Commissioning of the TeraNet Optical Ground Station Network
Sascha Schediwy, Aliesha Aden, Benjamin Dix-Matthews +13
TeraNet is a new three-node OGS network that has been established in Western Australia. The network is built to support a broad range of space missions operating between LEO and th…
Optimal design of small aperture optical terminals for free-space links
Alex M. Frost, Benjamin P. Dix-Matthews, Shane M. Walsh +2
We present the generalised design of low-complexity, small aperture optical terminals intended for kilometre-scale, terrestrial, free-space laser links between fixed and dynamic ta…
Free Space Optical Frequency Comparison Over Rapidly Moving Links
Shawn M. P. McSorley, Benjamin P. Dix-Matthews, Alex M. Frost +5
The comparison of optical reference frequency signals over free-space optical links is limited by the relative motion between local and remote sites. For ground to low earth orbit…
The Western Australian Optical Ground Station
Shane Walsh, Alex Frost, William Anderson +8
Free-space communications at optical wavelengths offers the potential for orders-of-magnitude improvement in data rates over conventional radio wavelengths, and this will be needed…
Ultra-stable Free-Space Laser Links for a Global Network of Optical Atomic Clocks
David R. Gozzard, Lewis A. Howard, Benjamin P. Dix-Matthews +3
A global network of optical atomic clocks will enable unprecedented measurement precision in fields including tests of fundamental physics, dark matter searches, geodesy, and navig…
Ultra-wideband free-space optical phase stabilisation
Benjamin P. Dix-Matthews, David R. Gozzard, Skevos F. E. Karpathakis +2
Free-space optical (FSO) communications has the potential to revolutionize wireless communications due to its advantages of inherent security, high-directionality, high available b…
Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network
K. Ackley, V. B. Adya, P. Agrawal +160
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influen…
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…
Stabilized free-space optical frequency transfer
David Gozzard, Sascha Schediwy, Benjamin Stone +2
The transfer of high-precision optical frequency signals over free-space links, particularly between ground stations and satellites, will enable advances in fields ranging from coh…
