Commensal image plane transient search methods with the SKAO

Alex Andersson, Dougal Dobbie, Natasha Hurley-Walker +7

This chapter outlines the key, state of the art, techniques required to conduct commensal image plane transient searches. Using significant experience and expertise from conducting…

Limits on Unintended Radio Emission from Geostationary and Geosynchronous Satellites in the SKA-Low Frequency Range

S. J. Tingay, N. Hurley-Walker, K. Ross +3

We search data from the GLEAM-X survey, obtained with the Murchison Widefield Array (MWA) in 2020, for the presence of radio frequency interference from distant Earth-orbiting sate…

Ionospheric Modelling using GPS to Calibrate the MWA. II: Regional ionospheric modelling using GPS and GLONASS to estimate ionospheric gradients

B. S. Arora, J. Morgan, S. M. Ord +18

We estimate spatial gradients in the ionosphere using the Global Positioning System (GPS) and GLONASS (Russian global navigation system) observations, utilising data from multiple…

Characterization of a Low-Frequency Radio Astronomy Prototype Array in Western Australia

A. T. Sutinjo, T. M. Colegate, R. B. Wayth +12

We report characterization results for an engineering prototype of a next-generation low-frequency radio astronomy array. This prototype, which we refer to as the Aperture Array Ve…

Ionospheric modelling using GPS to calibrate the MWA. 1: Comparison of first order ionospheric effects between GPS models and MWA observations

B. S. Arora, J. Morgan, S. M. Ord +56

We compare first order (refractive) ionospheric effects seen by the Murchison Widefield Array (MWA) with the ionosphere as inferred from Global Positioning System (GPS) data. The f…
