22. Data Structure<br />

22.8.18 Receiver Antenna Orientation File<br />

Type: ASCII<br />

Directory: Campaign-specific directory STA.<br />

Extension: AZI<br />

Content: Receiver antenna orientations.<br />

Created by: User-defined.<br />

Used by: <strong>GPS</strong>EST (”Menu>Processing>Parameter estimation”) and <strong>GPS</strong>SIM (”Menu>Service<br />

>Generate simulated observation data”).<br />

Example: Figure 22.45 and ${X}/DOC/EXAMPLE.AZI.<br />

The antenna orientation file specifies the azimuth of the antenna zero-azimuth. Each session<br />

is listed, where any of the antennas was not oriented to the north in order to correctly apply<br />

or estimate phase center patterns. This file is of special use if you have to process antenna<br />

calibration campaigns, where the antennas were oriented differently from session to session.<br />

The file contains receiver and antenna name, antenna number, session number, and the<br />

orientation of the antenna (azimuth in degrees). Note that an entry is only considered<br />

if the specified session number corresponds to the session number given in the header of<br />

the observation file. If no antenna orientation file is specified, a default orientation of all<br />

antennas to the north (azimuth of 0) is assumed.<br />

The receiver name contained in the file is not checked in <strong>Version</strong> <strong>5.0</strong> . You may specify the<br />

antenna name in the field foreseen for the receiver name and set the field foreseen for the<br />

antenna name blank. Note that in this case each entry is separated by two blank lines.<br />
