Master tracks in different resolutions during POLAR 2 campaign EPICA_IX@en

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.本数据集通过处理搭载于Polar 6/Polar 5平台的科学设备所配套的全球定位系统（GPS）传感器采集的原始位置数据构建而成，最终得到经过验证的主航迹，该航迹将作为后续科考数据的参考基准。
