Rohde & Schwarz and its partners unveil new satellite payload testing innovation at Space Tech Expo Europe 2025

Rohde & Schwarz and its partners unveil new satellite payload testing innovation at Space Tech Expo Europe 2025 Rohde & Schwarz, in collaboration with Connektica, NANOWAVE Technologies, and Expleo, will showcase a next-generation satellite payload test bench demonstrator at Space Tech Expo Europe 2025. The new solution targeting space and NewSpace OEMs, will be hosted on the Expleo booth at Europe's premier space industry event, stand A38 in Hall 4.

The FSW signal and spectrum analyzer from Rohde & Schwarz is part of the new satellite payload testing solution.

Built specifically for the event, the custom-designed Hardware-In-the-Loop (HIL) test bench integrates advanced RF instrumentation to simulate and analyse satellite payload performance under realistic conditions. The solution is engineered to accelerate development cycles, reduce errors, and scale validation across R&D, manufacturing, and maintenance environments.

The new test bench is the result of the collective know-how of the four companies. Expleo's systems engineering, AIT (assembly, integration and testing) and RF test systems expertise, proven in delivering test solutions for numerous Space programmes, have been combined with Connektica's aerospace-grade MES platform for AIT automation, NANOWAVE Technologies' high-reliability RF subsystems with over 6,500 transmit/receive modules, and precision test and measurement instrumentation aligned to EN9100 standards from Rohde & Schwarz.

Valentin Martelet, Space Offer Lead, Expleo, said: With more and more organisations trying to leverage the unique benefits which space data can unlock for their businesses, accelerating time-to-market and operational efficiency of satellite development is of huge importance to the industry. This test bench is the composite of niche and in-demand expertise from four industry leaders, which has been proven time and again on successful space missions.

Ralph Kirchhoff, Market Segment Manager Aerospace & Defence at Rohde & Schwarz, emphasized: Modern satellite payloads demand a holistic approach to testing, moving beyond component-level verification. Rohde & Schwarz is proud to contribute instrumentation that facilitates comprehensive, system-level validation within this innovative test bench. By ensuring the cohesive performance of the entire setup, we're helping to accelerate the delivery of reliable and high-performing satellite solutions.

Jeremy Perrin, CEO, Connektica, added: What we're showing in Bremen is a blueprint for industrialising payload validation: system-level testing with the AIT workflow automated, data unified, and repeatability built in from day one.

Ralf M. Bertenburg, VP Sensor Technologies & SW Development at Nanowave, comments: As a designer and manufacturer of highly reliable RF payload assemblies it is mandatory to have fast and reliable test capabilities because of the vast amount of evaluated data points per unit necessary to qualify for their critical and demanding mission in space. We are happy to support this activity with one of our latest K/Ka-band Transmit/Receive assemblies that is used in high quantities on huge satellite constellations today.

The solution will be exhibited at Space Tech Expo in Bremen from November 18 to November 20 at Expleo booth stand A38 in Hall 4.
