera on OPS-SAT have officially been published and can be found at:

Still in commissioning, OPS-SAT will soon be crossing into the experimental phase of the mission where innovative hardware and software experiments will be executed.

Amateur Radio Information Bulletin: Decoding OPS-SAT on Windows

Added by Tom Mladenov about 3 years ago

Good news for Windows users! DK3WN has developed a beacon decoder for OPS-SAT that can be used in conjunction with the popular UZ7HO soundmodem.
Demodulated FM audio from any SDR receiver software is piped to UZ7HO and a TCP/IP KISS interface to the DK3WN Beacon decoder allows for the parsing of the OPS-SAT beacon frames.

DK3WN has also experimented with feeding 48kHz sampled FM demodulated audio to the gr-opssat GnuRadio application and presents the results.

Amateur Radio Information Bulletin: OPS-SAT Status Update 14/01

Added by Tom Mladenov about 3 years ago

The OPS-SAT Flight Control Team is currently in the process of uploading an update to the on-board software.
This was done in reaction to the discovery of a safety bug in the operation of the S-band transmitter.
The update will ensure safe operations of the transmitter during S-band passes with ESOC.

All power and attitude parameters of the spacecraft are nominal.
No payloads have been turned on yet, once the S-band link is brought into safe service after the update, payload
commissioning will start which is on schedule and planned for late January/early February.

Kind regards,

Amateur Radio Information Bulletin: OPS-SAT Status Update and TLE

Added by Tom Mladenov about 3 years ago

The ESOC Flight Control Team wants to say a massive thank you to the Radio Amateur community!
The observations sent to us have been extremely useful in the early operations so far.

Due to limited Telemetry, all beacon observations are still more than welcome and are very useful to us.
We will continue to provide updates as operations progress.

Various sources and doppler observations indicate that object with NORAD ID 44878 (2019-092F) is OPS-SAT.
