SBG Systems has launched Horizon, a high end FOG-based IMU to top its NavSight navigation unit range.

Released at the International LiDAR Mapping Forum (ILMF) in Denver on January 29, the Horizon is a high performance Fiber Optic Gyro (FOG)-based inertial measurement unit, taking its place above the Ekinox and Apogee IMUs in the NavSight product line.

According to SBG, the Micro-Electro-Mechanical System (MEMS)-based Ekinox and Apogee are aimed at most applications of camera and LiDAR motion compensation and geo-referencing, while the Horizon is aimed at more demanding applications.

The company cites high-altitude surveys, scanning of highly dense areas and applications limited to a single antenna as ideal use cases for this unit.

SBG claims that the closed-loop FOG architecture delivers very low bias and noise levels well-suited to low-dynamics survey applications, automatic sensor and lever arms alignment estimation and validation, and offline RTK corrections via Qinertia, their offline INS/GNSS post-processing suite.
