IGEX Station Coordinates

One important objective of IGEX is to produce a set of GLONASS station coordinates consistent with the ITRF.

All IGEX station coordinates are very unconstrained in our processing in contrast to the 7 IGS core stations which are tightly constrained to ITRF96/97. This allows for the estimation of the IGEX stations coordinates in the ITRF frame. Our SINEX file has been produced every week and can be used for that purpose with the following limitations:

• Lack of available information on antenna calibration for many of the GLONASS receivers.
• Uncomplete antenna information for some of the IGEX stations.
• As can be noticed in the coordinates plots there are fortnightly periodic variations due to the lack of ocean loading modeling.
