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 com-

plicated task. The trick is understanding the purpose of each component in the sys-

tem 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.

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 compo-

nents, 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.

The GPS receiver is the component of the system that processes and stores the sat-

ellite signals. A GPS surveying system requires at least two GPS receivers.

The Z-Xtreme Survey system is built around the Z-Xtreme dual-frequency GPS

receiver shown in Figure 2.1.
