GPS Navigation Satellite One of the first scientific applications of GPS was to precisely determine the position of fixed ground antennas in order to study the dynamics of the Earth surface. It was soon realised that in order to obtain the best results it would be necessary to compute very precise orbits of the GPS satellites. A number of groups started doing this and, as a result, the first orbits that were precisely obtained using GPS were those of the GPS satellites themselves.
GPS Navigation Satellite systems have become so widespread that they are almost taken for granted. However, the fact that they are so useful is leading to an expansion of available systems. Several countries are working on systems so product selection may become more complicated. To start, one must have a solid understanding of how satellite navigation systems work, as well as the terminology that is commonly used when referring to the technology.
的GPS衛星導航全球定位系統之一的第一科學應用的是要精確地確定，以研究在地球表面的動態固定地面天線的位置。它很快認識到，為瞭獲得最好的效果，有必要計算GPS衛星的非常精確的軌道。一些團體開始這樣做，並且作為結果，被利用GPS精確獲得的第一軌道是那些GPS衛星本身。
GPS衛星導航系統已成為如此普遍，他們幾乎是理所當然的。然而，事實上，他們是如此有用是導致現有系統的擴展。一些國傢正在研究的系統所以產品的選擇會變得更加複雜。首先，我們必須有一個堅實的理解的衛星導航系統是如何工作的，以及涉及到技術時通常使用的術語。
