Cina, A.: Dal GPS al GNSS (Global Navigation Satellite System) per la geomatica. Ed. CELID, 2014. - Educational objectives
- It is expected that the students achieve the objectives relative to Dublin descriptors 1 (content knowledge theoretical and methodological) and 2 (ability to correctly apply the theoretical knowledge) with reference to the content of the course and in particular:
Acquisition of the basic concepts of Geodesy and Mapping, mainly referring to georeferencing problems (datum and coordinates and their conversions). Skill in the reading of maps (traditional and computer-based) deriving quantitative data and other information. Knowledge and application of the main techniques of the terrestrial and satellite surveying and positioning.
Further objectives are the ability to independently manage geodetic-cartographic data with an effective integration of the various sources and visualization tools available, and the acquisition of a correct language for the geological applications of Geomatics. - Prerequisites
- In order to effectively understand and apply the principles and techniques described in the course, a basic knowledge of the following topics is required:
- mathematics, flat and solid geometry and trigonometry;
- basic computer science: cad, excel, office, online research tools;
- basic English language. - Teaching methods
- Lectures on the topics of the course.
Classroom exercises assisted by the teacher on the use of IT methods on the course topics and on the consultation and reading of topographic maps both traditional and computer-based.
Exercises outside on the use of measuring instruments, GNSS and surveying. - Other information
- Due to the applicative character of the module, lecture frequency is advisable
- Learning verification modality
- Single oral exam, lasting about 45 minutes, aimed at verifying that the student is well aware of the topics and methodologies described in the course.
Given the applicative nature of the course, students are advised to present a short report on the practical activities carried out during the course, which will be discussed during the oral examination.
The test will be aimed at ascertaining the following skills (Dublin descriptors 1, 2 3iv, 4):
- knowledge of course contents;
- ability to apply the content;
- autonomy of judgement in the choice and integration of the different methodologies;
- ownership and coherence of the sector language;
- ability to manage a dialectical relationship on the contents of the course.

Elements of Cartography and mapping: Map projections, classification and examples. Deformation modules. The Gauss (Transverse Mercator) projection and its applications. Map of the Italian Cadastre. Representation of the altimetry in maps. Numerical cartography (vectorial and raster).
Practical activities: Reading traditional and numerical maps. Determination of coordinates, heights, sections, profiles and areas.
Satellite positioning and survey: GPS and other GNSS systems. The GPS observables (pseudorange and carrier phase). GNSS instruments. Absolute point positioning with pseudorange. Relative positioning with carrier phase. Static and kinematic surveys. GNSS post-processing: baselines computation, baseline networks adjustment. Real time GNSS with code (DGPS) and carrier phase (RTK). Permanent stations networks: utilisation of network positioning services in post-processing and real time (NDGPS and NRTK).
Terrestrial surveying techniques: measure of angles, distances and height differences. Total stations and three-dimensional survey. Levels and geometric levelling.
