The INS-BU is an industrial-grade GNSS-aided inertial navigation system featuring an advanced single-antenna multi-constellation GNSS receiver from u-blox, as well as three-axis precision accelerometers, gyroscopes and fluxgate magnetometers. It can accept a wide variety of additional aiding data from sources such as Doppler Velocity Logs, odometers, wind sensors and external magnetic compasses.

The sensor provides high-accuracy position, velocity, heading, pitch and roll data for both static and dynamic applications. It can also output AT_ITINS messages for the Cobham Aviator UAV 200 SATCOM terminal, as well as NMEA messages for Pixhawk drone flight controllers.

The INS-BU is ideal for use with a wide range of unmanned systems, including UAVs, UGVs (unmanned ground vehicles) and land vehicles, and USVs (uncrewed surface vessels). It is available in enclosed or OEM board-level versions.
