GPS, Global Navigation Satellite Systems

The course presents basic theories of the functions of Global Navigation Satellite Systems (GNSS, e.g. GPS), such as signal types, codes, carrier wave measurement, satellite configuration requirements, and atmospheric impact. Central components are project planning, choosing appropriate methods and instruments of measurement, measurement strategies, satellite signal analysis, satellite status, and atmospheric conditions. Students carry out measurements in the field using techniques such as static measurement, real time measurement with carrier waves (RTK), code measurement, and the differential method. Measurement data are calculated using baseline processing, session adjustment, network adjustment, and transformation to principal coordinate systems. Students also learn other applications, for example, the collection of measurement data for various purposes such as navigation, GIS (positioning/attribute data), coordinate transformation and detail surveys for cartography databases. The course also covers questions relating to local and global coordinate systems with special focus on projection systems and geodetic data. Control point networks such as national, municipal, and construction site networks are also studied. Examples of financial calculation regarding survey projects are treated through tender estimates. Instruction is in the form of lectures, practical exercises, and lab work.
