Thesis :- “Investigations on the Influence of Antenna Characteristics on the GNSS Key Performance Indicators by using Real-Time Measurements”

Working and learning on GNSS antennas and live signal measurements. Tasks involving: 1. Antennas for GNSS application 2. CST & HFSS for antenna simulation 3. Measurements with network analyzer 4. PCB design for antenna boards and their assembly 5. Noise Figure measurements for the active parts of the board 7. Live signal measurements with GNSS antennas 6. Python programming to process GNSS data and visualization

Perform installation, commissioning and servicing of products to fit customer needs. Communicate with suppliers and customers.

The objective of my work is to see the effect of antenna quality on the position triangulation while the correction modes are active. To get an understanding of the antenna qualities effect on the outcome we are using it for, position determination. In my work, i build a measurement setup to test this with a number of GNSS antennas. Ideal antenna and others that have degraded characteristics. Collected data using them, then evaluated the results using python programming.
