I3M Precision Pointing Device
Fast, drift-free pointing data in a portable package.
The I3M (Inertial Measurement & Magnetometer Module) is a product of NetMAX Robotics' continued development and miniaturization of MEMS-based Inertial measurement instrumentation. It is among the smallest and most accurate MEMS inertial measurement units in the world, providing fast dynamic response and drift-free, absolute pointing data to better than 0.1 milliradian in pitch, roll and yaw -- both indoors and outdoors.
An I3M Provides:
- Full 6 Degrees of Freedom measurements plus 3 Axis magnetic sensing.
- Better than 1 milliradian pointing accuracy (+/- 1m error at 1000 meters) when using our supplied calibration C++ software API.
- 16-bit analog to digital coversion of 3 Axis of Acceleration, Rotation, and Earth's Magnetic Field sensing.
- RS232 interface (115 kbaud) and digital control inputs for maximum flexibility.
- Sampling rates and sensor selection of up to 100 sps.
- On-board temperature sensing for calibration over temperature.
- Packaged and OEM versions.
- Current draw of only 186mA.
- Dimensions: 3.0 inch Length (plug is +.25"), 1.25 inch Width, 0.6875 inch Height, 1.3 ounce Weight.
Applications:
- Attitude Estimation.
- Ground Vehicle Navigation.
- Miltary.
- Marine.
- Industrial.
