NTNTracking | 宇宙機搭載型IoTアセットトラッキングおよび全球直接衛星テレマティクスシステム

NTNTrackingは海洋や砂漠で継続的な資産可視化を実現し、超低消費電力の衛星直接IoTプロトコルでコンテナや重機を接続します。

NTNTracking Global Direct-to-Satellite IoT Architecture

Sub-100mW battery-operated sensors communicating with LEO constellations over 3GPP NB-IoT NTN

Central System: 10-Year Battery Cargo Beacon - Sub-100mW 3GPP Rel-17 NB-IoT NTN transceiver

Network Nodes

  • 10-Year Battery Cargo Beacon
  • LEO IoT Nanosatellite Constellation
  • Automated Space-to-Cloud Gateway
  • Global Supply Chain Console

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)
