Abstract

With the multiplication of navigation systems (GPS, GALILEO, GLONASS, QZSS, ...) the variety of radio navigation signals to be received increases greatly and involves 8 frequency bands and about 20 different signals. The paper presents an innovative receiver architecture resting on a full flexibility concept, allowing any tracking channel to be allocated to any kind of signal. The resulting software defined receiver stands for a high sensitivity and high accuracy receiver coping with very large dynamic, making the concept adapted to any kind of mission.
