International DORIS Service

This page gives access to data files and plots of time series of station positions provided by IDS Analysis Centers.

The International DORIS Service is planning to derive combinations of individual DORIS solutions in the future. However, we present only here individual solutions from the following Analysis Centers IGN/ JPL, LEGOS/ CLS and INASAN for weekly and monthly determinations. Should you need any information about those time series, don't hesitate to contact the Analysis Centers (see contacts, below).

The sets of time series available in the table below are:

ign11wd01: weekly positions derived from IGN/JPL ignwd08 sinex series [contact: P. Willis]

stcd and plots updated every week on average (last update)
sinex available at the IDS Data Centers

lca05md01: monthly time series by LEGOS/CLS [contact: L. Soudarin]
description
stcd and plots regularly updated (last update)

lca07wd01: weekly time series by LEGOS/CLS [contact: L. Soudarin]
description
stcd and plots regularly updated (last update)
free-network sinex solutions available at the IDS Data Centers

ina10wd01: weekly positions derived from INASAN inawd07.snx sinex series [contact: S. Kuzin]
description
stcd and plots regularly updated (last update)
sinex available at the IDS Data Centers

 

IGN, INASAN et LEGOS/CLS weekly series are expressed in the ITRF2005 reference frame while LEGOS/CLS monthly series is expressed in ITRF2000. All are given at the epoch of the measurements compared to the same reference position (no velocity removed). The Analysis Centers used their own cumulative solutions (positions and velocities of all DORIS tracking stations) to define the terrestrial reference frame. Weighted rms and linear velocities are not provided by the Analysis Centers but computed independently during this process.
Some information on the events that occured in the IDS stations is available at ftp://ftpsedr.cls.fr/pub/ids/stations/events/station_events.txt.
The description of the STCD format will be found here.

These DORIS time series are freely available for any scientific studies as DS products.
They can be found at the CDDIS and IGN Data Centers.
