The OARS app is a data logger developed to run on Android OS and devices containing an internal GPS ,along with micro-electro-mechanical systems (MEMS) chipset. Specifically the Invensence MPU-6000 or newer. This chip is a highly accurate inertial measurement unit, or (IMU). Contained within this small IMU is a 3-axis Accelerometer, 3-axis Gyro, and 3-axis Magnetometer. Along with a built in processor, it can calculate movements along 9-axis. Depending on platform and app setting, OARS can record sensor values at a rate up to 100hz, or 100 positions per second. GPS data such as Longitude, Latitude, Direction, Speed, and Elevation, are also logged at approximately 1hz, or 1 update per second. ...
