Antenna List Window
The window displays parameters of all GPS antennas which were
calibrated either by NGS or TPS. These parameters are viewable but
not editable. Also the window displays the user-defined antenna
types. You can edit and remove the custom antennas from the antenna
list. The tab displays the following antenna information:
• NGS Name
- the standard NGS (http://www.ngs.noaa.gov/
ANTCAL/) or TPS antenna name. This name is editable only for
the custom antenna type. This name displays in the 'Antenna
number and type' line of the RINEX observation file and in the
corresponding line of the TPS raw data file.
• Name
- the antenna name is used in the software interface. This
name is editable only for the custom antenna type.
• Antenna Calibration
- the type of antenna calibration. The
absolute calibration is a default setting. You can select only the
absolute calibration for the custom antenna. The NGS and TPS
calibration contains the absolute and relative calibrations:
Relative – the antenna offsets and phase center variations are
computed with respect to the AOAD/M_T antenna
Absolute – the recalculated relative calibration that takes into
account the absolute values for AOAD/M_T antenna.
• Radius
- the antenna's radius in millimeters.
• L1 Base Offset (A1)
- the vertical offset measured from ARP
(Antenna Reference Point) to the phase center for the GPS
frequency L1 in millimeters.
• L2 Base Offset (A2)
- the vertical offset measured from ARP
(Antenna Reference Point) to the phase center for GPS frequency
L2 in millimeters.
• L1 Plane Offset (C1)
- the vertical offset measured from the
antenna slant height measure mark (SHMM) to the phase center
for GPS frequency L1 in millimeters.
