RTI Middleware Powers New General Atomics Aeronautical Systems UAS Ground-Control Station

Successful Predator UAS flight demonstration proves
advanced cockpit-control networking design effectiveness

WASHINGTON DC-August 6, 2007-Real-Time Innovations (RTI), The Real-Time Middleware Experts, announced today that RTI middleware is being used in the General Atomics Aeronautical Systems, Inc. (GA-ASI), Advanced Cockpit Ground Control Station (GCS). A recent flight demonstration on a mission-configured MQ-1 Predator unmanned aircraft system (UAS) validated GA-ASI's major upgrade of the Advanced Cockpit GCS using RTI's networking middleware, which was completed in only 14 months.

"We are proud that General Atomics Aeronautical Systems was able to meet its aggressive schedule with our middleware," said Stan Schneider, chief executive officer at RTI. "This new ground station will greatly increase the effectiveness of GA-ASI's unmanned systems."

The Advanced Cockpit GCS represents state-of-the-art hardware and software technology. It leverages STANAG 4586 architecture, providing interoperability across many UASs including GA-ASI's Predator, Predator B, Sky Warrior Alpha and Sky Warrior Block 0 aircraft systems. The GCS integrates intuitive controls and information displays, touch-screen technology, improved synthetic video, and fused situational-awareness data. The design includes a Common Operating Picture and complete control station for a pilot operator.

RTI middleware is part of the software communications architecture that GA-ASI has implemented for its Advanced Cockpit GCS. The GCS makes use of RTI's publish-subscribe communications model, which allows any system component to subscribe to the incoming aircraft telemetry stream for such parameters as latitude and longitude, pitch, roll, and airspeed parameters.

GA-ASI chose RTI middleware because it quickly provided the needed real-time functionality. For instance, one architectural feature that attracted GA-ASI engineers was RTI's real-time reliability protocol built on the User Datagram Protocol (UDP). Unlike most other messaging products, which use the heavier-weight Transmission Control Protocol (TCP), RTI's approach provides real-time behavior guarantees, such as reliable notification of delivery deadline misses.

RTI middleware also allows GA-ASI to connect multiple workstations, enabling a pilot at one station to work closely with a sensor operator at a different station.
