Chapter 2 System Components - Thales Z-Max Operation And Application Manual

System Components
In this chapter we will provide an overview of the components that make up the Z-Max
RTK System for Surveying.
The Z-Max RTK Surveying System is made up of a number of modules. If setup is
taken step by step, the process of assembling a system for collecting GPS data is
simple. The trick is in understanding the purpose of each module in the system and
how they connect to each other. With the understanding of how to assemble the
hardware and when to use the Z-Max software applications, performing real-time
surveys becomes logical and straight-forward.
Compared to most RTK Surveying Systems, the Z-Max is unique in two important
ways. First, most of the components of the Z-Max Surveying System are modular;
they attach directly to the GPS Receiver Module without the need for cables. This
greatly simplifies the configuration process. Secondly, in most of the configurations,
the GPS Receiver Module attaches directly to the tripod (in the case RTK Base) or to
the survey pole (in the case of RTK Rover). Keep these concepts in mind as we
explain each of the components.
The major components of an RTK System are as follows:
GPS Receiver and Antenna
The GPS receiver and the GPS antenna are responsible for collecting and
processing GPS signals. There must be at least two receivers, one at the base
and one at the rover. Additional receivers may be used as extra rover receivers.
Data Link
The data link is any data transmission/reception device such as a radio, a cellular
modem, or even a data cable. The data link's job is to transmit and receive data
and corrections. There must be a transmitter at the base and a receiver at the
rover.
