OVERVIEW
Maximum performance at the minimum size, weight and price.
To meet the performance demands of today’s sophisticated
UAVs and military aircraft, we have designed the Athena 611 to include navigational
grade IMU, Kalman filter INS/GPS.
Our engineers have designed the Athena 611 with electrical and mechanical
manufacturing processes that meet MIL-SPEC environmental requirements, including
temperature, shock, vibration, EMI, power and humidity to accommodate the
harsh flying environments.
Key benefits
Accurate roll, pitch, heading, in dynamic maneuvers and sustained
turns Full air data measurements including AoA and sideslip Tolerant to GPS outage Optional software module providing Rockwell Collins’ full
suite of advanced and flight proven autopilot, guidance, navigation and mission
management functions
