SBG Systems

SBG Systems

SBG Systems supply miniature, high-performance, accurate, inertial measurement and motion sensing solutions.
Their sensors are used in industrial, defence and research projects such as unmanned vehicle control, antenna tracking, camera stabilisation and surveying applications.

SBG provide inertial sensors with innovative Micro-Electrical-Mechanical Systems (MEMS) technology.
Such as Attitude and Heading Reference System (AHRS), Inertial Measurement Unit (IMU) and Inertial Navigation Systems (INS) with embedded GNSS.

This technology, combined with advanced calibration techniques, offers a compact and low-cost solution while maintaining high performance at every level.

Key Features:

·      Tight Coupling INS/GNSS fusion

·      + 7,000 Base Stations always up-to-date

·      Virtual Base Station

·      Open to all Industry Standards

·      Fastest Processing

·      Modern & Intuitive Interface

·      Survey efficiently, everywhere and easily –  Designed with simplicity to help surveyors get the most of their surveys.

RTK Corrections and Virtual Base Stat

Qinertia gives access to up to date, offline RTK corrections from over 7,000 base stations located in 164 countries.

By creating a virtual base station near your project, the software delivers the highest level of accuracy without having to set up your own base station.

Tight Coupling Post-processing

The advanced tight coupling algorithm has been designed by SBG Systems to deliver the highest accuracy and maximise RTK availability.
Trajectory and orientation are greatly improved by processing inertial data and raw GNSS observables in forward and backward directions, especially in GNSS challenging environments (urban valleys, forests and more).

Advanced Quality Indicators

Thanks to advanced quality control indicators such as Standard Deviation, Separations, GNSS Quality feedback and others, Qinertia provides a full understanding of the survey.
With Qinertia, surveyors can quickly identify and solve any issues such as mechanical installations or sensor alignment to keep the survey on track.


Qinertia has been designed to be easily integrated in your production workflow.
Qinertia supports RINEX industry standard, and for better integration, Septentrio, Novatel, and Trimble native binary format.

A very powerful ASCII export feature allows seamless integration with any third-party software.
SBET and Google Earth are also supported for improved integrated operation.
