NTNDevice Modern Smartphone Satellite Baseband & RF Engine

Dual-mode terrestrial cellular and 3GPP NR-NTN single-die silicon integration

Central System: Integrated Dual-Polarized Antenna - Omnidirectional circular polarization (RHCP/LHCP)

Network Nodes

Integrated Dual-Polarized Antenna
Low-Noise Ultra-Linear RFFE
3GPP Rel-17/18 Baseband SoC
NTN Protocol Stack Micro-Engine

Architectural Protocol Layers

Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
