Course content

This course introduces students with in-depth knowledge and practical skills in satellite geodesy, focusing on GNSS (Global Navigation Satellite Systems) technologies. Candidates will develop a comprehensive understanding of GNSS principles, measurement techniques, error sources, and advanced post-processing methods for quality control. The course emphasizes the practical application of GNSS in geodetic surveys, equipping students to plan, execute, and document complex GNSS-based projects. Additionally, students will explore the use of GNSS in indoor positioning systems and gain proficiency in software tools for data adjustment and analysis.

The Candidate:

• Possesses advanced knowledge of GNSS principles and their applications in satellite geodesy
• Understands various error sources in GNSS measurements and knows how to correct and mitigate these errors to improve accuracy
• Can compute precise positions using both code and phase GNSS techniques, incorporating advanced error correction and post-processing methods
• Is proficient in using GNSS post-processing software for data adjustment, quality control, and reliability analysis
• Can plan, execute, and document complex GNSS-based geodetic surveys, applying both theoretical knowledge and practical skills

The main topics of the course include:

• GNSS measurement principles and technologies
• Determination of coordinates using GNSS
• Error sources in GNSS measurements and their mitigation techniques
• Indoor positioning using GNSS
