Abstract
This paper describes a novel measurement system for recording baseband I/Q samples of GNSS signals with a very high bandwidth of up to 600 MHz and over a very long time of 8 hours or more. The recording device is a data grabber based on a high-performance digitiser. Together with a high-gain antenna it allows very detailed GNSS signal analysis for both polarisations (RHCP and LHCP). The challenges of using a data grabber instead of a signal analyser are addressed. Test results using a simple sine wave and navigation signals from a Galileo and GPS satellite are presented and compared with results obtained using a signal analyser.
