"Global Observer has moved quickly from development and testing toward demonstrating mission-ready, affordable persistence," said Tim Conver, AV chairman and chief executive officer.

"Similar to a satellite, Global Observer is the first system designed to provide a 24/7/365 unblinking eye and continuous communications link over any location on the earth's surface for as long as needed.

"The joint AV and U.S. government team developed Global Observer to meet today's urgent requirements for persistence and to enable the development of much more cost-effective solutions for the future. The speed with which we have achieved this milestone reflects the benefits of an effective government-industry partnership."

Because of its extreme endurance and range, Global Observer can be based out-of-theater, which will further reduce operating costs and local air traffic congestion while significantly reducing risk to operational personnel. AV plans to make Global Observer systems available for procurement and for operation as a turnkey service to provide communications and remote imaging in a manner similar to satellite services, but at a much lower cost.

The hydrogen-powered flight lasted for four hours and reached an altitude of 5,000 feet above sea level over the United States Air Force Flight Test Center at EAFB. This first flight follows the successful battery-powered flight test phase of the demonstration program that took place during the months of August and September.

The flight test team will now systematically expand the altitude and duration of test flights to validate the aircraft's high-altitude, long endurance performance. These flights will include the Air Force's Joint Aerial Layer Network (JALN) Tactical Communications Suite (TCS) payload.

The JALN TCS provides persistent, IP-based aerial communications infrastructure that extends communications from a Global Observer aircraft positioned at 65,000 feet above sea level over a wide area.

The joint operational utility of the Global Observer system will also be assessed during this flight test series for future U.S. Government, civil, and military uses.

Global Observer
With 20 years of experience developing stratospheric, long-endurance unmanned aircraft systems (UAS), AV is developing Global Observer to operate as a "stratospheric geosynchronous satellite system" with regional coverage and minimal signal delay.

Two Global Observer aircraft, each flying for up to a week at a time, will alternate coverage over any area on the earth, providing a seamless, persistent platform for high value missions such as communications relay, remote sensing, long-term surveillance and border patrol.

Offering greater flexibility than a satellite and significantly longer duration than conventional manned and unmanned aircraft, Global Observer is designed to provide critical new capabilities in a reliable and more affordable manner, all while consuming no fossil fuels and emitting no carbon emissions.

In addition to flying above weather and above other conventional airplanes, operation at 55,000 to 65,000 altitude enables sensor payloads on the aircraft to view a significantly larger area on the surface of the earth than conventional, lower flying aircraft.

Equipped with payloads that are readily available today, a two Global Observer system would provide persistent satellite-like coverage over any location on the globe at a fraction of the cost of satellites.

AV received the contract for developing and demonstrating Global Observer as a JCTD program in September 2007. Six U.S. government agencies have provided more than $140 million in funding for the program.
