GAUGE（GrAnd Unification and Gravity Explorer）任务建议使用一个无阻力的航天器平台，在该平台上附加许多实验。它们旨在解决重力和与其他自然力的统一之间的一些关键问题。等效原理是通过使用经典宏观测试体的高精度测试以及通过冷原子干涉测量使用微观测试体来降低精度。这两个等效原理测试将分别探讨弦膨胀理论和时空涨落的影响。宏观测试体还将用于中程平方反比定律和类轴子自旋耦合搜索。微观测试体提供了扩展测试范围的前景，包括短程平方反比定律和自旋耦合测量，以及寻找由于普朗克尺度的时空涨落而导致的量子退相干的证据。
The GAUGE (GrAnd Unification and Gravity Explorer) mission proposes to use a drag-free spacecraft platform onto which a number of experiments are attached. They are designed to address a number of key issues at the interface between gravity and unification with the other forces of nature. The equivalence principle is to be probed with both a high-precision test using classical macroscopic test bodies, and, to lower precision, using microscopic test bodies via cold-atom interferometry. These two equivalence principle tests will explore string-dilaton theories and the effect of space–time fluctuations respectively. The macroscopic test bodies will also be used for intermediate-range inverse-square law and an axion-like spin-coupling search. The microscopic test bodies offer the prospect of extending the range of tests to also include short-range inverse-square law and spin-coupling measurements as well as looking for evidence of quantum decoherence due to space–time fluctuations at the Planck scale.
