+Grid

Sovereign, resilient communications backbone

+Grid is the five-layer communications backbone with zero US-dependency: frequency-hopping LoRa, ultra-wideband, software-defined radio, a satellite layer (OneWeb/Eutelsat), and an acoustic infrasound fallback.

Designed to survive jamming and the loss of any single layer — when one path drops, the others hold the recognised air picture.

  • Five independent communication layers
  • Jamming- and EW-resistant by redundancy
  • Zero US-dependency, EU-sovereign
  • Graceful degradation under contested spectrum
