System Components
A GPS surveying system is made up of a number of components that, at first
glance, may seem a bit overwhelming. On the contrary, setup of a GPS system is
not a complicated task. The trick is understanding the purpose of each
component in the system and how they relate to each other. With this
understanding, connectivity of the hardware components, and when and how to
use the software components, becomes logical and straight-forward.
Hardware
A GPS surveying system includes a number of hardware components, each with
a specific function. The Z-Xtreme survey system offers options for many of the
components, each with specific advantages. Choosing the right component will
depend on the users needs and environment in which the system is to be used. In
this section, each of the major components of the Z-Xtreme system is presented.
If options exist for a specific component, each option is discussed.
GPS Receiver
The GPS receiver is the component of the system that processes and stores the
satellite signals. A GPS surveying system requires at least two GPS receivers.
Z-Xtreme Receiver
The Z-Xtreme Survey system is built around the Z-Xtreme dual-frequency GPS
receiver shown in Figure 2.1.
