OARS - IMU & GPS Data Logger

"OARS" stands for Orientational Awareness & Reaction Systems.This app was developed as part of the testing process for a larger motion tracking project. The data logger is designed to run in the background on Android OS devices containing an internal GPS, along with a highly accurate inertial measurement unit, or (IMU). Depending on platform and configuration, OARS can record sensor values at a rate over 100hz, or 100 positions per second. All records are timestamped in milliseconds, stored in standard SQL database and CSV structure for use by other programs like Matlab and DBPlot.
