Design and Simulation of Multi-Frequency Global Navigation Satellite System Receiver Radio Frequency Front-End

by Viswanatha, Raghunath

Abstract (Summary)
This thesis investigates several design approaches that can be employed in a Multi-frequency GNSS Receiver RF front-end for various applications. With the prospect of Galileo and GPS interoperability in the near future, many new avenues for research into the development of multi-frequency receivers have been opened. This thesis concentrates on the design of the front-end of the receiver with the assumption that the signal processing will be done in software (i.e. for a software defined radio approach). Various methods of sampling data are discussed. The software design tool Ansoft Designer® has been used to implement four design approaches that were investigated for RF front-end implementation. Each of the design approaches work with a subset of all the GPS/Galileo signals thus making that particular design approach suitable for particular applications. The various design approaches have been analyzed using Ansoft Designer® and the results are presented for the four design approaches.
