Processing of static gnss measurements using trimble business center in the educational process

Geodetic measurements are an integral part of many modern processes, ranging from high-precision engineering projects to the everyday geolocation of photographs. Among the various types of geodetic measurements, those provided by Global Navigation Satellite Systems (GNSS) deserve particular attention. These measurements enable the calculation of the spatial coordinates of the point at which the observations were performed. Typically, the resulting coordinates can be expressed either in geodetic form (latitude, longitude, ellipsoidal height — B, L, H) or in Cartesian form (X, Y, Z). Both types of coordinates are interchangeable and can be converted between each other, provided the parameters of the reference ellipsoid are known. This study focuses on the processing of static GNSS measurements, which play a crucial role in many high-accuracy geodetic applications. For example, such tasks include structural monitoring of engineering facilities such as dams or nuclear power plants. The article presents an accessible method for processing static GNSS measurements that can be effectively integrated into educational curricula. This significantly enhances students’ understanding of working with GNSS receivers. Furthermore, the skills and experience gained from this practice are highly valuable and in demand on the job market, as most modern geospatial tasks require the use of GNSS observations. Additionally, the article describes how to obtain educational GNSS observation data in RINEX format from permanent stations via the website of the European Permanent GNSS Network (EPN).
