With the development of multiple GNSS systems, the study of adaptive frequency synthesizers in the RF front-end has become increasingly important. In this project, we will develop an implementation of an adaptive frequency synthesizer for the RF front-end of a GNSS multimode navigation receiver to support the use of multiple GNSS systems. The project will design and implement an adaptive frequency synthesizer to dynamically adjust frequency coverage and bandwidth to adapt to changes in various GNSS signals. We will also perform performance testing and experimental verification to evaluate the reliability and practical value of the system.【Keywords】GNSS, RF front-end, adaptive frequency synthesizer, multimode navigation receiver
