OVERVIEW
High-performance, low-cost, integrated INS/GPS/ADAHARS and magnetometer
sensor suite.
Rockwell Collins engineers have integrated solid-state gyros, accelerometers,
magnetometer, GPS receiver and air data pressure transducers into the Athena
111 to meet the demands of any unmanned vehicle application.
The Athena 111 includes a built-in automatic magnetometer calibration
which simplifies the installation process. Our engineers have made use of
Kalman filter algorithms and GPS/magnetometer reference in order to achieve
superior accuracy during dynamic maneuvers. To protect from moisture contamination,
we have equipped the Athena 111 with a sealed enclosure to ensure a long,
troublefree life and performance over full altitude and temperature range.
Key benefits
Provides attitude and heading measurement with static and
dynamic accuracy Includes a differential ready, WAAS‑enabled GPS receiver Full air data measurements
