Quality-checked, one-second cruise track of the Antarctic Circumnavigation Expedition (ACE) undertaken during the austral summer of 2016/2017.

<strong>Dataset abstract</strong> The Antarctic Circumnavigation Expedition (ACE), undertaken in the austral summer of 2016/2017 recorded the cruise track using two independent geo-location instruments: one using GLobal NAvigation Satellite Systems (GLONASS; hereafter referred to as GLONASS) and another primarily using the Global Positioning System (GPS; hereafter referred to as the Trimble GPS). Daily log files were recorded in real-time from both instruments during the expedition and added to MySQL database tables. Following the expedition, quality-checking work has been undertaken to provide a one-second resolution set of positions for the cruise track, which is presented here. <strong>Dataset contents</strong> ace_cruise_track_1sec_YYYY-MM.csv, data file, comma-separated values ace_cruise_track_trimble_example_deviation_2016-12-24.png, metadata, portable network graphics README.txt, metadata, text file data_file_header.txt, metadata, text file <strong>Dataset license</strong> This quality-checked cruise track dataset from ACE is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/<strong>数据集摘要</strong> 2016/2017年南半球夏季开展的环南极航行科考（Antarctic Circumnavigation Expedition, ACE），采用两套独立地理定位仪器记录航行轨迹：一套采用全球导航卫星系统（GLobal NAvigation Satellite Systems, GLONASS，后文简称GLONASS），另一套主要采用全球定位系统（Global Positioning System, GPS，后文简称Trimble GPS）。科考期间，两套仪器均实时生成每日日志文件并存入MySQL数据库表。科考结束后，研究团队完成质量校验工作，最终生成本数据集收录的、分辨率为1秒的航行轨迹位置数据集。 <strong>数据集内容</strong> ace_cruise_track_1sec_YYYY-MM.csv：逗号分隔值（Comma-Separated Values, CSV）格式数据文件 ace_cruise_track_trimble_example_deviation_2016-12-24.png：可移植网络图形（Portable Network Graphics, PNG）格式元数据文件 README.txt：纯文本格式元数据文件 data_file_header.txt：纯文本格式元数据文件 <strong>数据集许可</strong> 本数据集为ACE科考的经质量校验后的航行轨迹数据集，采用知识共享署名4.0国际许可协议（Creative Commons Attribution 4.0 International License, CC BY 4.0）发布，协议完整文本可通过https://creativecommons.org/licenses/by/4.0/ 查询获取。
