OVERVIEW
Integrated sensors, flight controls and navigation system.
The Athena 111m offers customers a lower unit cost to accommodate smaller
unmanned systems. Rockwell Collins engineers have designed the Athena 111m
with a fullyintegrated, miniaturized flight control system that combines integrated
INS/GPS and a complete air data suite with robust, multivariable control algorithms.
Designed specifically for high‑performance, unmanned systems,
the Athena 111m leverages our patented Feedback LTi’zation
design technology to provide robust flight control algorithms applicable to
a wide range of vehicles; including, fixed-wing, ducted-fan and rotorcraft
systems.
Key benefits
GPS/INS navigation solution integrated with state-of-the art
Multi-Input/ Multi‑Output flight control laws Control modes that include airspeed, altitude, climb rate,
angle of attack, sideslip, 3-D auto navigation, and auto takeoff/landing Uses highly reliable solid-state sensors, including accelerometers,
rate gyros, magnetometer, air data pressure, AoA and sideslip sensors along
with a differential ready, WAAS-enabled GPS receiver for a full INS/GPS navigation
solution
