Attitude Heading Reference System with Wi-Fi/Serial and high-cap accumulator, optional with pressure sensors
The ICflyAHRSII is an Atitude Heading Reference System. It continuously monitors its orientation and transmits all orientation related data via Wi-Fi or Serial Port to your target device (e.g. mobile phone / tablet).
Furthermore the ICflyAHRSII can function as an interface between your target device and several avionics like an auto pilot or the ADS-B/FLARM® collision avoidance system.
The professionally calibrated 3-axis gyros, accelerometers and magnetometers lead to precise and reliable atitude and heading information.
The ICflyAHRSII can be upgraded with pressure sensors for static and dynamic pressure, to provide precise altitude and speed information.
