Vtwin 524 36 - Esa

Each pod carries a QR‑code‑enabled beacon. Schools across Europe can track a pod in real time, receive raw telemetry, and even upload a short student‑produced video that will be displayed on the pod’s exterior LED strip during its orbit. In this way, VTWIN becomes a living classroom, bringing the physics of orbital mechanics into the everyday lives of children.

The VTwin series is known for its 1U or 2U rack-mountable form factor (depending on cooling options). The 524 36 model compresses 1.7 kW of regulated power into a chassis that takes up minimal real estate in a 19-inch rack. esa vtwin 524 36

At its core, the ESA VTwin 524 36 is a high-force, permanent magnet shaker system. It belongs to ESA’s prestigious "VTwin" series, known for dual-coil technology and exceptional field uniformity. Each pod carries a QR‑code‑enabled beacon

The "524" designation refers to the shaker’s force rating (approximately 5,240 lbs or 23.3 kN sine force), while the "36" typically indicates the armature diameter (3.6 inches or 91 mm). This combination makes the unit a mid-range powerhouse—powerful enough for large component testing yet precise enough for sensitive accelerometer calibration. The VTwin series is known for its 1U

The armature top plate includes a precision-machined 10-32 threaded hole exactly at the vibration axis center line. This allows direct mounting of a reference accelerometer without fixturing errors.
