Two nodes. One unjammable network.

The anchor of a timing cluster. Hardware-timestamped Ethernet and a disciplined OCXO reference let it query distant slave nodes and hold sub-nanosecond captures.

• Core computer: Intel NUC 11/12/13 Pro (Mini PC) with an Intel i225-V or i226-V Gigabit Ethernet NIC — crucial for hardware-level sub-nanosecond timestamp clock captures.
• 2.4GHz LoRa RF bridge: FTDI FT232H USB-to-SPI bridge breakout wired directly to an SX1280 breakout module. Connects to the Intel NUC via a standard USB port.
• High-stability reference clock: Leo Bodnar GPS-disciplined OCXO or a dedicated USB-based oven-controlled crystal oscillator module. Feeds a reference clock signal directly into the system to prevent tracking drifts during calculation gaps.
• Antenna: 2.4GHz 12dBi directional sector panel antenna. Extends the master hub's range to query distant slave nodes.
• Storage: Onboard 500GB NVMe M.2 SSD (enterprise-grade high endurance).

The terrestrial edge device. IEEE 1588 hardware timestamping, a secure element for wallet binding and an atmospheric sensor for dynamic delay correction.

• Core computer: Raspberry Pi 5 (8GB). Provides the necessary high-speed RP1 I/O controller and Gigabit Ethernet with IEEE 1588 hardware timestamping capabilities.
• 2.4GHz LoRa transceiver: Waveshare SX1280 2.4G LoRa HAT. Plugs directly onto the RPi5 40-pin GPIO header; features an IPEX antenna connector.
• Antenna: 2.4GHz 6dBi omni-directional colinear antenna (with an SMA-to-IPEX pigtail cable). Provides solid wide-area terrestrial line-of-sight coverage.
• Local storage & speed: Waveshare M.2 NVMe SSD HAT paired with a 128GB NVMe M.2 SSD (e.g. Kingston/Crucial). Do not use MicroSD cards, as constant database logging and P2P synchronisation will rapidly corrupt them.
• Cryptographic identity chip: Microchip ATECC608B TrustPlatform breakout (wired via I2C pins 3 and 5). Securely holds the device private key.
• Atmospheric sensor: Bosch BME280 I2C breakout board. Measures local temperature, pressure and humidity for dynamic timing calculations.
• LTE failover module (optional): Waveshare SIM7600G-H 4G HAT or a simple USB 4G LTE dongle with an integrated SIM slot.
