SKY Perfect JSAT Launches Universal NTN Innovation Lab

In a significant move toward revolutionizing satellite communications, SKY Perfect JSAT Corporation has recently unveiled its "Universal NTN Innovation Lab," aiming to enhance connectivity across various terrestrial and non-terrestrial networks. This initiative is made possible through a powerful collaboration with industry leaders VIAVI Solutions and Rohde & Schwarz.

A Pioneer in Satellite Communications

SKY Perfect JSAT holds the title of Japan's largest multichannel pay-TV broadcaster and is a leader in satellite communications across Asia. Their new innovation lab, launched in November 2024 at the Yokohama Satellite Control Center, is designed to serve as a dedicated testing hub focused on Non-Terrestrial Networks (NTN).

The NTN Innovation Lab emphasizes the development of robust connectivity solutions that leverage both Geosynchronous Earth Orbit (GEO) and non-GEO satellite systems, as well as High-Altitude Platform Stations (HAPS). By integrating advanced routing technology, the lab aims to ensure seamless communication pathways regardless of geographical barriers, effectively providing connectivity anywhere, anytime.

Joint Venture with VIAVI and Rohde & Schwarz

SKY Perfect JSAT partnered with VIAVI Solutions and Rohde & Schwarz to create a state-of-the-art NTN testbed that incorporates Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and GEO satellites. The collaborative efforts focus on several key use cases including:

• - Validating end-to-end connectivity and performance across diverse satellite systems.
• - Measuring quality of service over extensive coverage areas using various types of User Equipment (UE).
• - Assessing application performance while managing the complexities introduced by distance, speed, and mobility within the communication network.

Advanced Testing Tools

The NTN testbed is equipped with cutting-edge technology to facilitate thorough testing and validation processes. Key components include:

• - The VIAVI TM500-AS2, renowned for its capabilities in base station testing and compliance with 3GPP protocols.
• - The Rohde & Schwarz CMX500, a versatile mobile communication network tester that integrates channel emulation and fading profiles in one solution.
• - The VIAVI TeraVM Real Data Applications (RDA) engine, which creates realistic testing scenarios to evaluate system performance under varied conditions.

Initiatives at the NTN Lab will initially target the testing of GEO satellites operating in the Ku-band, providing high-capacity, wide-bandwidth communications essential for modern connectivity demands.

Pioneering 5G NTN Technologies

By focusing on 5G NTN technologies, SKY Perfect JSAT, alongside its partners, aims to facilitate the development of groundbreaking communication technologies supported by satellite systems. Hiroyuki Yagihashi, Deputy Group President of Business Innovation at SKY Perfect JSAT, expressed pride in launching Japan's first geostationary satellite-based 5G NTN demonstration, which marks a significant milestone in the company's ongoing efforts to innovate and expand its services.

"We appreciate the support and advanced technologies from our partners, VIAVI Solutions and Rohde & Schwarz, that will help accelerate technology demonstration and use case development for the NTN business," Yagihashi stated, reinforcing the collaborative spirit driving this innovative project.

Future Implications

The establishment of the Universal NTN Innovation Lab represents a critical step in enhancing satellite-based communication technologies, paving the way for advancements that can greatly benefit commercial and governmental infrastructure. With a commitment to integrating satellite data into broader connectivity strategies, SKY Perfect JSAT is poised to contribute significantly to disaster preparedness, national security efforts, and the development of a super-smart society.

With expertise that spans over 35 years in delivering reliable broadcasting solutions, the company is now focusing on expanding its capabilities in the Space Intelligence Business and enhancing both commercial and military connectivity needs. This endeavor is expected to solidify its market position and facilitate more robust and versatile satellite communication networks for future generations.

As we move forward, the synergy between SKY Perfect JSAT, VIAVI Solutions, and Rohde & Schwarz is set to redefine the future of connectivity and communications, ultimately benefiting users and operators globally.
