Launcher telemetry

Réaltra develops onboard imaging, positioning, networking and data-handling technologies that allow mission teams to see and understand critical launcher events—from liftoff and stage separation through payload deployment.

Our flight heritage includes live HD mission imagery on Ariane 5 (JWST launch) and Ariane 6, GEKI GNSS on the maiden flight of Ariane 6 and CryoCam imaging for cryogenic environments during ascent. VIKI brings these capabilities together in autonomous or integrated architectures, combining camera and any other sensor streams with H.265 compression, deterministic Ethernet or TTE networking and CCSDS encoding for transmission to the ground.

This modular approach targets reduced mass, cost and integration complexity without compromising reliability or mission viability.

Experiment activity aboard the International Space Station

PLDR · INTERNATIONAL SPACE STATION

Microgravity data that keeps working.

PLDR—the Payload Data Recorder—was developed by Réaltra and remains operational aboard the International Space Station. It provides local microgravity measurement at the point of use and is paired extensively with other onboard experiments, giving payload teams valuable environmental context for interpreting sensitive results.

The underlying measurement capability can be adapted for future missions where local microgravity knowledge may improve sensitivity and reduce error, including optical, communications, quantum and other precision applications.

ESA PLATO · 2027

M-class science mission

Réaltra hardware is scheduled to fly on ESA's PLATO exoplanet mission in 2027. The programme extends our experience from launcher and in-orbit operations into a major European science mission, demonstrating the company's ability to develop dependable space electronics for demanding satellite applications and long-duration mission requirements.

Optical communications

Under the ESA AIDAN Next public-private partnership, Réaltra is developing a Terminal Control Unit for the optical head of a communications satellite. The programme advances the control electronics required for next-generation optical links, applying Réaltra's experience in reliable, mission-specific electronics to a high-capacity satellite communications architecture.
