gLog

Francesco Meschia, 2013

An open-source acceleration logger.

Based on the OpenLog platform (Atmel ATmega 328P microcontroller with Arduino bootloader) and on the Anaalog Devices ADXL345 triple-axis accelerometer.

Features:

• automatic estimation of the aicraft pitch, roll and yaw axes reference frame at startup, only requires to orient the sensing XZ plane to contain the expected direction of motion
• rotation of all measurements into the aircraft reference frame
• data recording to SD card
• experimental support for automatic launch, zoom and landing recognition for contest timing
