Single station experiments with ASO304 data

Satellite observation is becoming more and more relevant to geodetic VLBI since the Genesis is coming up. The Genesis satellite will carry a VLBI transmitter emitting broadband signals in S, C and X bands. A mode with a PRN code is proposed to enable single station measurements. We explore the potential of such measurement by analyzing real data. In the experiment ASO304, the Australian VGOS telescopes tracked five GPS satellites using their L band capability. We correlate these data with a GNSS-like approach — correlating with local replicas instead of interferometry. We perform systematic analysis on the obtained delays to characterize potential performance and error sources, in preparation for the assessment of single station operation possibility of the Genesis mission.
