A satellite radio doesn’t stop needing updates the day it ships. Over the past weeks we have released new firmware for six Satlab products: our SRS-3 and SRS-4 TMTC radios, the SRX-8 high-speed transmitter, and our AIS, ADS-B and LoRa payloads. A few highlights: SRS-4: a new bootloader with two firmware slots that back each other up. Both can be updated remotely using the new SLIM file format. We also widened the AFC pull-in range to 100 kHz at higher symbol rates and cut idle power. SRS-3: faster Reed-Solomon and convolutional coding with unchanged error-correction performance, plus new telemetry showing how many errors the FEC corrected in each frame. SRX-8: improved output power accuracy across temperature extremes, and GSE framing aligned with ETSI TS 101 162. AIS, ADS-B and LoRa payloads: stability and robustness fixes, a smoother upgrade path for AIS, and a new store mirror service on ADS-B. Across all products, the user manuals now acknowledge the open-source components we build on.

Our VDES payload technology has been selected by ESA for ALCYON, a study demonstrating next-generation maritime and aviation surveillance from satellites, as part of the IRIS² programme. VDES (VHF Data Exchange System) builds on the AIS technology used today to track ships, adding greater data capacity and two-way digital communication. Satlab is delivering the VDES payload for the study, working alongside Kinéis, Thales Alenia Space, and ESSP. This builds directly on our flight heritage — our MARIOT payload was launched aboard SpaceX's Transporter-6 mission in January 2023, giving Satlab proven, in-orbit VDES experience going into ALCYON.

Satlab has been selected by ESA to deliver VDES payload technology for ALCYON — a European satellite project demonstrating next-gen maritime and aviation surveillance from orbit. ALCYON is led by French satellite operator Kinéis, bringing together a European consortium including Thales Alenia Space and ESSP. The project will demonstrate two services from low Earth orbit: maritime surveillance based on VDES, and aeronautical surveillance using satellite reception of ADS-B — part of ESA's Low-LEO Pre-operational and De-risking Activities under the IRIS² programme. Satlab's contribution builds on more than 10 years of experience with satellite-based AIS, and on flight-proven VDES technology — including our MARIOT payload, launched aboard SpaceX's Transporter-6 mission in January 2023. Subscribe for updates as the project develops.

Satlab joins a European industry consortium selected by ESA to demonstrate next-gen satellite surveillance for ALCYON, delivering the VDES payload alongside Thales Alenia Space and ESSP. Led by Kinéis, ALCYON is an in-orbit validation mission demonstrating two services from low Earth orbit: maritime tracking via VDES, and aeronautical monitoring via satellite-received ADS-B — a key building block in ESA's work under the IRIS² programme for EU secure connectivity. It's a great opportunity for Satlab, based in Aalborg, to help shape the surveillance solutions of tomorrow as part of a major European space initiative. Subscribe to stay in the loop.
