R&S and the Taiwan Space Agency collaborate on creating a dual-purpose satellite test solution
Rohde & Schwarz Addresses Complex Satellite Payload Testing with Dual-Function Solution
In a significant development for the satellite industry, Rohde & Schwarz has delivered a customized solution to TASA (Taiwan Space Agency) that addresses the complex challenge of satellite payload testing. The innovative system integrates electromagnetic compatibility (EMC) and antenna measurements into a single test chamber, enabling seamless switching between EMC compliance/immunity tests and antenna/over-the-air (OTA) characterization without moving the device under test (DUT).
The solution's key components include the R&S ZNA43 vector network analyzer, which provides high-dynamic-range S-parameter and gain/phase measurements up to 43.5 GHz, covering essential satellite communication bands. This allows for precise calibration of active antenna arrays and feed networks.
The R&S AMS32 customized measurement software, another integral part of the system, synchronizes chamber control, automated test sequencing, and consistent data capture for both EMC and antenna workflows. This ensures traceability and supports continuous integration/continuous deployment (CI/CD)-style testing operations.
A notable innovation in the project is the use of a Compact Antenna Test Range (CATR) reflector, featuring a patented diamond-shaped reflector design developed in partnership with a Taiwan third-party supplier. This reflector minimizes interference within the chamber by reducing blockage and scattering among the reflector, feed, and DUT positioner. The result is a cleaner and quieter test zone with lower multipath effects and higher measurement fidelity for complex satellite payloads.
The design philosophy of the system combines global-grade metrology with localized integration, demonstrating adaptability to include third-party components while maintaining high performance, serviceability, and cost control relevant for regional space agencies like TASA.
This integrated approach directly responds to the increasing demands of Non-Terrestrial Network (NTN) technologies, where precise satellite performance validation in complex environments is essential for ensuring seamless satellite-to-cellular base station interoperability. Conventional separate testing methods often fall short in meeting this challenge.
The Rohde & Schwarz-TASA project is a reflection of the growing need for advanced satellite testing methodologies. The collaboration between Rohde & Schwarz, TASA, and a Taiwan third-party supplier is crucial in this project, demonstrating the company's adaptability in addressing specialized customer requirements. This project underscores Rohde & Schwarz's commitment to maintaining high standards of performance and reliability in the satellite industry.
