Trimble 5600
For relatively small site surveys, CAST operates a Trimble 5600 D200+
Robotic Total Station. This instrument is capable of 2" angular
precision and, in reflectorless mode can measure distances up to 600m
with an accuracy of 3mm +/- 2ppm. With the active prism, the EDM can
measure distances up to 5,500 meters with an accuracy of 2mm +/- 2ppm.
Used for control point placement, site stake-out, micro-topography
surveys and more, the 5600 provides a flexible solution to many
geomatics applications. The instrument may be linked via an integrated
UHF radio to the powered prism pole so that, as the pole moves from
point to point, servo motors swivel the total station's telescope in
both horizontal and vertical angles to stay aligned with the active
prism. Because the data logger is attached to the prism pole, the
operator can control all aspects of the instrument remotely: one person
surveys, even high resolution micro-topography, are feasible and have
been demonstrated many times by researchers at CAST (Microtopographic Analysis of Leetown, Pea Ridge National Military Park, Benton County, Arkansas, Mapping Microtopography at Double Ditch State Historic Site, North Dakota and InVirMet). Both
angle and distance measurements are easily integrated with GPS data
collected from the Trimble 5700/5800 in a
least-squares network adjustment using Trimble's Geomatics Office software.

Green vectors represent measures from the 5600 total station to an active prism pole as part of a micro-topography survey. The orange vectors represent GPS base-lines measured in fast-static mode using the 5700/5800 instruments. The GPS observations were integrated with the total station survey to establish a geodetic reference for the survey.
