This research programme is for participation in 3 experiments on space projects that test the predictions of General Relativity (GR) and test foundations of the theory. These are: 1. On GAIA: to determine the bending of light parameter, gamma (=1 in GR) to an accuracy of 1 part in 10^7, and to look for possible angular variations of gamma, which are not predicted by GR but could exist if the foundations of GR are incorrect. 2. Galileo-Galilei: To test the Equivalence Principle, that bodies fall together under gravity, which lies at the foundation of GR. This Italian mission, on which I am a co-investigator, should be able to detect possible violations at a level of 1 part in 10^17 3. CRONOS. Originally an ESA mission of opportunity to determine the gravitational redshift (the slowing down of clocks in a gravitational field) predicted by GR to 1 part in 1000,000 by comparing a high precision clock on board the Russian mission Radioastron with ground based clocks.

该研究计划是为了参与3个实验，这些实验测试了该理论的一般相对论（GR）和测试基础的预测。这些是：1。在盖亚上：要确定光参数的弯曲，伽玛（= 1 in gr）在10^7中的精度为1部分，并寻找可能的角度变化的伽玛的角度变化，如果GR的基础不正确，则无法通过GR预测，但可能存在。 2。Galileo-Galilei：为了测试物体在重力下落在重力下的等效原理，位于Gr的基础上。我是我是共同投资者的意大利任务，应该能够检测到10^17 3. cronos的1个部分的违规行为。最初是ESA的任务，即确定GR在1000,000中预测的重力红移（重力场中的时钟放缓），通过比较俄罗斯任务放射线安斯特朗的高精度时钟与地面时钟。
