International GNSS Service (IGS) GPS Receiver

The GPS receiver in each tracking station within the International GNSS Service (IGS) global network generates raw orbit and tracking data. Among a wide range of scientific and engineering applications and studies, these data help scientists monitor the ionosphere, improving and extending the International Earth Rotation Service (IERS) Terrestrial Reference Frame (ITRF).国际全球导航卫星系统服务（IGS）全球网络中，每个跟踪站内的 GPS 接收器生成原始轨道和跟踪数据。这些数据在众多科学和工程应用与研究领域发挥着重要作用，有助于科学家监测电离层，并改进与扩展国际地球自转服务（IERS）的地球参考框架（ITRF）。
