A Hybrid Architecture for High Sensitivity Standalone and Assisted Galileo/GPS Receivers

O. Otaegui, N. Lucas, G. Rohmer

Abstract:	Acquisition and tracking methodologies for CDMA signals have been studied for several decades. There are multiple proven acquisition schemes such as serial, hybrid and parallel, which can be performed either with correlators (time domain) or FFT engines (frequency domain). However, the extension of GNSS with Galileo and new GPS signals forces a new deep examination of acquisition and unambiguous tracking techniques suitable for very high spreading factors. This paper examines the challenges researchers and development teams are posed to, whereas a hybrid architecture for future L1 GPS and Galileo receivers is presented. Furthermore the complete architecture has been carried to a HW evaluation platform in order to perform reliable tests to asses the proposed architecture.
