Rohde & Schwarz, Taiwan Space Agency Build Dual Satellite Test

• Rohde & Schwarz integrates EMC and antenna testing in a single chamber for TASA.
• Patented diamond-shaped reflector design enhances accuracy by minimizing interference in satellite testing.
• Collaboration with Taiwanese supplier ensures customized, reliable testing for Non-Terrestrial Network technologies.

Rohde & Schwarz has achieved a milestone by providing the Taiwan Space Agency (TASA) with an innovative, fully customized satellite testing solution. The system is the first of its kind in satellite payload testing, being able to integrate electromagnetic compatibility (EMC) and antenna measurement capabilities into a single test chamber. Available now at the facility of TASA, the solution addresses the increasing need of advanced testing methodologies that is brought by the evolution of Non-Terrestrial Network (NTN) technologies.

These technologies require precise validation of satellite performance, particularly for seamless integration with cellular base stations, where traditional testing methods often prove inadequate.

The project addressed TASA’s unique need for a single chamber to conduct both EMC and antenna measurements. Rohde & Schwarz delivered a tailored solution featuring the R&S ZNA43 vector network analyzer; R&S AMS32 customized measurement software, and expert engineering services. In collaboration with a Taiwanese third-party supplier, the system incorporates a Compact Antenna Test Range (CATR) reflector, enhancing its testing capabilities.

A standout feature is the patented diamond-shaped reflector design, which minimizes interference within the chamber and reduces interactions between the reflector, feed, and Device under Test (DUT) positioner. This innovation ensures greater accuracy and reliability in testing complex satellite payloads. The project highlights Rohde & Schwarz’s expertise in integrating third-party components while meeting TASA’s specialized requirements, maintaining high performance and reliability standards.

As satellite-based connectivity becomes vital for global communications, including mobile networks and remote sensing, the industry faces increasing pressure for robust testing processes. This collaboration underscores Rohde & Schwarz’s leadership in addressing complex challenges in satellite testing, reinforcing its role in advancing NTN technologies.
