Establishing electromagnetic wave measurement standards to ensure the performance of Korea’s Starlink

The Korea Research Institute of Requirements and Science has established requirements that may reliably confirm the efficiency of Korea’s creating 6G low Earth orbit satellite tv for pc communication system.

Just lately, the communication paradigm is shifting to three-dimensional communication using each air and house. Whereas two-dimensional communication faces limitations in areas corresponding to mountainous areas and oceans the place base stations are tough to construct, three-dimensional communication can present quick companies anytime and wherever with out blind spots. Even within the occasion of battle or disasters that disrupt ground-based networks, communication might be maintained stably.

6G low Earth orbit satellites, which relay knowledge at altitudes near Earth’s floor (between 200 km and a couple of,000 km), are a core infrastructure for three-dimensional communication. A consultant industrial instance is the “Starlink” system, which is being constructed by SpaceX in america. Korea additionally launched its first domestically developed small low-Earth-orbit satellite, “NEONSAT 1,” in April final 12 months as a part of the hassle to construct a “Korean-style Starlink.”

For the profitable commercialization of 6G low Earth orbit satellite tv for pc communication, standards that may precisely measure and consider communication high quality are important. Nonetheless, till now, there was no established measurement customary for our 6G low Earth orbit satellite tv for pc communication system, making it tough to reliably confirm the know-how of domestically developed satellites.

The KRISS Electromagnetic Wave Metrology Group has developed an electromagnetic wave impedance measurement customary for waveguides, that are key parts of 6G low Earth orbit satellite tv for pc communication techniques.

A waveguide is a construction that transmits electromagnetic waves alongside a particular path, able to delivering high-frequency indicators with minimal loss and wonderful sturdiness. It’s used because the sign transmission channel in satellite tv for pc communication techniques. The analysis staff prioritized establishing an impedance measurement customary for the X-band (8–12 GHz) frequency range, which is utilized in domestically developed small low Earth orbit satellites.

This growth of the measurement customary will considerably improve the technological reliability of parts utilized in domestically developed low Earth orbit satellites. With exact measurement requirements, numerous efficiency indicators—corresponding to signal strength, latency, and propagation loss—might be quantitatively assessed in the course of the satellite tv for pc’s prototype part, resulting in enhancements that improve high quality.

As well as, by precisely predicting the required communication output for satellite tv for pc parts, customized designs might be made, which is able to assist scale back pointless prices and shorten the event timeline.

KRISS has additionally developed waveguide impedance calibration know-how to distribute the newly established measurement requirements to the commercial sector. Prior to now, calibrating community analyzers used for impedance measurement required sending tools abroad, which was time-consuming and expensive. Nonetheless, with the brand new home know-how, correct calibration can now be carried out at a decrease value.

Dr. Cho Chi Hyun, Principal Research Scientist of the KRISS Electromagnetic Wave Metrology Group, said, “The standard developed this time can be applied not only to satellite communication, but also to all fields where waveguides are used, such as radar systems and aircraft.”

He added, “We will continue to establish electromagnetic wave measurement standards needed by domestic industries and the defense sector, contributing to the enhancement of national industrial competitiveness.”

This analysis was published in February within the journal IEEE Transactions on Instrumentation and Measurement.
