6 Z-Surveyor & Z-FX Operation Manual
Performance Specifications
One of the most important functions of the receiver is providing real-time position
solutions with accuracy ranging from centimeter level to 100 meters. Table 1.3
summarizes the positioning modes and expected accuracy.
All accuracies were computed from multiple trials of live satellite data collected in the San Francisco
Bay area with Z-Surveyor receivers and Geodetic III antennas under average multipath conditions.
Receiver Options
Table 1.4 lists the available options. Each option is represented by a letter or number
presented in a certain order. You can verify the installed options by going to the
options table under the System Information (
SYSINFO
) menu through the front panel
of the receiver.
You can also verify the installed options by issuing the following command to the
receiver using an external handheld controller or PC, as described in the Z-Family
Technical Reference Manual:
• $PASHQ,RID
The command will display the options on the external handheld controller or PC. For
example:
$PASHR,RID,UZ,30,UC00,BUEXMFT3JK,0A13*75
