OVERVIEW
Integrated INS/GPS/ADAHRS/flight controls.
Today’s UAV and military applications require
highly sophisticated, compact and affordable INS/GPS/ADAHRS/flight controls
integrated solutions. We have designed the Athena 511 to meet these requirements.
With our electrical and mechanical design and manufacturing process,
our Athena 511 meets MIL-SPEC environmental requirements, including temperature,
shock, vibration, EMI, power, and humidity to accommodate the harsh flying
environments. Athena 511 leverages Rockwell Collins’ solid foundation
of performance and hundreds of thousands of hours of operational and in-theater
experience, providing our customers with solutions to enable their UAV systems
the shortest time to market at the lowest life cycle cost.
