Subject: New 1 Hz real time station at REDU

A new IGS station has been installed at Redu (Belgium). It is downloaded in real
time to ESOC and the data are available at the IGS data centres in 15 minutes 1
Hz files and hourly and daily 30 second files. It is provisionally connected to
a Rubidium since the station Cesium is being repaired.

Since the beginning of this year the complete ESA/ESOC network is delivering 1
Hz real time data. The stations are: KIRU, KOUR,MALI,MAS1,NNOR,PERT,REDU,VILL.

The station information form is attached below
