How to Validate Coverage Across 3D Non-Terrestrial Networks

+ 3D NTN Channel Emulation Solution

Emulate Satellite, HAPS, and UAV Layers as One System

6G non-terrestrial coverage will combine three flying layers — GEO/MEO/LEO satellites, high-altitude platform stations (HAPS), and unmanned aerial vehicles (UAVs) — each with distinct geometry, mobility, and propagation characteristics. Ensuring seamless coverage requires reconstructing all three layers concurrently in the lab, rather than testing each link in isolation.

Engineers can emulate synchronized, multi-node satellite, HAPS, and UAV channels — including high Doppler shift and long delay for satellite links, quasi-stationary stratospheric drift for HAPS, and agile low-altitude mobility with frequent line-of-sight blockage for UAVs — to validate realistic cross-layer handover, mobility management, and end-to-end performance for devices and base stations under 3D NTN conditions using emulation testbeds.

3D NTN Channel Emulation Solution

Validating 3D NTN coverage requires concurrent channel emulation of every non-terrestrial layer as well as the geometry and mobility data that drive them. The PROPSIM-based S8825A Satellite and Aerospace Channel Emulation Toolset provides the RF channel emulation core — supporting K-band (20/30 GHz) operation via the M1742A transceiver, high Doppler shift, and long-delay compensation. Engineers can configure any of the three platform layers (e.g., GEO/LEO satellite, HAPS, and UAV) concurrently, define base stations and user equipment, incorporate antenna patterns, configure 3D trajectories, and simulate cross-layer handover and mobility. Paired with the P8800S UeSIM UE emulation toolset and EXata network modeling / digital-twin scenario generation, the solution provides engineering teams a single lab environment to validate devices and base stations against realistic, seamless multi-layer 3D NTN coverage — without costly field or on-orbit trials, reducing development and deployment cycles.
