Master tracks in different resolutions during POLAR 6 campaign ICEBIRD_2019

This dataset was created via processing of raw position data acquired by the GPS sensor for scientific equipment on Polar 6/Polar 5 to receive a validated master track which is used as reference of further expedition data.本数据集通过处理由搭载于极地6号（Polar 6）/极地5号（Polar 5）的科学设备的全球定位系统（GPS）传感器采集的原始位置数据，生成经过验证的主轨迹（validated master track），该轨迹将作为后续考察数据的参考依据。
