Description

The VN-110 is a Tactical Grade Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). The VN-110 incorporates the latest MEMS sensor technology, combining a 3-axis accelerometer, a 3-axis gyroscope and a 3-axis magnetometer into a compact and rugged package. Along with providing calibrated sensor measurements, the VN-110 also computes and outputs a real-time 3D orientation solution that is continuous over the complete 360 degrees of motion.

 

OVERVIEW

Utilizing the latest advancements in Microelectromechanical systems (MEMS) technology, the VN-110 incorporates a suite of tactical-grade inertial sensors, including a 3-axis accelerometer, 3-axis gyroscope and 3-axis magnetometer. The VN-110 has been designed to achieve the highest performance possible by incorporating VectorNav’s experience producing MEMS-based inertial sensors and proprietary filtering algorithms optimized through a decade of field experience. 

The VN-110 is available in two packaging options: a precision-milled, anodized aluminium enclosure designed to meet DO-160G standards. With dual I/O connectors, the VN-110 offers maximum flexibility for interfacing with external GNSS receivers and IMUs. Alternatively, the VN-110 is available in a miniature, board-mount option delivering tactical-grade IMU performance I compact package bringing the unprecedented capability to SWaP-C constrained applications.
