An RTK system works only when the radio link between the Base Station and rovers are line of site. The radio waves
transmitted from the Base Station can be blocked by obstacles such as trees, hills, buildings, etc. In order to get a radio signal
around these obstacles, a repeater can be used to receive and then retransmit an RTK signal. The repeater is placed at a point
where it is in view of both the Base Station and the mobile receiver. The repeater then passes the RTK signal around the
obstacle to the rover and allows RTK guidance. The accuracy of the RTK system is still based on the location differences
between the Base Station GPS Antenna and the rover, so sub-inch accuracy cannot be extended past the 6 mile (9.7 km) limit.
There are two versions of the repeater:
•
A5 Repeater
•
AFLink Repeater
The A5 Repeater can be used with any A5 Base Station. The AFLink Repeater can only be used with the AFLink Base Station
models. The difference between the two is the radio. Though both models of repeaters serve the same purpose, the type of
radio that is installed determines which features are available and how it works in the system. For more information on
Repeaters, see A5 and AFLink Repeaters on page 57.
