Septentrio introduces post-processing software for its GNSS/INS receivers



Septentrio offers positioning and orientation solutions for the complete mapping workflow, now including Qinertia post-processing software from SBG Systems.

Leuven, Belgium September 27, 2021 - Septentrio, a leader in high-precision GNSS* positioning solutions, starts offering post-processing solutions for its GNSS/INS (Inertial Navigation System) receivers. Land or aerial mapping applications, which do not have access to real-time GNSS corrections, benefit from post-processing software for higher positioning and orientation (heading, pitch and roll) accuracy. With the addition of post-processing, Septentrio GNSS/INS products seamlessly cover the full mapping workflow.  The AsteRx-Pro+ receivers are fully compatible with Qinertia post-processing software, so no data manipulation is required before the post-processing step.

“As a result of our cooperation with SBG Systems, Septentrio’s mapping customers who use GNSS/INS are benefitting from a quicker and more reliable workflow. The intuitive user interface of Qinertia software makes it easy for users to further improve their positioning and orientation accuracy in the post-processing step,” said Danilo Sabatini, product manager at Septentrio. 

In case of GNSS outage or correction link failure, post-processing recovers accuracy for recorded positioning and inertial data. For more information about Septentrio and their GNSS/INS solutions please visit or contact Septentrio.
