VN-100

IMU / AHRS

Introduction

The VN-100 is a miniature, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). Combining 3-axis accelerometers, gyros, and magnetometers, a barometric pressure sensor and a 32-bit processor, the VN-100 provides high-rate, calibrated IMU data and a real-time 3D attitude solution that is continuous over the complete 360 degrees of motion.

Overview

Introduced in 2009, the VN-100 was the first Attitude and Heading Reference System (AHRS) on the market to offer calibrated, high-performance, industrial grade MEMS sensors and quality sensor fusion algorithms in a single surface mount package. At the size of a postage stamp, the VN-100 SMD (surface mount device) is designed to be directly embedded into [your] electronics assembly. 

To facilitate development and testing, the VN-100 is available in a Rugged “plug and play” version of the VN-100 SMD. Enclosed in a clamshell precision anodized aluminum enclosure, the VN-100 Rugged offers additional protection of the internal inertial sensors and electronics.
