16.3 ANTEX Converter PHCCNV
16.3.1 General Description
16.3 ANTEX Converter PHCCNV
With the ANTEX converter PHCCNV (”Menu>Conversion>ANTEX to Bernese format”) you are able
to:
• update the Bernese phase center file in case of new antenna calibration values get
available,
• prepare a completely new Bernese phase center eccentricity file (relative or absolute)
from ANTEX,
• convert a relative Bernese phase center eccentricity file (with all included antennas)
to an absolute Bernese phase center eccentricity file,
• merge new or individually calibrated antenna patterns from (relative or absolute)
ANTEX to your existing (relative or absolute) Bernese phase center eccentricity file,
• add patterns of antenna radome combinations that are not included in ANTEX to
the Bernese phase center eccentricity file according to the antenna list in your station
information file,
• update old Bernese phase center eccentricity files containing old satellite antenna
names and no receiver antenna radome codes.
Note that the consideration of radome codes is a must for the ANTEX converter. In addition,
the converter requires the SATELLIT.xxx files made available at the anonymous FTP server
(see Section 4.12). Be sure to use the correct version (*.I01 = relative or*.I05 = absolute),
depending on the desired output phase center eccentricity file type.
The program PHCCNV has three input panels. In the first panel “PHCCNV 1: Input” you
can select input, result and output files. In addition you may choose options concerning
the Bernese input file (see Figure 16.2). General files, in particular the satellite information
file, may be selected in the second panel “PHCCNV 1.1: General Files”. The panel “PHCCNV 2:
ANTEX Conversion” (see Figure 16.2) is specific to the ANTEX file conversion. It provides
options allowing to fill missing phase pattern values up to a specified elevation (or nadir)
angle. Depending on the measurement technique pattern values close to the limiting zenith
(or nadir) angle may be missing. These values may be filled with zeroes or with the value of
the last available zenith (or nadir) angle. In addition, the missing values for ground antennas
may be substituted by the values of the AOAD/M T antenna, the reference antenna in case
of relative antenna patterns. Further description of the options can be found in the online
help or in the examples in Section 16.3.2.
Depending on the input files, the program handles relative or absolute antenna models.
Furthermore the conversion from the relative to the absolute antenna model is possible.
The program checks whether the elevation dependent corrections for the antenna
"AOAD/M_T NONE" numbered with 999999 (second entry in antenna number range)
are zero or not in order to find out whether the input file refers to the relative or the absolute
model. In any case, check the detailed program output carefully in order to verify that
the information for all antennas was properly handled and that the output phase center
eccentricity file is ready for use.
