Challenges of NR-NTN testing
NR-NTN satellites operate in low earth orbit (LEO). The smaller coverage areas of LEO satellites require more frequent handovers to maintain continuous service. Depending on the geographical location, interorbit handovers may also be necessary. Accurate knowledge of satellite and user equipment (UE) positions and velocities (ephemeris information) is essential for effective link management and compensating for signal impairments. Additionally, long-term testing scenarios are complicated by manual deployment and handover processes, which can introduce errors, cause delays and demand significant resources.
The Constellation Insight Tool addresses these challenges by providing intuitive visualization and management of satellite constellations and UE locations. It allows for automated deployment and handover, integrates precise ephemeris data to simulate realistic mobility and impairment compensation and supports complex handover scenarios. When used in conjunction with the CMX500, the Constellation Insights Tool streamlines the configuration and deployment of NR-NTN systems, reducing manual intervention and enhancing the reliability and efficiency of NTN testing and management.
