Attitude Just One Portion Of Rockwell Collin's Work On AeroVironment UAS

The Rockwell Collins Athena 411 Inertial Navigation, Global Positioning, Air Data, Attitude, Heading, Reference System (INS/GPS/ADAHRS) has been selected by AeroVironment for their Global Observer.

AeroVironment is developing Global Observer, a liquid hydrogen-powered Unmanned Aircraft System (UAS) that will fly at an altitude of 65,000 feet for as many as seven days. The UAS is being designed for U.S. Special Operations Command as well as for other military and civilian applications.

Developed for UAS and military applications, the Rockwell Collins Athena 411 integrates solid-state gyros and accelerometers, magnetometer, GPS receiver and air data sensors into a single small unit. This highly reliable, strap-down system provides attitude and heading measurements with accuracy that is superior to traditional inertial the Company's ARC-210 radio solution, which offers two-way, multi-mode voice and data communications over a 30 to 512 MHz frequency range. The system also includes embedded Ultra High Frequency (UHF) and Very High Frequency (VHF) anti-jam waveforms and other data link and secure communications features.

AeroVironment is developing and building the Global Observer aircraft over the next three years to demonstrate the ability to operate in the stratosphere for as many as seven days without landing. The program is intended to demonstrate the tactical utility of a hydrogen-powered unmanned aircraft system for global, stratospheric, long-duration missions. A system consisting of two or three aircraft will provide continuous intelligence, surveillance and reconnaissance (ISR) or communications relay over an area of interest. In addition to military applications, the Global Observer is being developed to address critical civilian applications such as hurricane/storm tracking, weather monitoring, wildfire detection, and sustained support for relief operations.
