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-
gether with the receiver and antenna type
and the antenna height. The locations of
these stations are given in Figure 1.1.
Three of these stations (MATE, ONSA, and
VILL) are IGS core sites. This is a set of
about 95 IGS stations representing the real-
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).

Figure 1.1: Stations used in example campaign
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
the use of the Bernese GPS Software.
