Flight safety & power redundancy

Failsafes: Loss-of-link recovery initiates automatic return-to-home. Low-energy or supply-loss events trigger return-to-home / controlled landing.
Backup power: Uninterrupted transfer to onboard reserve energy provides ≥30 minutes of airborne operation after ground-power loss. Ground reserve supports tether retrieval.
Navigation: Dual or higher onboard GPS architecture provides navigation redundancy.
