Study Programmes 2016-2017
GEOG0037-1  
Global Navigation Satellite Systems
Duration :
40h Th, 15h Pr
Number of credits :
Master in geography : geomatics and surveying (120 ECTS)5
Master in space sciences (120 ECTS)5
Lecturer :
René Warnant
Language(s) of instruction :
English language
Organisation and examination :
Teaching in the first semester, review in January
Units courses prerequisite and corequisite :
Prerequisite or corequisite units are presented within each program
Learning unit contents :
The course discusses in details the different concepts on which Global Navigation Satellite Systems (GNSS) are based. The course is divided in 3 parts :
  • Part I : Fundamentals (fundamentals of satellite-based positioning, main GNSS: GPS, GLONASS, Galileo and Beidou, reference systems and frames, time scales, orbits).
  • Part II: GNSS observables and their modeling (Different types of measurements made on GNSS signals, review of the errors sources and their modeling with focus on atmospheric errors and on Space Weather effects).
  • Part III: Positioning techniques and their applications (Different positioning modes: absolute, relative or differential positioning, real-time or post-processing, use of code and/or phase measurements; main modern positioning techniques and their applications with focus on high precision positioning techniques and on phase amibuity resolution).
Learning outcomes of the learning unit :
The main objective of the course is to give students the necessary material in order to be able to use GNSS mainly in the frame of high accuracy applications (centimetre and sub-centimetre) in Geophysics and in Geodesy. Students will be able to assess the reliablility of positions measured by GNSS and to identify the origin of possible problems with the measurements.
Prerequisite knowledge and skills :
Theory of errors (GEOG0626-1)
Planned learning activities and teaching methods :
Mode of delivery (face-to-face ; distance-learning) :
Face-to-face learning
Recommended or required readings :
Lecture notes (in English) are available.
Assessment methods and criteria :
The evaluation consists in an oral exam (with written preparation) on the material seen during theorical lectures.
Work placement(s) :
Organizational remarks :
The course is orgnanised in 3 hour lectures given during the first semester. It is given in English.
