伽利略卫星星座和对广义相对论的扩展
Galileo satellite constellation and extensions to General Relativity
摘要:
我们考虑的影响,一些已知的广义相对论的扩展,将与伽利略定位系统的观测,并得出结论,测量它们的可能性。我们具体解决的影响存在的宇宙学常数,汤川除了牛顿的潜力,和存在一个额外的,恒定的加速度。我们还考虑了一个广泛的度量理论,这可以通过参数化后牛顿形式主义分类的现象学的影响。
英文摘要:
We consider the impact of some known extensions of General Relativity in observables that will be available with the Galileo positioning systems, and draw conclusions as to the possibility of measuring them. We specifically address the effects of the presence of a cosmological constant, a Yukawa-like addition to the Newtonian potential, and the existence of an extra, constant acceleration. We also consider the phenomenological impact of a broad class of metric theories, which can be classified through the parameterized Post-Newtonian formalism.
