The VN-100 Rugged is a miniature, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). Incorporating the latest MEMS sensor technology, the VN-100 combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetic sensors, a barometric pressure sensor as well as a 32-bit processor into a lightweight robust aluminum enclosure, computing and outputting a real-time, drift free 3D orientation solution that is continuous over the complete 360 degrees of motion. The aluminum enclosure package design of the VN-100 Rugged allows for easy integration into your application and provides protection from board stresses and hazards due to harsh environmental conditions.
The MEMS sensors and electronics inside the VN-100 Rugged are protected by a clamshell precision anodized aluminum enclosure. The use of precision CNC milled aluminum parts ensures that the axis alignment provided by our factory calibration process is maintained during installation in its final configuration.
With a size of only 1.30 x 1.41 x 0.35 in., the VN-100 Rugged is the smallest commercially available industrial grade IMU/AHRS. With a mass of only 13 grams, the VN-100 Rugged can be integrated into even the smallest of designs.
Utilizing the latest advancements in MEMS technology, the VN-100 incorporates an assortment of inertial sensors, including a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, and a barometric pressure sensor. The VN-100 has been designed to achieve the highest performance possible by filtering out common error sources, such as sensitivity to supply voltage variations and temperature dependent hysteresis.
To ensure the highest level of accuracy, each VN-100 sensor is individually tested and characterized at room temperature (standard calibration) or over the full operating temperature range (thermal calibration) to determine the bias, sensitivity and cross-axis alignment for each individual component. Calibration coefficients are stored on the device and are fully temperature compensated onboard, in real-time, to ensure high accuracy measurements over the selected operating temperature range.
VectorNav is an industry leader in the development of aerospace grade estimation algorithms for embedded applications. The VN-100 is the only sensor in its class to offer a quaternion based, drift compensated Kalman filter operating with full 32-bit floating point precision at update rates as high as 300 Hz. Unlike other commonly used algorithms, a quaternion based solution ensures reliable operation without the traditional problems associated with gimbal-lock. The high update rates ensure that the sensor reports orientation and angular rates with minimal latency, a crucial requirement for many advanced controls systems.
