SKY Perfect JSAT innovation lab uses pioneering NTN testbed
VIAVI Solutions and Rohde & Schwarz have announced that SKY Perfect JSAT Corporation has selected their joint NTN testbed for its recently unveiled “Universal NTN Innovation Lab”.
SKY Perfect JSAT is a pioneer in satellite communications, the largest provider of multichannel pay TV broadcast services in Japan, and operates the largest satellite communications business in Asia. The NTN testbed will enable technical testing to 3GPP 5G NTN standards.
Launched in November 2024, the NTN Lab at the Yokohama Satellite Control Center (YSCC) is an environment equipped for technical NTN testing. The NTN Lab will serve as a testing hub for the realization of the “Universal NTN”, a pioneering concept aiming to deliver robust and reliable connectivity anywhere, anytime. Universal NTN leverages Geosynchronous Earth Orbit (GEO) and non-GEO satellites, and High-Altitude Platform Stations (HAPS) with technology that enables automatic routing to the optimal communication path.
Supporting the SKY Perfect JSAT NTN Lab, VIAVI and Rohde & Schwarz have delivered a joint NTN testbed covering LEO, MEO and GEO satellites. Use cases include: validating end-to-end connectivity and performance; measuring quality of service over large coverage areas with different types of User Equipment (UEs) ; end user application performance while coping with distance, speed and mobility of both satellite and UE; and reliability and stability. The NTN testbed includes:
- The VIAVI TM500-AS2, a streamlined version of the flagship used by global network equipment manufacturers for base station testing, fully supporting the 3GPP protocol including Doppler and delay pre-compensation.
- The CMX500 mobile communication network tester, with channel emulation and fading in a single box, including all 3GPP fading profiles.
- The VIAVI TeraVM Real Data Applications (RDA) engine, enabling rich and realistic application and traffic scenarios to test system performance under varying conditions.
Initially, testing at the NTN Lab will target GEO satellites operating in the Ku-band to enable high-capacity, wide-bandwidth communications. The NTN Lab’s initiatives will focus on 5G NTN technologies and support the development of new communication technologies utilizing satellite communications.
