Rohde & Schwarz collaborates successfully with the Taiwan Space Agency to develop a dual-function satellite test solution

In an efficient collaboration, Rohde & Schwarz has developed the first integrated testing solution for the Taiwan Space Agency (TASA), enabling seamless EMC and antenna measurements within a single chamber. The project underscores the growing demand for advanced satellite testing systems as Non-Terrestrial Network technologies evolve.

Rohde & Schwarz has taken a significant step forward in satellite testing technology by delivering a fully customized 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 analyzer, R&S®AMS32 customized 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 minimizes 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

For Rohde & Schwarz, this project reinforced its expertise in integrating third-party components. The collaboration between a third-party supplier and TASA highlights the company’s adaptability in addressing specialized customer requirements while maintaining high standards of performance and reliability.

As satellite-based connectivity becomes more integral to global communications, the industry faces rising expectations for robust and reliable testing processes. Satellites play a critical role in ensuring seamless communication across a wide range of applications, from remote sensing tools to mobile networks.
