The StratoBus Project
Halfway between a drone and a satellite.
This airship-based platform concept is designed for "low cost" missions, and fills the operational gap between satellites and drones (no launcher needed). It can operate in a network and requires only a streamlined land infrastructure. Hovering at an altitude of 20 kilometers, well above air traffic and the jet streams, the StratoBus platform accommodates a 200 kilogram payload, with power consumption of 4 to 5 kW.
It offers regional coverage and endurance of up to one year, depending on where it is based. The design lifetime is five years with annual ground maintenance featuring easy redeployment within a few day.
Multimission platform for dual use applications
Both stationary and easily movable, the StratoBus multimission platform is well suited to both military and civil applications:
|Earth observation and surveillance|
|Homeland security and defense|
|Telecommunications and broadcasting|
|Navigation and environmental monitoring|
|Border and maritime surveillance|
|Boosting GSM network capacity for public events|
|GPS augmentation over areas of dense traffic|
|Internet delivery in zones not covered by terrestrial networks|
An innovative and challenging concept
|Aero dynamical high-altitude airship|
|70 to 100 meters long|
|Filled with an expanding gas in overpressure|
|Hull made of an advanced high-strength, very light material, UV-resistant and with very low permeability|
|Payload located in the best place of the stratosphere to reduce energy consumption to a minimum|
The challenge in this concept is to provide maximum zone endurance while storing enough solar energy during the day to maintain its position at night at any time of the year and for wind speeds of up to 20m/s (90km/h). This makes the platform energy-independent; it will generate power from the Sun using high-efficiency flexible photovoltaic cells coupled with a light amplifier system (Thales Alenia Space patent), and store this power thanks to regenerative fuel cells in the nacelle.
