The rapidly rotating pulsars known as millisecond pulsars have period stabilities which rival that of the best terrestrial clocks. Observations of many millisecond pulsars spread across the sky should allow detection of the gravitational-wave background - likely to be the first direct detection of gravity waves. It will also enable establishment of a long-term time standard which is independent of and probably superior to that derived from terrestrial clocks. New analysis techniques and establishment of an international observing network will be required. Investigation and application of techniques for overcoming radio interference will be an important part of the project.

被称为毫秒钟的快速旋转的天文钟具有与最好的地球时钟相媲美的周期稳定性。对许多散布在天空中的毫秒级恒星的观测应该可以探测到引力波背景--这可能是第一次直接探测到引力波。它还将使建立一个长期的时间标准，这是独立的，并可能上级从地面时钟派生。将需要新的分析技术和建立一个国际观测网。研究和应用克服无线电干扰的技术将是该项目的一个重要部分。
