16. Antenna Phase Center Offsets and Variations Note that an individual serial number in ANTEX has to be numeric and in the range of 1 to 999998, otherwise the serial number is set to zero and the converter overwrites the generic entry of this antenna in the output file. Serial numbers can be translated during RINEX import (program RXOBV3) using the station information file (see Section 4.2.3.4). Also note that the selected Bernese phase center eccentricity file must contain the new satellite antenna names. If it is desired to merge a specific antenna to a Bernese phase center eccentricity file with old satellite antenna names, the update step described in Section 16.3.2.1 has to be done first. 16.3.2.6 Conversion of a Relative to an Absolute Bernese Phase Center Eccentricity File Another feature is the conversion of a relative to an absolute phase center eccentricity file. Select an absolute ANTEX file (e.g., I05.ATX) and a relative Bernese input phase center eccentricity file and mark the checkbox “Conversion from relative to absolute PCV” to activate this option. The resulting Bernese phase center file will then contain all antennas from ANTEX as well as all converted antennas from the input Bernese phase center file that are not included in the ANTEX file. The expansion of the Bernese phase center file with missing antenna radome combinations as described in Section 16.3.2.3 is also possible for the conversion. The conversion is performed by adding the absolute pattern of the reference antenna"AOAD/M_T NONE" to the relative patterns of antennas that are not included in ANTEX. The absolute ANTEX file must contain the mentioned reference antenna. In any case, the program checks whether a conversion is allowed. If either the input ANTEX file contains relative patterns or the input Bernese phase center eccentricity file contains absolute patterns the program stops execution with an error message. Similarly, the program stops if the conversion checkbox remains unmarked, but the two input files are of different model type. 16.3.2.7 Handling of Antennas without Radome Code The new version of the converter forces the user to use antenna radome codes for all antennas as recommended by the IGS policy. For antennas read from the input Bernese phase center eccentricity file with blank radome code, this code is replaced by a string ’????’. The user then has to check the output Bernese phase center eccentricity file and insert the correct radome codes. By disabling the option “Consider antennas without radome code”, antennas without radome code are not written to the output file. In any case, check carefully the antenna names in the input Bernese phase center file, insert missing antenna radome codes and assure consistency with the station information file before starting the conversion. After the conversion, check the detailed output of program PHCCNV. It indicates how each individual antenna was handled. If necessary, repeat the procedure. 16.3.3 Routinely Running PHCCNV For permanent network analysis, users of the Bernese GPS Software are advised to download the SATELLIT.I01 resp. SATELLIT.I05 file on a regular basis from http://www. aiub.unibe.ch/download/BSWUSER50/GEN. When using SATELLIT.I01 and in particular Page 340 AIUB
16.4 Estimation of Phase Center Corrections SATELLIT.I05 in routine processing, updating your Bernese phase center eccentricity file in a BPE process becomes indispensable in order to avoid aborting of your processing. The main reason for that is to keep the satellite-specific antenna phase center corrections up to date in your phase center file (e.g., with respect to new satellites), see Section 16.2.5. As a nice side effect of such an update step, receiver antenna calibrations of added antenna/radome combinations get automatically included in your Bernese phase center eccentricity file. This obviously also includes indicated enlargement of your phase center file (after a change of your station information file). It is worth mentioning that the phase center model identifier gets automatically updated, ensuring a proper phase center model declaration in your SINEX results (see Section 16.2.6). For this purpose, the files I01.ATX and I05.ATX are maintained at CODE (in terms of the GPS/GLONASS satellite constellation) and regularly posted to the addresses mentioned above. Both files are consistent to igs 01.atx and igs05 wwww.atx (e.g., igs05 1402.atx), respectively, which are maintained at the IGS CB (in terms of the IGS receiver network). 16.4 Estimation of Phase Center Corrections The Bernese GPS Software provides the possibility to estimate the antenna phase center offsets ∆r as well as the phase center variations ∆φ ′ (α,z) for both, receiver and satellite antennas. The estimation of the parameters can be enabled in panel “GPSEST 5.1: Setup of Parameters and Pre-Elimination 1” and “GPSEST 5.2: Setup of Parameters and Pre-Elimination 2”. All four parameter types are highly correlated and cannot be estimated at the same time. Note that the term ∆φ ′ (α,z) may be modified by an arbitrary constant ∆φ0 that corresponds to a clock offset. When estimating the function ∆φ ′ (α,z) a singularity arises that may be avoided, e.g., by a zero mean condition or by defining ∆φ ′ (α,0) = 0 (as the model is provided by the IGS). 16.4.1 Estimation of Receiver Antenna Model Parameters We refer to [Rothacher et al., 1995a] for details about the setup of a calibration campaign. The receiver antenna calibration is performed in a local network where data from both frequencies can individually be processed. The first problem which has to be solved is how to determine the correct station positions (ground truth). It is, e.g., possible to use the following approach: let us assume that the calibration campaign consists of two sessions (the sessions should be quite long – at least 24 hours) and let us further assume that only two antennas were present. We select one antenna as reference. We want to estimate the antenna phase center variations ∆φ ′ (α,z). Processing the first session (without estimating antenna phase center offsets and/or variations) the resulting relative position of both stations is corrupted by an unknown mean antenna phase center offset ∆r. If we exchange both antennas before the second session, the result of the second session is corrupted by −∆r. The mean position (stemming from processing both sessions together) is correct. Now, it is possible to fix the station positions and to compute the coefficients defining the function ∆φ ′ (α,z). Bernese GPS Software Version 5.0 Page 341
