Qinertia Post processing

Qinertia is SBG Systems’ in-house post-processing software.
This full-featured software enhances SBG Inertial Navigation Systems performance by post processing inertial data with raw GNSS observables.
Qinertia is very easy to use and ideal for hydrographic survey operations.

Qinertia Post processing

Key Features:

· Tight Coupling INS/GNSS fusion

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

· 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.

. The new 3D view helps you to check your mechanical installation, especially your sensor position, your alignments and lever arms.

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.
