GNSS data collected with low-cost antennas

The dataset contains GNSS data collected during ten days. To isolate the antenna-related errors from atmospheric propagation ones, an ultra-short baseline was used. A setup consisting of three types of low-cost antennas that support GPS, Galileo, GLONASS, and BeiDou systems measurements and gain > 25 dB was selected for the experiment. In addition, two surveying and geodetic grades Trimble antennas, provide benchmark performance results. The session duration at both mounting points and each measuring day was 16 hours, from 8:00:00 to 24:00:00 UTC. An interval of 5 s and an elevation mask of 0° were adopted.该数据集包含十天内采集的全球导航卫星系统（GNSS）观测数据。为将天线相关误差与大气传播误差分离，实验采用了超短基线布设方案。本次实验选用三款支持GPS、Galileo、GLONASS及BeiDou系统观测、增益大于25 dB的低成本天线作为测试对象。此外，还配备两台Trimble品牌的测量与大地测量级天线，以提供基准性能参考结果。两个安装点位与每个测量日均设置了16小时的观测时段，即协调世界时（UTC）8:00:00至24:00:00。实验采用5秒的采样间隔与0°的高度角截止角设置。
