The Astrobotic team has initiated testing of an experimental inertial measurement unit (IMU) loaned from Intel Labs. (IMUs measure a spacecraft's velocity, orientation and gravitational forces.)

The tiny device provides six degree of freedom orientation data, utilizing a bluetooth wireless connection to a host computer. It contains three accelerometers, three gyroscopes, three magnetometers, and a microprocessor. The 9.8 gram IMU runs for six hours on a single charge.
