Ground segment
Stations

- Earthquakes: Earthquakes with magnitude larger than 6 in the vicinity of DORIS sites (less than 500 km) - based on USGS Earthquake notifications
- DORIS internal ties: vectors between different antennas on the same site
- DORIS ties with other IERS techniques: vectors from DORIS to co-located GNSS, SLR or VLBI since 1988.
- Local surveys: some reports online on ITRF website
