Chapter 2 Setting-Up The Radian IS
2.1.2.2 Typical base setup
An RTK base station setup will typically consist of a standard
wood tripod or fixed height aluminum GPS tripod, Radian IS
receiver, PDL radio/modem, radio antenna mount/cable, and
antenna and radio antenna mounting bracket. The base system
is typically powered by a large external battery (SLA battery)
that powers both the radio and the Radian IS. Typically the base
radio will hook onto the tripod and the base battery will sit on
the ground.

2.1.2.3 Vehicle base setup
Radian IS may be mounted on a vehicle and used as a base.
Typically the Radian IS and the radio antenna may be screwed
onto magnetic mounts attached to the roof of a vehicle. The
Radian IS may be powered through the cigarette lighter in the
vehicle.
While it is convenient to use your Radian IS mounted to a
vehicle for the base station, small movements caused by getting
into and out of the vehicle, as well as wind and terrain
conditions can cause small or very slow movements to occur,
which will translate to an error of equal proportion at the
rover’s location. Only mount your Radian IS on your vehicle if
