Or take the Greenland Ice Sheet. As it melts due to warming oceans, the immense weight of ice is removed from the crust. And like a mattress rising after you get out of bed, the solid Earth beneath Greenland is springing upward. This post-glacial rebound, measured by GNSS stations processed through Bernese, is happening at rates of up to 15 mm per year. Those tiny uplifts, aggregated across the ice sheet, become a vital independent check on satellite gravity missions (like GRACE-FO). They tell us how much ice is really being lost: if the ground is rising faster than models predict, the ice must be melting faster than we thought.
Unlike commercial Global Navigation Satellite System (GNSS) software intended for rapid, automated field surveys, the Bernese package is built for scientific exploration. It allows researchers to eliminate minute measurement errors and model physical phenomena across the Earth and its atmosphere with sub-millimeter to centimeter accuracy. The Evolution of Bernese GNSS Software
It is favored by scientists, university researchers, and national mapping agencies for research and education. bernese gnss
The stands as one of the most powerful, high-precision, scientific multi-GNSS data processing engines in global space geodesy. Developed and maintained continuously since the late 1980s by the Astronomical Institute of the University of Bern (AIUB), this package is a foundational pillar for regional and international geodetic initiatives. It handles data from diverse satellite constellations, including GPS, GLONASS, Galileo, and BeiDou, alongside advanced instruments like Satellite Laser Ranging (SLR).
Scientists use BSW to measure the movement of tectonic plates, crustal deformation, and seismic activity. By analyzing years of data, the software helps detect subtle, slow movements of the Earth's crust. 3. Regional Ionosphere and Troposphere Modeling
By incorporating multiple frequencies and constellations, modern iterations (such as version 5.4 and beyond) provide unprecedented geometry, redundancy, and reliability in positioning solutions. Core Capabilities and Processing Modes Just like its home country's famous multi-tool, the
Highly flexible, allowing for both double-difference network solutions and Precise Point Positioning (PPP). It is widely used by:
For a continuous GPS network (e.g., 30 stations over 10 years), Bernese uses : each session (e.g., 24 hours) produces a set of normal equations $\mathbfN_i \mathbfx = \mathbfb_i$. ADDNEQ2 accumulates them:
provides guidance on common errors, such as missing ephemeris files or antenna phase center corrections. Bernese GNSS Software And like a mattress rising after you get
The story of the Bernese GNSS Software begins in the 1980s at the AIUB, under the leadership of Gerhard Beutler. What started as a specialized tool for processing early GPS data has evolved into a global standard for high-precision space geodesy. Its development has been inextricably linked with the International GNSS Service (IGS), where the software and the expertise of AIUB researchers have consistently contributed to defining best practices.
