Bernese GNSS: A Precise Positioning System for Geodetic Applications
: It offers both basic and advanced PPP solutions, allowing for centimeter-level accuracy using precise orbits and clock products Ionosphere Modeling : The software is capable of generating regional ionosphere models (RIM) bernese gnss
The Bernese QIF method, specific to double-difference processing, resolves wide-lane ambiguities first (using $L_1 - L_2$), then narrow-lane ambiguities using fixed wide-lane and ionosphere-free combinations. For networks >100 km, Bernese applies a partial fixing strategy, avoiding ambiguous, low-elevation satellites. Bernese GNSS: A Precise Positioning System for Geodetic
: Bernese uses advanced "double-differencing" techniques to cancel out common errors, providing researchers with the ultimate control over every variable in the satellite signal's journey. A Swiss Army Knife for Satellites A Swiss Army Knife for Satellites The Bernese
The Bernese GNSS software was first developed in the 1980s by the University of Bern, Switzerland. Initially, it was designed to process GPS (Global Positioning System) data, but later versions were extended to handle data from other GNSS systems, such as GLONASS (Russian), Galileo (European), and BeiDou (Chinese). The software has undergone significant improvements over the years, with new features and algorithms being added to enhance its performance and accuracy.
