  • Near Real-Time Telemetry & Alerts
  • Up to 90%+ Data Volume Reduction
  • EU Sovereign Computing Payload

Traditional Ground Processing

  • Unfiltered Downlink: Raw imagery up to 90% cloud-obscured
  • Delayed Alerts: Emergency data waits hours for ground passes
  • High Fees: Expensive RF ground station bandwidth

ABAX On-Orbit Edge Computing

  • Smart Filtering: Filters non-informative pixels in space
  • Near Real-Time: Detects wildfires & vessels on-board instantly
  • Lower Costs: Substantially reduces ground station passes
