Performance Specifications

One of the most important functions of the Z-receiver is providing real-time position
solutions with accuracy ranging from centimeter level to 100 meters. Table 1.2
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 receivers and survey grade antennas under average multipath conditions.

Receiver Options

Table 1.3 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 issuing the
following command to the receiver using an external handheld controller or PC, as
described in Z-Family Technical Reference Manual:
•
The command will display the options on an external handheld controller or PC. For
