Phase synchronisation system receiver module for the Mid-Frequency Square Kilometre Array
Skevos F. E. Karpathakis, Charles T. Gravestock, David R. Gozzard +2
Next generation radio telescopes, such as the Square Kilometre Array (SKA) and Next Generation Very Large Array (ngVLA), require precise microwave frequency reference signals to be…
Methods for coherent optical Doppler orbitography
Benjamin P. Dix-Matthews, Sascha W. Schediwy, David R. Gozzard +4
Doppler orbitography uses the Doppler shift in a transmitted signal to determine the orbital parameters of satellites including range and range-rate (or radial velocity). We descri…
SAT.STFR.FRQ (UWA) Detail Design Report (LOW)
Sascha Schediwy, David Gozzard
The Square Kilometre Array (SKA) project is an international effort to build the world's most sensitive radio telescope operating in the 50 MHz to 14 GHz frequency range. Construct…
The Mid-Frequency Square Kilometre Array Phase Synchronisation System
Sascha Schediwy, David Gozzard, Charles Gravestock +5
This paper describes the technical details and practical implementation of the Mid-Frequency Square Kilometre Array (SKA) phase synchronisation system. Over a four-year period, the…
SAT.STFR.FRQ (UWA) Detail Design Report (MID)
Sascha Schediwy, David Gozzard
The Square Kilometre Array (SKA) project is an international effort to build the world's most sensitive radio telescope operating in the 50 MHz to 14 GHz frequency range. Construct…
Simple Stabilized Radio-Frequency Transfer with Optical Phase Actuation
David Gozzard, Sascha Schediwy, Richard Whitaker +1
We describe and experimentally evaluate a stabilized radio-frequency transfer technique that employs optical phase sensing and optical phase actuation. This technique can be achiev…
Astronomical verification of a stabilized frequency reference transfer system for the Square Kilometre Array
David Gozzard, Sascha Schediwy, Richard Dodson +7
In order to meet its cutting-edge scientific objectives, the Square Kilometre Array (SKA) telescope requires high-precision frequency references to be distributed to each of its an…
