双向微波卫星跟踪系统PRARE自1995年5月1日起在ERS-2上连续运行。在全球移动、自主的PRARE地面站网络的帮助下，PRARE空间段在sub-dm频段产生几乎永久的双向pn编码范围和载波移位多普勒测量。亚毫米/秒级别的精度。这些数据被许多国际用户组用于推导更高层次的地球动力学产品，如ERS-2轨道、地面站坐标解、地球重力场参数或电离层数量。介绍了由位于奥伯法芬霍芬的主站、位于斯图加特的监测与系统指挥站和位于波茨坦的校准站组成的PRARE空间段、PRARE地面跟踪网络和PRARE控制段的最新状况和性能，并总结了一些重要的数据流和预处理程序以及相关数据的数量、质量、验证和分发程序。最后，给出了外部校准运动PRARE与激光的一些结果，以及用PRARE进行的专用时间传递实验的结果。
The two-way microwave satellite tracking system PRARE is in continuous operation onboard ERS-2 since May 1, 1995. With the assistance of a global network of mobile, autonomous PRARE ground stations, the PRARE space segment produces nearly permanently two-way pn-coded range and carrier shifted doppler measurements at sub-dm resp. sub-mm/s level of accuracy. These data are used by a number of international user groups to derive higher-level geodynamic products such as ERS-2 orbits, ground station coordinate solutions, Earth gravity field parameters, or ionospheric quantities. The paper describes the up-to-date status and performances of the PRARE space segment, the PRARE ground tracking network and the PRARE control segment consisting of the Master Station in Oberpfaffenhofen, the Monitoring and System Command Station in Stuttgart and the Calibration Station in Potsdam Additionally, some of the important data flow and preprocessing procedures as well as relevant data quantity, quality, validation, and distribution routines are summarized. Finally, some results of external calibration campaigns PRARE vs. laser and of a dedicated time transfer experiment with PRARE are presented.
