VN-100 Surface Mount IMU/AHRS device is a miniature, lightweight, low power, high performance, surface mount Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). VN-100 SMD combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetic sensors, and a barometric pressure sensor along with a 32-bit processor running advanced sensor fusion software – all in a surface mount package the size of a quarter.

Along with providing calibrated sensor measurements, the VN-100 also computes and outputs real-time, drift-free 3D orientation solution that is continuous over the complete 360 degrees of motion. The small size, high performance, and cost-effectiveness of the VN-100 provides unprecedented opportunities for embedded navigation.
