LibrePilot is a Free software unmanned aerial vehicle project for model aircraft aimed at supporting both multi-rotor craft as well as fixed-wing aircraft. Initially founded by David Ankers, Angus Peart and Vassilis Varveropoulos in late 20091, under the name OpenPilot, it was conceived as both a learning tool and to address areas the developers perceived were lacking in other small UAV platforms. In July 2015 OpenPilot, was forked to create LibrePilot. The OpenPilot open source autopilot software could be combined with hardware such as an inertial navigation system board, a main control board, a GPS receiver, and a 2.4 GHz serial communications link with the ground station. The OpenPilot software is released under the GPL version 3 license.

Combined with the sensors, the OpenPilot AHRS contains its own Cortex M3 microcontroller which runs a Kálmán filter. Filtered orientation data and inertial measurements are presented back to the main OpenPilot board using an SPI interface. The OpenPilot AHRS contained the following components: STM32 F1 Onboard (STM32F103C8) 3× ADXRS610 Rate Gyros 1× HMC5843 Magnetometer 1× LIS344ALH 3-Axis Accelerometer ==See also== Open-source robotics ArduCopter Paparazzi Project open-source autopilot PX4 autopilot Slugs (autopilot system)
