Training for work in Bernese GNSS Software (AIUB, Bern, Switzerland)

In August 2019, the NS RAS acquired the licensed software "Bernese GNSS Software Version 5.2" (Bernese software) from the Astronomical Institute of the University of Bern (AIUB, Switzerland). Bernese software is a multi-platform program for processing measurement data based on Global Navigation Satellite Systems (GNSS), calculating high-precision series of coordinates and velocity vectors. The license for the right to use Bernese software includes the opportunity to undergo a free training for 2 specialists.

GPS laboratory staff lab. S.I. Kuzikov and junior researcher Y.M. Salamatina took a course on installing and using Bernese software at AIUB (Bern, Switzerland) from January 27 to January 31, 2020 http://www.bernese.unibe.ch/course/.

The organizers provided the participants of the courses with a large amount of training material and a manual for Bernese software. To consolidate the lecture material, course participants for 2-3 hours a day were engaged in practical exercises at the terminal session.

At the end of the course, the participants were awarded certificates (Fig. 7.1).
