Qinertia GNSS/INS post-processing software

Intuitive post-processing kinematic for GNSS/INS

Key Features

  • Motion profiles selection to tune sensor behavior to the application dynamics
  • Seamless AsteRx-i3 D Pro+, AsteRx-i3 S Pro+ and AsteRx SBi3 Pro+ data processing
  • Advanced multipath and rejection filters
  • Automatic lever arm and alignment estimation
  • Virtual Base Station (VBS): When you are far from a base station, the VBS computes a virtual network around your project in which centimetric position accuracy is maximized, homogeneous, and robust.



Do you need sub-cm accurate positioning, but you don’t want to set up a real-time base station link? RTK (Real Time Kinematic) accuracy can also be achieved with post-processing, which is known as PPK (Post Processing Kinematic). Often used in mapping and photogrammetry, PPK can be used whenever real-time positioning is not necessary. It can also be used to improve GPS/GNSS data when the real-time base station link is unstable or has malfunctioned. Septentrio PP-SDK offers you the possibility to achieve reliable centimeter-level positioning by post-processing GNSS and base station data.

Full-featured GNSS/INS Post-processing Software

Want to improve your navigation data, to access further analysis, to fix some outages in your trajectory?

Qinertia PPK performs GNSS/INS post-processing with raw GNSS observables. It is offered with AsteRx-i3 D Pro+, AsteRx-i3 S Pro+ and AsteRx SBi3 Pro+  receivers and is ideal for survey and mapping applications. The Septentrio GNSS/INS receiver combined with Qinertia provides a seamless workflow solution from mission data logging (GNSS and IMU) to post-processing. By post-processing GNSS and IMU data, trajectory and orientation accuracy is improved and sensor data such as images can be geotagged. This makes high-accuracy mapping possible even in places where real-time GNSS corrections are not available.
