Millisecond pulsars are remarkably regularly-rotating neutron stars that offer the opportunity to detect gravitational waves via the technique known as pulsar timing. Australia has long been a world leader in the discovery and timing of millisecond pulsars, and the Parkes pulsar timing array is one of three major programmes in the world aimed at making the first direct detection of gravitational waves in any frequency band. This project is designed to capitalise on Australia's position of strength in this field by extending the Parkes Pulsar Timing Array dataset (PPTA) so that it has the best chance of detecting gravitational waves in the nanohertz regime until the SKA pathfinders start to come online in 2017.

毫秒脉冲星是非常有规律地旋转的中子星，它提供了通过脉冲星计时技术探测引力波的机会。长期以来，澳大利亚在毫秒脉冲星的发现和定时方面一直处于世界领先地位，帕克斯脉冲星定时阵列是世界上三个主要项目之一，旨在首次直接探测任何频段的引力波。该项目旨在通过扩展帕克斯脉冲星定时阵列数据集（PPTA）来利用澳大利亚在该领域的优势地位，以便在2017年SKA探路者开始上线之前，它有最大的机会探测到纳赫兹范围内的引力波。
