Bernese Gnss Guide

Bernese GNSS: A Precise Positioning System for Geodetic Applications

Download RINEX data from your receivers and nearby IGS stations.
Obtain precise orbits from CODE (Center for Orbit Determination in Europe) or IGS.
Run preprocessing (screening for cycle slips and outliers).
Compute station coordinates (using either double-difference network solutions or PPP).
Perform quality control by analyzing residuals and repeatability.

4. Advanced Processing Strategies

Why pay for Bernese when GAMIT is free?

The answer lies in rigorous testing and specific algorithms. Bernese is the official processing engine for the International GNSS Service (IGS) and many national reference frame realizations (e.g., Swisstopo, German SAPOS). Its handling of antenna calibrations (absolute vs. relative) and ocean tide loading is considered state-of-the-art.

Hydrostatic delay: Modeled via a priori GPT2w or VMF3 coefficients.
Wet delay: Estimated as a piecewise-linear parameter (usually 1-hour intervals).
Horizontal gradients: Two parameters (NS, EW) to account for asymmetric water vapor distribution.
