4.10.2 Import to <strong>Bernese</strong><br />

RXMBV3 (”Menu>RINEX>Import RINEX to <strong>Bernese</strong> format>Meteo files”) transforms the RINEX meteo<br />

files into <strong>Bernese</strong> meteo files (description see Section 22.9.3). The RINEX format asks for<br />

one meteo file per site and session, in the <strong>Bernese</strong> format one meteo file per site is required<br />

(only one meteo file per site may be specified in <strong>GPS</strong>EST). Therefore, the program RXMBV3<br />

may concatenate RINEX meteo files from different sessions into one (site-specific) <strong>Bernese</strong><br />

meteo file. Optionally, a “Station information file” (Panel “RXMBV3 2: Station Name Translation”)<br />

may be used for converting the station names from RINEX Meteo file to a well defined<br />

name (section “TYPE 001: RENAMING OF STATIONS”).<br />

4.11 ANTEX Files<br />

4.11.1 Definition<br />

The ANTEX (ANTenna EXchange) format was proposed by M. Rothacher and R. Schmid<br />

at the 2002 IGS Workshop in Ottawa, Canada. It is designed to hold information for ground<br />

antennas as well as for <strong>GNSS</strong> satellite antennas concerning phase center offsets and phase<br />

patterns. The format description of version 1.3 may currently be found at<br />

ftp://ftp.igs.org/igscb/station/general/antex13.txt.<br />

Figure 4.13 shows an example for an ANTEX file.<br />

4.11.2 Import to <strong>Bernese</strong><br />

ANTEX is supported by the <strong>Bernese</strong> <strong>GPS</strong> <strong>Software</strong>. Antenna information in ANTEX format<br />

(as well as in the NGS format) can be converted to the <strong>Bernese</strong> antenna phase center<br />

format (see Section 22.4.4) with the program PHCCNV (”Menu>Conversion>ANTEX to <strong>Bernese</strong> format”).<br />

A detailed description of the program PHCCNV can be found in Section 16.3. No<br />

<strong>Bernese</strong> program is writing antenna phase center information in ANTEX format.<br />

4.12 External Data Sources<br />

4.12.1 CODE Products<br />

The Center for Orbit Determination in Europe (CODE) is one of at present eight IGS<br />

analysis centers. CODE is a joint venture of the Astronomical Institute of the University of<br />

Bern (AIUB), the Swiss Federal Office of Topography (swisstopo), and the German Federal<br />

Office of Cartography and Geodesy (BKG). CODE is located at the AIUB in Bern. The<br />

CODE IGS products are made available on the AIUB anonymous ftp account. Apart from<br />

these IGS products, several other files that are specific to the <strong>Bernese</strong> <strong>GPS</strong> <strong>Software</strong> are<br />

updated regularly and may be downloaded. All filenames are in uppercase and most of the<br />

files are UNIX-compressed. This section describes how to use anonymous ftp to obtain the<br />

CODE products as well as files specific to the <strong>Bernese</strong> <strong>GPS</strong> <strong>Software</strong>.<br />
