/ VN-100

The VN-100 is a small, high performance inertial measurement unit (IMU) and attitude and heading reference system (AHRS). Combining a 3-axis accelerometer, gyro, magnetometer, barometric pressure sensor, and 32-bit processor, the VN-100 provides fast, calibrated IMU data and real-time 3D attitude solutions that are continuous across 360 degrees.

Introduced in 2009, the VN-100 is the first attitude and heading reference system (AHRS) on the market to offer calibrated, high-performance, industrial-grade MEMS sensors and high-quality sensor fusion algorithms in a single surface-mount package. The postage stamp sized VN-100 SMD (Surface Mount Device) is designed to be embedded directly into an electronic assembly.

Sensor overview

Continuous Attitude Solution Across 360° Range of Motion
VectorNav Processing Engine (VPE) 2.0 for disturbance rejection, adaptive filtering, and dynamic filter tuning
Input of external magnetometer or speed measurement (airspeed, GPS)
Hard/soft iron correction
On-board world magnetic and gravitational reference model
Solid-state MEMS inertial sensor
Available in standard (@ 25°C) or fully temperature compensated (-40°C to 85°C)
