Fondazione LINKS is a non-for-profit Research Centre and is one of the largest private research centers in Italy. The Space and Navigation Technologies Area consists of a team of senior researchers who have developed significant skills in GNSS algorithms design, signal analysis, software radio developments and testing, thanks to a strong background on signal processing, simulation of signals and systems, performance analysis and assessment. The signal processing expertise of the team covers aspects of signal analysis and design, signal processing algorithms to cope with multipath, interference and spoofing, approaches to monitor the quality of the received signals in a digital GNSS receiver, pre- and post-correlation signal processing, carrier phase processing. LINKS researchers have also the necessary facilities to test GNSS devices in controlled environments or in real outdoor scenarios.
