1. Introduction to the Example Campaign

Data fr om eight European stations of the

IGS Network are selected for the example

campaign. They are listed in Table 1.1 to-

ization of the reference frame (IGS 00: IGS

realization of the ITRF 2000).

Furtherm ore, two stations (FFMJ and

ZIMJ) are equipped with GNSS receivers

tracking GPS and GLONASS satellites. The

receiver antennas of only two sites (ONSA

and PTBB) are equ ipp ed with radomes (type OSOD resp. SNOW).

The receivers used at the stations BRUS and PTBB are conn ected to H-Maser clocks. The

receiver type ASHTECH Z-XII3T was developed for time and frequency applications.

The distances between neighboring stations are between 300 and 1200 km. Two GPS re-

ceivers in Zimmerwald are included into the example (ZIMM and ZIMJ, d istance 14 m).

The observations for these stations are available for four days . Two days in year 2002 (day

of year 143 and 144) and two in 2003 (days 138 and 139). In these terminal sessions you

will analyze the data in order to obtain a velocity field based on IGS final products.

The data belonging to this example campaign are included in the distribution. Therefore,

you may also use this document to repeat the generation of the solution at home to exercise
