A total station is an electronic/optical
instrument used in modern surveying. It is also used by archaeologists
to record excavations as well as by police, crime scene investigators,
private accident reconstructionists and insurance companies to take
measurements of scenes. The total station is an electronic theodolite
(transit) integrated with an electronic distance meter (EDM) to read
distances from the instrument to a particular point. Some models include
internal electronic data storage to record distance, horizontal angle,
and vertical angle measured, while other models are equipped to write
these measurements to an external data collector, which is a hand-held
computer.
Angles and distances are measured from the total station to points under
survey, and the coordinates (X, Y, and Z or northing, easting and elevation)
of surveyed points relative to the total station position are calculated
using trigonometry and triangulation.
Data can be downloaded from the total station to a computer and application
software used to compute results and generate a map of the surveyed
area.
Some total stations also have a GNSS interface which combines the advantages
of these two technologies (GNSS - line of sight not required between
measured points; Total Station - high precision measurement especially
in the vertical axis compared with GNSS) and reduce the consequences
of each technology's disadvantages (GNSS - poor accuracy in the vertical
axis and lower accuracy without long occupation periods; Total Station
- requires line of sight observations and must be set up over a known
point or with line of sight to 2 or more points with known location).
Most modern total station instruments measure angles by means of electro-optical
scanning of extremely precise digital bar-codes etched on rotating glass
cylinders or discs within the instrument. The best quality total stations
are capable of measuring angles to 0.5 arc-second. Inexpensive "construction
grade" total stations can generally measure angles to 5 or 10 arc-seconds.
Measurement of distance is accomplished with a modulated microwave or
infrared carrier signal, generated by a small solid-state emitter within
the instrument's optical path, and refected by a prism reflector or
the object under survey. The modulation pattern in the returning signal
is read and interpreted by the computer in the total station. The distance
is determined by emitting and receiving multiple frequencies, and determining
the integer number of wavelengths to the target for each frequency.
Most total stations use purpose-built glass Porro prism reflectors for
the EDM signal. A typical total station can measure distances with an
accuracy of about 1.5 millimetres + 2 parts per million over a distance
of up to 1,500 metres.
Reflectorless total stations can measure distances to any object that
is reasonably light in color, to a few hundred meters.
Robotic total stations allow the operator to control the instrument
from a distance via remote control. This eliminates the need for an
assistant staff member as the operator holds the reflector and controls
the total station from the observed point.
