BIG B

THE AERIAL BASE OF THE FUTURE

An autonomous stratospheric platform driven by artificial intelligence, maintaining a near-fixed position at 25 km altitude through intelligent exploitation of stratospheric winds — a permanent aerial hub for energy, communications, and drone fleet recharging.

No satellite. No aircraft. Something entirely new —
a quasi-geo-stationary platform powered by 850 kW of solar energy,
operating silently at the edge of space.

The Project

Infrastructure above the clouds.

BIG B is the first commercial quasi-geo-stationary stratospheric platform.

01

Quasi-Geo-Stationary

AI navigation maintains a near-fixed position at 25 km altitude without active propulsion.

02

Massive Solar Power

850 kW of GaAs solar panels power continuous drone fleet recharging.

03

Low Observable

RAM envelope with near-zero radar cross-section for 30+ day stealth missions.

Markets

Four markets. One platform.

🛡️
Defence & ISR
24/7 surveillance, multi-target tracking, stealth persistence.
📡
Telecommunications
4G/5G coverage in dead zones, emergency deployment.
🌎
Environment
GHG tracking, wildfire detection, continuous scientific data.
🚚
Logistics
Aerial drone recharging hub — unlimited operational endurance.
Architecture

A platform engineered for permanence.

Three breakthrough technologies integrated into a single autonomous stratospheric system.

🏵

Lenticular Envelope

An 80-metre RAM-coated lenticular hull providing aerodynamic stability, near-zero radar signature, and structural integrity in the stratospheric environment.

☀️

GaAs Solar Array

850 kW of triple-junction gallium arsenide photovoltaic cells delivering continuous power through 16+ hour solar windows.

🧠

AI Navigation Core

The RL-Wind agent exploits stratospheric jet stream layers to maintain a quasi-geo-stationary position within ±40 km without propulsion.

📱

Winch-Drone System

Four motorised cable winches deploy drones over 10 km vertical ranges, enabling persistent coverage and continuous recharging.

⚖️

Defensible IP

3 patents filed (RAM envelope, winch-drone, RL-Wind). A 4+ year technology barrier against replication.

🌐

Dual-Use Market

Defence, telecoms, environment and logistics — four independent revenue streams from a single deployment.

🏆

No Direct Competitor

Google Loon closed. Airbus Zephyr limited to 75 kg. No platform combines our payload, power, stealth and AI capabilities.
