Argus One tested with payload KENNEDY SPACE CENTER, Fla., June 4 (UPI) -- Payload testing of the tethered, lighter-than-air Argus One unmanned aerial vehicle has been completed in Nevada by the World Surveillance Group Inc. The UAV is a mid-altitude -- 10,000-20,000 -- stabilized airship being developed to carry sensors, cameras and other electronic systems for surveillance and reconnaissance. WSGI said it and its technical partner, which it didn't identify, began integrating the government-provided, classified payload this year and completed payload and flight tests in Nevada. Testing will continue in Maryland, it said, but few details were provided. "We are pleased with the results from the payload and flight testing of the Argus One in Nevada and look forward to additional testing of the Argus One with classified payloads to illustrate the capabilities of the Argus One UAV to our sponsors," said WSGI President and Chief Executive Officer Glenn D. Estella. We are excited by the successful completion of this next step in the development and commercialization of our Argus One airship and expect to continue to execute our airship related strategic plan. WSGI designs, develops and markets lighter-than-air UAVs for communications and security operations.
