Subject: New IGS station THU2

A new station has been established at Thule, Greenland.

The facilities for the existing THU1 station is scheduled
to be demolished during 1999.

The new station THU2 is equipped with an Ashtech Z18
GPS/Glonass receiver and will until further support the IGEX
campaign.

Data became online  at BKG from 11-NOV-1998 (DOY 315).
A subset of data covering DOY296 - 307 is being prepared
and will be sent to BKG.

I have attached the station log for THU2 below.

Kind regards,

Finn Bo Madsen
