澳洲地球參考框架技術實施計劃第2.3版探討

On the Australian Terrestrial Reference Frame (ATRF) Technical Implementation Plan 2.3

由於板塊運動、斷層活動等地質作用，地表相對於地心地固坐標系的任何位置都會隨時間變化而移動。為因應全球衛星導航系統（GNSS）的廣泛應用以及不同使用者的需求，澳洲採用了「雙框架系統」。
其中，「澳洲地球參考框架」（Australian Terrestrial Reference Frame, ATRF）為時變（動態）坐標系，「澳洲地心基準」（Geocentric Datum Australia, GDA）則為靜態坐標系。雙框架系統的概念是當前國家地理空間基礎設施的一項有效策略，澳洲的實施經驗對我國具有重要的參考價值。
本文旨在探討ATRF技術實施計劃第2.3版，透過中文翻譯該文件，以檢視其內容並就相關議題進行討論，期能作為我國未來實施之參考。

Due to the movement of tectonic plates, faults, and other geological processes, any given location on the Earth's surface shifts over time relative to the Earth-centered, Earth-fixed coordinate system. To accommodate the widespread use of Global Navigation Satellite Systems (GNSS) and the diverse needs of users, Australia has adopted a dual-frame system.
In this system, the Australian Terrestrial Reference Frame (ATRF) is time-dependent (dynamic), while the Geocentric Datum Australia (GDA) remains static. The dual-frame system is an effective approach within national geospatial infrastructure, and the Australian case provides valuable reference for Taiwan.
This article aims to examine Version 2.3 of the ATRF Technical Implementation Plan by translating the document into Chinese, reviewing its content, and discussing relevant issues, with the goal of providing a reference for future implementation in Taiwan.
