On-ice kinematic and static survey data for the evaluation of a new GNSS receiver, Summit Greenland, 2022-08-19 to 2023-04-08

This dataset was created to assess the relative accuracy and precision of a novel, low-cost, low-power global navigation satellite system (GNSS) instrument in comparison to existing commercial GPS/GNSS receivers in an Arctic/ice sheet setting. The new instrument, called an OGRE (On-ice GNSS Research Experimental), was used on several kinematic ice sheet surface survey sessions alongside a Trimble R7 west of Summit Station, Greenland. The OGRE was also tested in a static/stationary configuration for 11 12-hour sessions within the vicinity of the Earthscope SMM4 GNSS base station. Here, we provide minimally processed data from these instrument survey-pairs: data are converted from proprietary binary formats into standard RINEX (Receiver Independent Exchange Format) 2.11 files. The kinematic data is provided at 1 Hz, while the static data provided at 30 seconds. For the kinematic traverses, the antenna reference point (ARP) corrections to the snow surface are also provided.

本数据集旨在评估一款新型低成本低功耗全球导航卫星系统（GNSS）仪器，相较于现有商用GPS/GNSS接收机，在北极/冰盖场景下的相对精度与测量准度。该新型仪器名为OGRE（冰面GNSS研究实验装置，On-ice GNSS Research Experimental），曾在格陵兰萨米特站西侧与Trimble R7接收机配合，开展多次动态冰盖地表测量作业。此外，OGRE还在Earthscope SMM4 GNSS基准站附近，以静态/固定配置完成11次为期12小时的测试。本数据集提供经最小化处理的两组仪器配对测量数据：将专有二进制格式转换为标准RINEX（接收机独立交换格式，Receiver Independent Exchange Format）2.11文件。其中动态数据采样率为1赫兹，静态数据采样率为30秒。针对动态测量航线，还附带了天线参考点（ARP）相对于雪面的校正数据。
