中文摘要 | GPS 衛星定位測量已取代了大部份傳統控制測量,尤其是傳統的一、二、三等三 角測量,更是如此。不但節省了工時,而且亦大幅提昇成果精度。但是,在廣域地區上,定 位精度往往受限於衛星星曆,無法有效提昇。因此,若能精密推算衛星星曆,則對於提昇測 量精度,助益甚巨。另外,正確的選用座標系統,則可使前述高精度定位成果,相得益彰。 本文將對精密星曆及相應之座標系統作深入研析, 俾能在未來應用 GPS 衛星測量技術時, 藉由衛星精密星曆之推算,有效提昇測量成果之精度。 |
英文摘要 | GPS positioning technique has replaced the activities of the traditional survey by theodolite, especially in the traditional first, second, and third order triangulation. It has not only saved workload but also improved the accuracy of survey. However, due to the accuracy of ephemeris, it is very difficult to advance the accuracy of positioning for wide area, especially in its scale and orientation. Therefore, if satellite orbit can be computed correctly, then it is great to advance the accuracy of measurement. On the other hand, if coordinate system is selected correctly, it will improve the accuracy of measurement basically. Hence, coordinate system and precise ephemeris will be discussed deeply in this article. |
