Detailed description
Introduction
The Baro-Inertial Attitude and Heading Reference System (BAHRS) incorporates 3x IMU, 3x barometer, 3x magnetometer, and a powerful microcontroller. The device performs sophisticated concurrent Kalman filtering to estimate accurate attitude, heading, vertical speed, and pressure altitude. Triple sensor redundancy enables the device to detect and isolate faulty signals, and continue to operate normaly at the event of a single sensor failure. EULER-NAV BAHRS is designed for use in UAVs operated under SAIL IV and Part 108.

Open Source Software
The BAHRS repository combines firmware source code with tools to re-simulate recordings on a PC, inspect internal signals and evaluate software changes. It also includes log converters, evaluation and sensor-calibration scripts, an NVM configuration utility, and code generators for the runtime environment (RTE) and NVM driver.
