Keysight provides test solutions for SWISSto12 satellites

HummingSat is a new family of small, compact communications satellites, co-developed with the European Space Agency in a public-private partnership and customers including Intelsat and Viasat.

There is no room for error in communications satellite launches. Once in orbit, each satellite is a complex system, and its payload systems must operate flawlessly. As a result, satellite manufacturers must thoroughly test every part of a satellite during manufacturing and assembly to confirm the payload’s performance on the spacecraft before liftoff.

Scheduled to launch in 2026, Intelsat 45 will provide broadcasting services to media companies and broadband connectivity to telecommunications providers via Ku-band (Ku-band) transponders. Keysight’s PTS solution provides SWISSto12 with a complete suite of instrumentation, signal shaping and measurement calibration hardware, and control software to exclusively test the HummingSat RF payload reliably.

The PTS connects the HummingSat payload to a modular switching matrix platform, which includes interchangeable CalPod Assembly Modules for calibration of uplink and downlink paths without disconnection. This creates a software-shiftable calibration plane, simplifying the manufacturing workflow by ensuring that routine calibrations do not disrupt operations.

The Keysight PTS solution uses high-quality test equipment and has a flexible, modular structure that is easy to upgrade. The SWISSto12 PTS configuration includes the E8257D PSG Analog Signal Generator, the M9837A PXIe Vector Network Analyzer, and the N9030B PXA Signal Analyzer.

“With the goal of optimizing and industrializing our HummingSat assembly and test processes, we are pleased to announce the selection of test leader Keysight Technologies and Keysight’s Payload Test System to validate that our GEO satellite payload systems meet all performance parameters critical to mission success,” said Emile de Rijk, CEO and founder of SWISSto12.
