Abstract The upcoming Galileo system opens a wide range of new opportunities in the Global Navigation Satellite System (GNSS) market. However, the characteristics of the future signals require the development of new GNSS receivers. This paper presents the devel- oped GNSS receiver architecture (including the Radio Frequency (RF) Front-End and the baseband Hardware (HW) platform), and describes the development of the experimental Global Positioning System (GPS)/Galileo L1/E1 RF Front-End (based on Maxim's MAX2769 chip), capable of being integrated in a space mission, done in the scope of the REAGE project. The results obtained with this new device are presented, focusing on the impact of the Intermediate Frequency (IF) bandwidth on the GNSS signal tracking enabling improvements of more than 50% quality.
