Discover the next level of navigation technology with Xsens Vision Navigator!

Quick Overview

The Vision Navigator is a high-tech navigation unit that uses dual RTK GNSS/INS and vision technology for precise 3D tracking of position, velocity, and orientation, even in challenging outdoor and GNSS-denied environments. Its Visual Inertial Odometry technology ensures that position drift is distance-dependent, rather than time-dependent like in traditional GNSS/INS devices. The unit also features a dual-antenna and built-in IMU that provide reliable heading information, even when moving at low speeds or standing still. In addition to accepting wheel odometry data, it has internal recording memory and a browser-based GUI. The Vision Navigator is fully supported by ROS with resources available on Github.

GNSS Receiver Specifications

The Vision Navigator module includes two multiband GNSS receivers. All four major GNSS constellations (GPS, GLONASS, Galileo and BeiDou) plus QZSS satellites can be received concurrently on both receivers. See the table below. The RTK positioning output is available when combining GNSS correction data and the received satellite signals.

IMU Sensor Specifications

The Vision Navigator incorporates an inertial measurement unit (IMU) that combines a 3-axis gyroscope and 3-axis accelerometer. Their specifications are listed in the table below.

New Technology: Visiual (Intertial) Odometry 

Visual-Inertial odometry (VIO) is the process of estimating the state (pose and velocity) of an agent (e.g., an aerial robot) by using only the input of one or more cameras plus one or more Inertial Measurement Units (IMUs) attached to it. VIO is the only viable alternative to GPS and lidar-based odometry to achieve accurate state estimation.
