Closing the "digital divide"

HAPS's proximity to the Earth will allow several transmission technologies to operate on the same platform - including TV and radio, broadcast, mobile telephony, VoIP, remote sensing and local GPS.

A large demand exists for broadband and last-mile access from private and public sectors in both developed and developing countries. StratXX's unique stratospheric infrastructure will provide a new source of additional capacity to private and public service providers, broadcasters and telecom operators.

STRATXX's innovative technology offers regions, countries and companies:

•    an easy-to-operate broadband infrastructure
•    convergence support and network compatibility
•    a bridge between "old" and "new" ICT services
•    a sustainable and environmentally friendly solution to the global "digital divide"

Rapid deployment

X-Station's technologies can be deployed, redeployed and upgraded rapidly. They are packaged in a simple modular product range. They can be rolled out step-by-step, as determined by user and market demand.

Competitive advantage

X Station's competitive advantage arises from it complementarities, last mile solution and advanced technology.

STRATXX offers users infrastructure solutions with easy upgrades. Its technology compares favourably with existing communication infrastructures, such as terrestrial wireline, wireless and satellite systems.

Low cost

STRATXX's platforms are expected to be much cheaper than existing and planned infrastructures (terrestrial wire line and wireless and satellite systems).

Environmentally friendly

HAPS are sustainable and environmentally friendly. They use redeployable components and modules. With their low energy exhaust-free propulsion systems, they can be deployed over urban areas. Perfect line-of-sight visibility minimizes electro-smog impact.
Innovative and complementary
Unmanned stratospheric operations offer new services, particularly in the telecommunication, security and surveillance sectors. They are expected to replace or complement tasks currently handled by satellites, aircraft and terrestrial systems.
HAPS research and development began in the late 1950s. Advances in technological and materials have finally reached a stage that can support commercial operations. In addition, technological development of payload equipment ensures HAPS's performance will be sustainable at a high level.

Cutting edge technology

StratXX is well advanced in developing a fixed 21 kilometre altitude X-Station composed of new super-light and super-strength material. The latest technology developed by StratXX is used in its solar power, propulsion, avionics and materials segments.
X-Station will function in all stratospheric climate conditions. Its unique design elements will ensure it overcomes critical technical challenges - such as ascending, descending, thermal power management and fixed point stabilisation.

Realistic roadmap

StratXX will operate and lease its X-Stations to users. It will build a global franchise based on a realistic bundling and regional strategy. Prototype test phases are underway to prove the technology. They will continue until late 2009, with full commercialisation expected by early 2010.
StratXX has developed a patented concept of commercial stratospheric services based on the latest sustainable technology in design, solar power, propulsion, avionics, materials, aerodynamics and other disciplines.

It allows payload equipment to be lifted and maintained in the environment prevailing at high altitudes (low temperature, low air density, high radiation). The concept combines modules that are relatively inexpensive to produce, assemble and operate.
The X-Station is unique due to its innovative design, rapid deployment-redeployment characteristics, upgradeability and modular design. The technology is packaged in a simple, modular and upgradeable product range. By using emission free propulsion systems, there is minimal environmental impact. In addition, its perfect line-of-sight minimizes electro-smog at ground level.

The X-Stations are intended to act as fixed stations in the stratosphere. They can deliver similar capacity to terrestrial systems and have wide-area coverage similar to satellites. X-Stations will extend the range of application of current systems, both complementing and replacing them.
Each X-Station forms a part of the “stratospheric network”. They can be easily recalled to the ground for either replacement or reuse at any time when maintenance or an upgrade is required.
The critical technological aspects of the X-Station include materials, ultra-light design, stability & control, power management and thermal management.

STRATXX’s X-Stations are expected to offer a much more cost effective and cheaper solution than existing satellite- or ground-based networks. Capital expenditure for an X-Station is about EUR20 million, ninety percent of which covers the payload plane.
