Keysight to Provide Payload Testing Solution for First SWISSto12 HummingSat Mission

The solution will validate Ku band bent-pipe transceiver payload that will deliver broadcast services for media companies and broadband connectivity for telecom providers

The payload test platform helps ensure a successful payload mission before the satellite leaves the launch pad

Keysight Technologies, Inc. announces that SWISSto12, one of Europe’s fastest-growing satellite and radio frequency (RF) payload manufacturers, has selected the Keysight Payload Test System (PTS) to validate the RF payloads of its first HummingSat geostationary satellite Intelsat 45. The HummingSat is a small, innovative telecommunications satellite developed with the European Space Agency through a public-private partnership with customers, including Intelsat and Viasat.

Launching a telecommunications satellite has no room for error. Once in orbit, each of a satellite’s complex systems and payloads must function flawlessly. This means that satellite manufacturers must thoroughly test each part of a satellite during production and assembly to validate the spacecraft’s payload performance before it leaves the launch pad.

Scheduled for launch in 2026, Intelsat 45 will deliver broadcast services for media companies and broadband connectivity for telecom providers through a Ku-band transceiver. The Keysight PTS provides SWISSto12 with a complete integrated set of instrumentation, signal conditioning, and measurement calibration hardware and control software to extensively and robustly test the HummingSat RF payload.

The PTS connects to the HummingSat payload with a modular switch matrix platform with switchable CalPod Assembly Modules that calibrate the uplink and downlink paths without disconnection. This feature creates a movable software calibration plane that simplifies the production flow by eliminating interruptions that usually accompany periodic calibrations. In addition, the Keysight CodeOne™ software suite interfaces with the SWISSto12 system controllers to provide automated, accurate, and repeatable measurements for all payload test cycles.
