As part of our continuous innovation journey and our commitment to exploiting Additive Manufacturing technologies, we are steadily turning advanced concepts into real, high-impact applications. Following the success case of the injector holder developed with our subsidiary Isotta Fraschini and presented at Formnext (Frankfurt), we are excited to share a new milestone.

We are proud to announce that, together with our subsidiary IDS, we have successfully developed two components using cutting-edge Additive Manufacturing technology.

The first product, the Notch Filter — manufactured through 3D printing and integrated within a Satcom On The Move (SOTM) communications antenna — offers a solution designed to increase the isolation between the antenna’s transmitting and receiving circuits, thereby enhancing system performance and reliability. The second project, the RF Corner Reflector for UAV application, was developed to meet the need for a light and effective device for electromagnetic engineering.

Additive Manufacturing - an innovative approach, also known as 3D printing, that builds components by adding successive layers of material based on a digital model - enabled the production of both components, optimizing their weight, quality, and performance confirming the advantages of this innovative technology and further underscoring our commitment to pioneering development, towards a more innovative future.

📢 Introducing the GlobalGeoTree Dataset!
🌳 A large-scale multimodal dataset for global tree species classification, with 6.26M geolocated samples from 221 countries.
🛰️ Each sample includes Sentinel-2 time series and 27 environmental variables (climate, geography, soil).
🌍 Covers 275 families, 2,734 genera, and 21,001 species across taxonomic levels.
🧠 GlobalGeoTree-6M supports large-scale pretraining, while GlobalGeoTree-10kEval enables zero-shot and few-shot evaluation.
🔎 Ideal for biodiversity mapping, species-level monitoring, and multimodal EO models.

Following a recent drone prosecution by the IAA, the drone operator pled guilty and agreed to share their experience to help educate the drone community.
It’s important to remember that flying a drone makes you a pilot and understand your responsibilities before you take to the skies.

[Starlink @Starlink]

On December 17, Starlink experienced an anomaly on satellite 35956, resulting in loss of communications with the vehicle at 418 km. The anomaly led to venting of the propulsion tank, a rapid decay in semi-major axis by about 4 km, and the release of a small number of trackable low relative velocity objects. SpaceX is coordinating with the @USSpaceForce and @NASA to monitor the objects.

The satellite is largely intact, tumbling, and will reenter the Earth’s atmosphere and fully demise within weeks. The satellite's current trajectory will place it below the @Space_Station, posing no risk to the orbiting lab or its crew.

As the world’s largest satellite constellation operator, we are deeply committed to space safety. We take these events seriously. Our engineers are rapidly working to root cause and mitigate the source of the anomaly and are already in the process of deploying software to our vehicles that increases protections against this type of event.
