Objectives

To know the characteristics of the current GNSS (Global Navigation Satellite Systems), identify its limitations and understand the issues of compatibility and interoperability.

 To have the knowledge necessary to determine positions and velocities from code and phase measurements of the GNSS systems. 

 Identify and understand the problems that can affect the GNSS observations and the ways to overcome them. 

To know the advantages and need for integration of GNSS with other sensors and identify the most appropriate solutions depending on the type of application and the desired positional accuracy.

 

 

Learning outcomes and competences

Understand the principles of satellite positioning.

Implement algorithms to compute coordinates from GNSS observations.

To be able to exploit  GNSS systems in solving problems of geographical location and navigation.

Teaching methods and learning activities

Lectures of theoretical exposition complemented with the individual development of practical works involving field data acquisition and processing and the implementation of a program (in Matlab or any other language) to determine the position of an observer using GPS measurements.

Assessment: distributed, with a theoretical component (final exam) and a practical component that includes the report of practical work and the oral presentations (60%, 40%).

Software

Matlab

Eligibility for exams

The attendance in the tutorial classes is compulsory according to the University of Porto rules.

Calculation formula of final grade

Final examination, report with the practical work and oral presentations on topics related to the program

Formula Evaluation:

FINAL = A + B where: A=0.6*E B=0.4*P E: Written examination (0 to 20), P: Assessment of the report and oral presentations(0 to 20).

Minimum: 50% (6/12) in the written examination and 50% (4/8) in the practical component. The practical component is not subject to appeal. The students who do not obtain a minimum score in the practical component will not have approval.

 

NOTE: Final marks above 16 will only be given after a complementary oral examination.
