The 3.1 firmware series brings major improvements for all High Performance INS products and offer a unified firmware and set of features for EKINOX, APOGEE, NAVSIGHT and QUANTA products.

This 3.1 firmware aims to ease surveyors jobs especially when used with post processing. The datalogger has been improved and refined with a clearer file layout and new modes of operation such as blackbox.

With this release, post processing workflow with Qinertia is further simplified as all the INS settings are automatically read by Qinertia.

In addition, two new motion motion profiles have been added to better support autonomous vehicles such as large trucks and to get the right balance between accuracy and robustness for marine applications.

Finally, algorithms have been refined to deliver outstanding performance in harsh environments. The real time heave behavior and accuracy has also been improved in shallow water conditions.
