This project aims to develop a new method for laser displacement measurements that will be uniquely suited for use in space. These measurements will enable gravitational measurements of unprecedented accuracy. Missions such as GRACE utilise gravitational observations to provide the distribution of melting polar ice, changes in sea levels, and quantitative estimates of ground water in the world’s food bowls. The technique will also allow space-based gravitational wave detectors far simpler than previous proposals. The improved performance, inherent robustness and drastically reduced complexity will enable new classes of missions that would not otherwise be possible.

该项目旨在开发一种新的激光位移测量方法，该方法将特别适合在空间使用。这些测量将使引力测量达到前所未有的精度。像GRACE这样的任务利用重力观测来提供融化的极地冰的分布，海平面的变化，以及对世界食物碗中地下水的定量估计。该技术还将使天基引力波探测器比以前的提议简单得多。改进的性能、固有的坚固性和大大降低的复杂性将使新类别的任务成为可能，否则是不可能的。
