TL;DR: The Parkes Pulsar Timing Array (PPTA) as mentioned in this paper is an implementation of the PTA concept based on observations with the Parkes 64m radio telescope, which allows investigation of 'global' phenomena such as a background of gravitational waves or instabilities in atomic timescales that produce correlated timing residuals in the pulsars of the array.

TL;DR: The Compact Array Broadband Backend (CABB) as discussed by the authors is an extension of the Australia Telescope Compact Array (ATCA) with 16-fold increase in observing bandwidth, from 2 x 128 MHz to 2 x 2048 MHz, high bit sampling, and addition of 16 zoom windows (each divided into a further 2048 channels) provide major improvements for all ATCA observations.

TL;DR: The Compact Array Broadband Backend (CABB) as mentioned in this paper has been used to improve the performance of the Australia Telescope Compact Array (ATCA) with a 16-fold increase in observing bandwidth, from 2 в 128 to 2 ǫ 2048 MHz.

TL;DR: The Australia SKA Pathfinder (ASKAP) as mentioned in this paper is a high-dynamic-range wide-field-of-view (WFOV) survey instrument that will utilize focal plane phased array feeds on the 36 12m antennas that will compose the array.

TL;DR: As a pathfinder for the SKA, ASKAP will demonstrate field of view enhancement and computing/processing technology as well as the operation of a large-scale radio array in a remote and radio-quiet region of Australia.
