Technology
Lighter-than-air architecture and hybrid propulsion for sustained operations between 1 and 20 km.
Lighter-than-air
The platform is buoyant: it derives lift from displaced air rather than aerodynamic surfaces. Structure and envelope are sized for long-duration stratospheric flight, and the system runs on electrical power suitable for integration with solar and battery sources aboard the vehicle.
Why the stratosphere
Operations take place between 1 and 20 km — above weather and ground interference, yet well below orbital regimes. Air density here is low; the platform is designed for it. Stationkeeping combines buoyancy with hybrid propulsion to hold position over an area of interest for extended periods.
Hybrid propulsion
LHEVIA platforms combine electroaerodynamic (ion-wind) thrust with conventional propellers, all electrically driven. High-voltage electrodes ionise surrounding air; the ions accelerate in the applied field and transfer momentum to neutral air. Propellers add complementary thrust authority for stationkeeping in low-density air.
A dual mission
The vehicle serves as both a connectivity relay and an Earth-observation platform. As an aerial base station it sits far closer to users than satellites, cutting latency for broadband in underserved regions, while its high, persistent vantage supports monitoring of environment, land use, and disaster conditions.
Built around its systems
This is not a cargo airship with a payload bay — the mission systems are integral. Communications and observation equipment are built into the airframe, and the whole vehicle is designed around them. The same platform can be configured for connectivity, Earth observation, or a mixed mission, then operated end to end: launch, ascent to station, position hold, and controlled recovery for refit and reflight.
Configured to the mission
The airframe stays constant; the payload and concept of operations adapt to the task.
