OVERVIEW
Superior accuracy during dynamic maneuvers.
Developed for compatibility with both UAV and military applications,
the Rockwell Collins Athena 411 integrates solid-state gyros and accelerometers,
magnetometer, GPS receiver and air data pressure transducers into a single
unit.
We have equipped the Athena 411 with a sealed enclosure to ensure a
long, trouble-free life and performance over full altitude and temperature
range to protect from moisture contamination. Our engineers have tested the
Athena 411 under the stringent military specifications for shock and vibrations.
This high reliability, strap-down system provides attitude and heading measurements
with static and dynamic accuracy superior to traditional spinning mass vertical
and directional gyros.
Key benefits
Accurate roll, pitch, heading in dynamic environments and
sustained turns WAAS-enabled, differential ready GPS Kalman filter algorithms for full INS and attitude solution A tactical, low-cost, integrated INS/GPS/ ADAHRS and flight
controls system Dual airspeed and altitude air data measurement

Athena 411 provides all data for modern Primary Flight Displays (PFDs),
Multi-Function Displays (MFDs), Head-Up Displays (HUDs) and Electronic Flight
Bags (EFBs). The INS/GPS reduces sensor acquisition and installation costs. Solid-state
technology significantly improves MTBF. Autopilot and flight controls optional.
