Abstract :
The new GPS L5 signal with advanced characteristics in the signal structure is dedicated for safety-of-life applications that have strict requirements on accuracy, availability and integrity. To cope with this new signal, GPS receivers need to be upgraded with new signal processing blocks. This paper presents a robust acquisition architecture suitable for the L5 signal. The architecture can be considered as a combination of the Cross Ambiguity Function based; the energy-based; and the multiple channel acquisition methods.
