Towards Genuine Coexistence: Per-Satellite Emission and Radiation Limits to Protect Radio Astronomy and Geodetic VLBI at 1-14 GHz from Satellite Constellations
Balthasar Indermuehle, Lucia McCallum, Emma van der Wateren +7
Geodetic very long baseline interferometry (VLBI) is a vulnerable application of the radio astronomy service (RAS): it provides the fundamental link between the celestial and terre…
Comprehensive VLBI observations of Galileo satellites with the AuScope array
David Schunck, Lucia McCallum, Jamie McCallum +1
Interest in the topic of geodetic co-location in space and space ties has recently intensified within the geodetic community, particularly following the approval of the European Sp…
The impact of observation losses on IVS-R1/R4 VLBI sessions
Tiege McCarthy, Lucia McCallum
Global VLBI observations, to measure Earth orientation and station positions, are organised into 24-hour sessions. Each session has a bespoke schedule created, optimised for the pa…
An experiment to observe GNSS signals with the Australian VGOS array
Lucia McCallum, David Schunck, Jamie McCallum +1
This paper introduces a new instrument enabling a novel combination of Earth measuring techniques: direct observations with the radio astronomical instruments to satellites of the…
