Bernese is one of the few publicly available software packages capable of computing satellite orbits from scratch. It uses a dynamic orbit model, integrating equations of motion that account for Earth's gravity field (e.g., EGM2008), solar radiation pressure, and third-body perturbations (Moon/Sun). This is essential for Low Earth Orbit (LEO) satellite missions.
The Bernese GNSS Software is a testament to the power of software-defined capability. It transforms commodity hardware into scientific instruments. It turns the noise of the atmosphere into data for weather forecasting. It makes the invisible drift of continents visible.
While the average user navigates their world with a smartphone, unaware of the invisible lattice of signals surrounding them, the infrastructure of modern civilization—maps, time, geodesy—rests on a foundation built and maintained, largely, by a piece of software developed in Bern. It is the unseen ruler by which we measure the world.
Following the 2011 Tohoku earthquake in Japan, researchers used Bernese to compute high-rate (1 Hz to 20 Hz) GNSS displacements. Unlike inertial sensors that saturate during strong shaking, GNSS provides permanent ground displacement. Bernese’s kinematic PPP mode allowed scientists to model the tsunami source within 3 minutes of rupture onset.
Bernese GNSS is used to determine the precise orbits of Low Earth Orbit (LEO) satellites, such as ESA’s Swarm mission or NASA’s GRACE-FO, by processing space-borne GNSS data.
Bernese allows users to choose between different processing modes:
The Bernese GNSS Software remains the gold standard for high-precision geodetic GNSS processing where accuracy and transparency are paramount. Its rigorous double-difference engine, combined with advanced tropospheric and ionospheric models, enables mm-level positioning for global and regional networks. While its learning curve is steep (requiring knowledge of geodesy and Linux scripting), no other open-scientific software matches its fidelity for applications requiring sub-daily displacement tracking or long-term reference frame maintenance.
