SBG Systems has released the Horizon IMU, a FOG-based high performance inertial measurement unit (IMU) designed for highly demanding surveying applications such as high-altitude data collection or mobile mapping in dense areas such as urban canyons.

SBG Systems made the announcement at the International LiDAR Mapping Forum (ILMF) in Denver.

The Horizon IMU joins the Ekinox and Apogee IMUs as options for the Navsight Land/Air Solution. The solution consists of a powerful and ready-to-use inertial navigation solution dedicated to surveyors for mobile data collection.

The new Horizon IMU allows customers to bring the Navsight technology to the most demanding environments such as high-altitude surveying and highly dense areas, as well as application where only a single antenna can be used.

The different levels of accuracy enable the solution to meet various application requirements and can be connected to various external equipment such as odometer, lidar and more. The Ekinox and Apogee MEMS-based IMUs address most surveying markets for camera or lidar motion compensation and data geo-referencing.

The Horizon IMU is based on a closed-loop FOG technology which enables ultra-low bias and noise levels. This technology allows robust and consistent performance even in low dynamics survey.

The Navsight solution is easy to install in a vehicle — the sensor alignment and lever arms are automatically estimated and validated. Once connected to the Navsight processing unit, the web interface guides the user to configure the solution.

A 3D view of the vehicle shows the entered parameters so that the user can check the installation. By choosing the vehicle — a plane or a car, for example — the inner algorithms are automatically adjusted to the application.

The Navsight unit also integrates LED indicators for satellite availability, real-time kinematic (RTK) corrections and power.

Full INS/GNSS Post-Processing Software

Completing the Navsight offer, Qinertia, the SBG post-processing software, gives access to offline RTK corrections from more than 7,000 base stations in 164 countries. The software delivers the highest level of accuracy without having to set up a base station. Trajectory and orientation are then greatly improved by processing inertial data and raw GNSS observables in forward and backward directions.

Navsight is ITAR-free. All models are available for order. Ordering information and delivery time are available from SBG Systems representatives and authorized SBG Systems dealers.
