AB: The contribution presents GFZ's global and local High-Rate and Low-Latency GPS networks. The global HR/LL network was established, in collaboration with JPL, to support the CHAMP and GRACE POD activities and the radio occultation experiment on both missions. The GFZ sub-network is composed of 13 continuously tracking stations, generating 15-min 1 Hz GPS data files and transmitting them to GFZ every 15 minutes. Eight stations contribute to the Galileo mission preparations. Since early 2003 eight HR sites are streaming GPS data in real time. Three of them take part in the IGS Real-Time Prototype Network. GPS HR/LL network for deformation monitoring is an example of local HR/LL GPS array. This 1 Hz network was installed on Popocapetel volcano end of 1999. For the calibration of satellite altimetry, an autonomous 10 Hz GPS-Buoy was developed by GFZ and is operating in the North Sea. The presentation describes shortly the three systems and discusses issues such as: data performance, real-time data aspects and quality monitoring. Application results from ultra-rapid CHAMP/GRACE orbit processing, radio-occultation routine processing, buoy monitoring and volcano monitoring in geodesy, geophysics and meteorology will be presented.
