1 Introduction to the Example Campaign 1.1 Stations in the Example Campaign Data from thirteen European stations of the International GNSS Service (IGS) net- work and from the EUREF Permanent Network (EPN) were selected for the example campaign. They are listed in Table 1.1. The locations of these stations are given in Figure 1.1. Three of the stations support only Global Positioning System (GPS) whereas all other sites provide data from both GPS and its Russian counterpart Globalьna navigacionna sputnikova sistema: Global Navigation Satellite Sys- tem (GLONASS). The observations for these stations are available for four days. Two days in year 2010 (day of year 207 and 208) and two in 2011 (days 205 and 206). In the ter- minal sessions you will analyze the data in order to obtain a velocity ﬁeld based on ﬁnal products from Center for Orbit Determination in Europe (CODE). For eight of these stations, coordinates and velocities are given in the IGb08 refer- ence frame, an IGS–speciﬁc realization of the ITRF2008 (see ${D}/STAT_LOG/ IGb08.snx). , ONSA LAMA JOZ2 GANP WSRT PTBB HERT WTZZ WTZR ZIM2 ZIMM TLSE MATE GPS−only Receiver is tracking Receiver is tracking GPS/GLONASS Station with coordinates/velocities in IGb08 Between these days in 2010 and 2011 the receivers (LAMA, TLSE, WTZR) and the full equipment (WTZZ) have been changed. The receiver type, the antenna type, and the antenna height are also pro- vided in Table 1.1. Notice, that for three antennas (GANP, WTZR, ZIM2) values from an individual calibration are available from the EPN processing. For all other antennas only type–speciﬁc calibration results from the IGS processing (${X}/GEN/IGS08.ATX) are available. More details are provided in Table 1.2. Only in two cases where no calibration of the antenna/radome combination was available (ONSA, WSRT) the calibration values of the antenna without radome were used instead. With one exception (ONSA) even system–speciﬁc calibrations for GPS and GLONASS measurements are available. Figure 1.1: Stations used in example campaign The distances between stations in the network are between 200 and 1000 km. There are two pairs of receivers at one site included in the example dataset: in Zimmerwald, In Kötzting the receivers WTZR the distance between ZIMM and ZIM2 is only 19 m. Page 1
