Hardware Connectivity

After reading the previous section, you should have an understanding of the function
of each hardware component of an RTK system and how they relate to each other. In
order for the different components to function as a system, they must communicate.
This requires that the components be connected for both communication and power.
Here we will examine the connectivity of the RTK system hardware components.
Since the base system and the rover system have different connectivity requirements,
they will be presented separately. In addition, the rover system is available in two
configurations, backpack configuration and an optional pole-mounted configuration.
Each of these configurations will be presented separately below.

Base System

Below is presented a list of all connections required to make the base RTK system
function.

GPS Receiver - GPS Antenna

The GPS receiver requires an antenna in order to observe the data being transmitted
by the satellites. Therefore, the GPS antenna must be connected to the GPS
receiver. This connection is made through a coaxial cable ranging in length from 3 to
30 meters (Figure 3.1).
