The Leica TPS1200+ is the most
competitive total station ever. It provides the market’s most
accurate reflectorless EDM with the smallest laser dot and measures
distances over 1000 meters. Thanks to the new telescope fitted to all
Leica TPS1200+ models, the user also benefits from the most accurate
measurements to reflectors.
Plus: Range and Accuracy The
best reflectorless EDM performance. Measure inaccessible or hard-to-reach
targets more than 1000 meters away – without reflectors – and in true
PinPoint accuracy. With its combination of range, accuracy, laser dot
size and measurement time, the TPS1200+ represents the market’s best
reflectorless EDM. And thanks to its extended range, there’s no need
for additional instrument setups to reach missing points.
• Reflectorless range 1000 m
• PinPoint accuracy 2 mm
• Laser dot size 2 cm/50 m
Plus: Speed and Productivity One person is all it takes to search, lock,
and measure points – more efficient and faster than any other one-person-total
station in the world. The TPS1200+ works with an improved Automatic
Target Recognition (ATR) sensor that tracks and follows the prism with
more accuracy and reliability than ever before. If lock is interrupted,
then the unmatched PowerSearch sensor quickly relocks onto the prism
with one button press. Measure more points and increase productivity.

Angle and distance measurement (IR-Mode)
Highest accuracy - Longest range
TPS1200+’s precision angle measurement system operates continuously
providing instant horizontal and vertical circle readings that are automatically
corrected for any “out of level” by a centrally located twin-axis compensator.
The coaxial EDM uses an infrared laser, has various measuring modes,
and measures to prisms and reflective tape.The range is excellent –
3 km to a single prism – and the accuracy superb – 1 mm + 1.5 ppm. Resolution
is 0.1 mm.
• Fast, continuous, high-accuracy angle measurements
• Choice of accuracy from 1 to 5 seconds
• No initialization
• Twin-axis compensator
• EDM with standard, fast and tracking modes
• Long range, fast measurements and high accuracy
• Totally reliable
PinPoint - reflectorless EDM (RL-Mode)
Marks the point precisely - Measures directly
PinPoint is the ideal tool for measuring to wall corners, inaccessible
objects, facades, rock faces, roofs and walls inside buildings, in fact
to anything at which it is difficult to set up a reflector. PinPoint’s
tightly bundled laser marks the point exactly with a small red dot.
Measurements are taken instantly and directly (no complex routines measurement).
And with PinPoint you can also take very long distance measurements
to prisms.
• Optional for all TPS1200+
• Two versions: standard range R400 (more than 400m), superior
range R1000 (more than 1000m)
• Very small laser spot,marks the point exactly
• Standard measurement and tracking modes
• Accuracy as high as 2 mm depending on measuring mode,range and
target surface
• Motorized TPS1200+ with PinPoint – the perfect tool for scanning
facades and measuring profiles and cross-sections
Automatic Target Recognition (ATR)
Automatic fine pointing - Uniform measurement accuracy
With ATR, you only need to point roughly with the optical sight and
trigger a measurement; TPS1200+ does the rest fully automatically. The
infrared beam transmitted from the telescope is reflected back by the
prism and analyzed instantly. TPS1200+ moves the telescope, fine points
to the center of the prism and measures. As you don’t need to fine point
or focus, you measure much quicker and more relaxed.
• Optional for motorized TPS1200+
• Fast measurements
• High uniform accuracy independent of operator and light conditions
• Measurements to standard prisms (no need for active target)
• A great aid for all work
• Particularly advantageous for repetition measurements and when
measuring to a large number of points
Automatic Target Tracking (LOCK)
Mass point surveys in record time
Lock mode is part of ATR and enables TPS1200+ to track a moving reflector.
After the initial ATR measurement, TPS1200+ remains “locked” onto the
reflector and follows it as it moves. Measurements can be taken at any
time. As intelligent software predicts the reflector movement, TPS1200+
continues to track even if obstructions cause short interruptions to
the beam. If long interruptions should cause complete loss of lock,
just point quickly again with the optical sight or, even better, use
PowerSearch.
• Part of ATR
• For motorized TPS1200+
• Best with 360° reflector
• Fully automatic
• Eliminates manual operation
• Very fast measurements
• Perfect for mass point surveys
• Use for topo, DTM,details surveys, profiling etc.
PowerSearch (PS)
Finds reflector automatically
PowerSearch finds reflectors within seconds no matter where they are.
With PowerSearch activated, TPS1200+ rotates and sends out a vertical
laser fan. As soon as the fan strikes a prism TPS1200+ stops rotating,
ATR takes over and fine points – all fully automatically. Use PowerSearch
for the first ATR measurement or to find the reflector again if Automatic
Target Tracking loses lock completely. PowerSearch is particularly advantageous
when operating with remote control.
• Optional for motorized TPS1200+ equipped with ATR
• Activated at the touch of a key or automatically, if configured
• Finds standard prisms (no need for active target)
• Saves time, increases productivity
• Highly recommended for fast, efficient one-man remote control
Operate at the reflector
With the RX1250 remote control unit you can control both the TPS1200+
via RadioModem and Radio-Handle and the GPS Smart-Antenna via Bluetooth®
Wireless Technology or cable from the reflector pole.
The control unit has the same display as the TPS1200+, a touch screen,
optionally a colourscreen and a full alphanumeric QWERTY keyboard. Operation
is exactly the same. You can trigger measurements, enter codes, use
routines and programs, collect data from GPS and TPS – whatever you
like.
• Optional for all TPS1200+
• Extend setup to SmartPole
• Best with ATR, PowerSearch and 360° reflector
• Light, rugged, reliable
• Reliable wireless communication via Radio-Handle and Bluetooth®
Wireless Technology
• Perfect one-man survey system
• No need for cables
• Increases efficiency and productivity
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.
