R&S collaborates successfully with the Taiwan Space Agency to develop a dual-function satellite test solution
Rohde & Schwarz has taken a significant step forward in satellite testing technology by delivering a fully customised solution to the TASA. For the first time, Rohde & Schwarz integrated EMC and antenna measurement capabilities into a single test chamber, addressing a complex challenge in satellite payload testing. The innovative system, now operational at TASA’s facility, reflects the growing need for advanced satellite testing methodologies. With the increasing adoption of Non-Terrestrial Network (NTN) technologies, precise validation of satellite performance in complex environments is becoming essential. This includes ensuring seamless integration between satellites and cellular base stations — an area where conventional testing methods often fall short.
The project’s complexity stemmed from TASA’s dual testing requirement: a single chamber capable of performing both EMC and antenna measurements. To meet this demand, Rohde & Schwarz’s solution includes a R&S ZNA43 vector network analyser, R&S AMS32 customised measurement software, and engineering services. The system also incorporated a Compact Antenna Test Range (CATR) reflector, developed in partnership with a Taiwan third-party supplier.
A key innovation in the project was the introduction of a patented diamond-shaped reflector design. This reflector minimises interference within the chamber and reduces interactions between the reflector, feed, and Device Under Test (DUT) positioner. The result is improved accuracy and reliability in measuring complex satellite payloads.
