missionbay_calib2: Magnetometer/accelerometer calibration data.

In animalTrack: Animal track reconstruction for high frequency 2-dimensional (2D) or 3-dimensional (3D) movement data.

Description

Empirical magnetometer/accelerometer calibration data from Mission Bay, CA. These data are a sequence of 2 clockwise yaw rotations, 2 pitch rotations (nose down), and 2 roll rotations (nose facing west, starboard down).

Usage

Details

These data are raw bit values from a three-axis magnetometer and accelerometer. See the $rotation column for when each rotation starts and ends.

Source

These data were recorded by Bill Hagey and Randall Davis.
