The position of the base station GNSS antenna can either be determined by the base station GNSS receiver or
can be surveyed in by a chartered surveyor. If the base station GNSS receiver determines its own position,
through position averaging, then any error in the base station receiver will also result in error at the RT. In order
to relate the RT signals to maps, or other items on the world, it is necessary to have a surveyor measure the
position of the GNSS antenna and then tell the base station GNSS receiver what position to use.
For many applications it is not necessary to survey in the base station antenna since an absolute world-
reference is not required. Instead, a local grid can be used.
Using the RT-Base S
The RT-Base S is a self-contained GNSS, radio modem and battery housed in an IP65 rated case. For
instructions on how to use the RT-Base S see the “RT-Base S User Guide”.
The RT-Base S is supplied with a radio modem. This should be connected to the radio connector of the RT user
cable supplied. This cable supplies power to the radio modem as well as sending the differential corrections to
the RT.
