Introduction
The race for 6G technology is heating up, with innovations paving the way for advanced satellite communication systems. The Korea Research Institute of Standards and Science (KRISS) has taken a significant step by developing critical measurement standards that can enhance the reliability of Korea’s low Earth orbit satellites. This article dives into the advancements in three-dimensional communication, the role of waveguides, and how these developments push the boundaries of satellite technology.
The Shift to Three-Dimensional Communication
As our communication needs evolve, the industry is embracing three-dimensional communication models. Unlike traditional two-dimensional setups, which often struggle in difficult terrains such as mountains and oceans, three-dimensional technology ensures fast and reliable communication, eliminating blind spots. This is particularly vital during disasters or conflicts when ground-based networks may be compromised.
The Role of Low Earth Orbit Satellites in 6G
Low Earth orbit (LEO) satellites are central to the future of communication technologies, operating between 200 km and 2,000 km above Earth. One of the leading players in this field is SpaceX with its "Starlink" system. Following suit, Korea successfully launched its first domestically developed small LEO satellite, "NEONSAT 1," to embark on a journey to create a unique "Korean-style Starlink."
Importance of Measurement Standards for 6G Satellite Communication
For the effective commercialization of 6G LEO satellite communication, establishing accurate and reliable measurement standards is paramount. These standards are essential for assessing communication quality, paving the way for reliable verification of domestically developed satellite technology.
Until now, the absence of a measurement standard for Korea’s 6G LEO communication system posed challenges in validating its performance.
KRISS’ Innovations in Impedance Measurement Standards
Establishment of Impedance Measurement Standards
The KRISS Electromagnetic Wave Metrology Group has made remarkable progress by developing an electromagnetic wave impedance measurement standard specifically for waveguides. Waveguides are crucial components in satellite communication systems, facilitating the transmission of electromagnetic waves efficiently.
The research team focused on the X-band frequency range (8–12 GHz), a standard utilized in small LEO satellites developed in Korea. This pioneering work enhances the reliability of the components found in these satellites, providing several benefits:
- Quantitative Assessment: With established measurement standards, important performance metrics such as signal strength, latency, and propagation loss can be evaluated during the satellite prototyping phase.
- Cost and Time Efficiency: Accurate predictions for the necessary communication outputs can lead to custom designs, reducing unnecessary expenses and shortening development timelines.
Distribution of Calibration Technology
KRISS has also developed advanced calibration technology for waveguides that makes it easier to distribute these critical measurement standards to the industrial sector. Traditionally, calibrations for network analyzers needed overseas intervention, incurring high costs and delays. With KRISS’ innovative technology, more accurate calibrations can be performed domestically at a significantly reduced cost.
Dr. Cho Chi Hyun, Principal Research Scientist at KRISS, emphasized that the newly developed standard is adaptable beyond just satellite communication, extending its utility to radar systems and aircraft as well. This versatility highlights the widespread implications of their research.
Looking Ahead: Enhancing National Competitiveness
KRISS remains committed to establishing necessary electromagnetic wave measurement standards across various sectors, including defense and telecommunications. By reinforcing the reliability of satellite components, the research contributes to enhancing national competitiveness in the global tech arena.
This groundbreaking research was published recently in the peer-reviewed journal IEEE Transactions on Instrumentation and Measurement, signaling a bright future for the advancement of LEO satellite technology.
