重力测量、相对论和全球导航卫星系统
Gravimetry, Relativity, and the Global Navigation Satellite Systems
摘要：
相对论是定位系统的一个组成部分，这是考虑到在今天的实践中，通过应用许多“相对论修正”的计算使用的概念借用伽利略物理学。可以开发一种不同的、完全相对论的范例来操作定位系统。这意味着一些根本性的变化。例如，基本坐标是四倍（具有对称意义，而不是三个空间坐标和一个时间坐标），卫星必须具有交叉链路能力。当然，引力必须被考虑在内，但不是用牛顿理论：引力场是，也只是，时空度规。这意味着定位问题和重力测量问题不能分开。一个最优化理论可以发展，因为它是完全相对论的，不包含任何“相对论修正”。我们建议，所有定位卫星系统都应以这种方式运作。这样做的第一个好处是澄清和简化了理论。我们还期望，最终能够以更高的精度运行定位系统。
英文摘要：
Relativity is an integral part of positioning systems, and this is taken into account in today's practice by applying many "relativistic corrections" to computations performed using concepts borrowed from Galilean physics. A different, fully relativistic paradigm can be developed for operating a positioning system. This implies some fundamental changes. For instance, the basic coordinates are four times (with a symmetric meaning, not three space coordinate and one time coordinate) and the satellites must have cross-link capabilities. Gravitation must, of course, be taken into account, but not using the Newtonian theory: the gravitation field is, and only is, the space-time metric. This implies that the positioning problem and the gravimetry problem can not be separated. An optimization theory can be developed that, because it is fully relativistic, does not contain any "relativistic correction". We suggest that all positioning satellite systems should be operated in this way. The first benefit of doing so would be a clarification and a simplification of the theory. We also expect, at the end, to be able to run the positioning systems with increased accuracy.
