OCC4Sat

A Horizon Europe project on the use of Optical Camera Communication for intra-satellite networking.

Curious about how OCC4Sat actually works? Next week, we're dropping a video explaining how we got this ambitious technology up and running, and how an interesting quirk of digital camera sensors let us get a thousand times better data transfer rates.

Our team just finished integrating the final test assemblies for OCC4Sat! We'll use these to validate our signaling protocols.

Thanks to our project partners at Argotec for fabricating these satellites! It's been incredibly exciting to see our designs in the real world.

[OCC4Sat @OCC4Sat]

In this quick interview, ULPGC's Jaime Andres Aranda Cubillo gives us some context on a simple technology demonstrator we've put together of the technology behind OCC4Sat. This demonstrator uses off-the-shelf hardware to showcase how our algorithms work in practice.

We'd like to wish everyone a happy New Year! Thanks to everyone who's followed the project, and best wishes for 2026!

[OCC4Sat @OCC4Sat]

In case anyone missed it, here's our most recent update video on the project, focusing on the satellite hardware prototypes our partners at Argotec have recently manufactured. This was a huge milestone for the project!

Last week, Jaime Aranda Cubillo, a post-doc working on OCC4Sat, completed a first test of Optical Camera Communication (#OCC) on real hardware.

Jaime helped design our protocols via computer simulations, and finally got a chance to validate these on a test bench he co-developed.

[OCC4Sat @OCC4Sat]

We'll use this to test communications between satellite components in different layouts, to figure out which are most effective. It will also let us put the finishing touches on our signaling protocols. Thanks to Matteo Pontecorvo for his work getting this put together! (2/2)

[OCC4Sat @OCC4Sat]

We just completed a test assembly of our new cubesat mockup! This is a big milestone for the project. This is a piece of hardware that our partners at Argotec have designed and built for integration testing OCC4Sat, letting us see how the system behaves in the real world. (1/2)

[OCC4Sat @OCC4Sat]

Earlier this month, as part of Oulu University's 6G Flagship project, we presented a talk on applications of OCC.

Jose Rabadan, our project coordinator, discussed how OCC can be used in specialized and constrained environments like the interior of a satellite.

[OCC4Sat @OCC4Sat]

OCC4Sat's Jaime Cubillo demonstrates a functional prototype of our optical camera communications package, in a to-scale mockup of a cubesat.

Simple one-to-one scale model allows us to validate our assumptions about the system in the real world and refine our signaling protocols.

[OCC4Sat @OCC4Sat]

Projects like OCC4Sat involve collaboration between many different companies. In this interview, ULPGC's Jose A. Rabadan Borges walks us through how he works to keep everyone on the same page and ensure project objectives are delivered successfully.

What does an R&D Project Manager do?

In this quick interview, Argotec's Marco Giuliani takes us through a typical day working on a research and development project like OCC4Sat.

Here's our hardware test platform sending a "Hello world" test message using light.

Our test platform uses a custom Luxeon Rubix LED PCB provided by @lumileds .

In addition to R, G and B LED elements, we have a separate 450nm royal blue element, adding another data channel.

What does a thermomechanical engineer actually do?

Argotec's Matteo Pontecorvo walks us through his role on the OCC4Sat project, and how his work helps ensure our satellite won't overheat or break down in the harsh environment of space

Special thanks to @Argotec_Space for hosting this interview!

[OCC4Sat @OCC4Sat]

How do you keep an aerospace project on track?

Francesco Ferrari, an engineer at Argotec, gives us some insights on the role of a systems engineer in an R&D project like OCC4Sat, and how he helps contribute to testing and delivery of key objectives.

Last week, our team got together for an in-person meeting! We worked together to plan out the next phase of the project, finalize our approach to signaling protocols, and make key decisions about prototyping hardware. Thanks to @Argotec_Space for hosting this gathering!
