This course introduces Global Navigation Satellite Systems (GNSS), with a focus on positioning - including hands-on practical experience of collecting and processing data. It also details co-ordinate reference systems and gives an overview of other satellite geodesy techniques.
Outcome:
On completing this unit students will be able to:
■ Describe how GNSS works (including time, orbits, signals, etc)
■ Give an overview of space geodesy capabilities and how they contribute to the ITRF
■ Describe the mathematical models for pseudo-range and carrier phase-based modes of positioning
■ Explain the mathematical models for both single receiver (absolute) positioning and relative positioning
■ Describe and assess GNSS error sources and biases, e.g. atmospheric delays and multipath
■ Select an appropriate working mode for a particular application
■ Discuss current status and future trends of GNSS
■ Process GNSS data using appropriate software and critically analyse the results
