About
the Sokkia SRX Robotic Total Station |
|
The
SRX from Sokkia is a fully-robotic, fully-tracking and auto-pointing
robotic total station, with on-demand target reacquisition.
Sokkia’s fully-tracking SRX uses the latest robotic technology. Sokkia’s
patented RED-tech EX technology offers the highest precision on all
ranges of measurements. Sokkia’s
flagship Total Station has the latest technology on-board to make
single-operator measuring quick, easy and accurate. The power and
familiarity of a Windows CE operating system is on-board the SRX.
Sokkia’s SRX has Bluetooth
wireless technology for cable-free use, making this single-operator
Total Station even more convenient.
Multiple data interfaces, including USB and Compact Flash, make data in
the field easy to transport back to the office. Saving data is easier
than ever before with the options of USB or compact flash.
Sokkia’s developers didn’t stop
there; they also enhanced the encoder with IACS technology.
Groundbreaking new Independent Angle Calibration System (IACS) provides
extremely reliable angle measurement with unprecedented stability |

Benefits of the SOKKIA SRX Fully Robotic Total Station |
|
The SRX has
many beneficial features which include: Bluetooth® wireless technology for
reliable cable-free communication, the superb new
RED-tech EX
500 meter Reflectorless phase shift distance measuring meter, digital
encoder driven servo's, unique on-demand search technology, auto-pointing
on prisms and reflective sheets, multiple USB ports, a CF card slot for
easy data transfer, a trigger key for fast measuring, a large fully
illuminated keyboard, full color touch screen display and the Windows CE
operating system. There are a number of different versions of the SRX
available with an accuracy varying from 1" to 5" that allow the SRX to be
used in a wide range of positioning applications.
Work with confidence
To work in single-man setup, the surveyor will only work from the prism
side with full confidence. The pole is equipped with a miniature
omni-directional prism, a robust controller, a communication unit and a
rubber bumper to protect the prism from damage should it fall
accidentally. The unique on-demand search technology ensures that
communication between the SRX and the surveyor is guaranteed, loosing
line-of-sight is no longer a problem. You simply pick up the SRX anytime
you want, the instrument doesn't necessarily have to follow. The remote
controller features all software applications needed to do your surveying
job.
The SRX is equipped with the most comprehensive software on-board for any
application that requires a surveyor behind the instrument. The
dramatically improved RED-tech EX
EDM Distance meter featuring its superior phase shift
technology contributes further to optimum performance for the surveyor.
Reflectorless measurements, even in the most difficult situations and
positions, are unsurpassed within the typical Reflectorless working range
between 30cm and 500m. With these features, the SRX is expected to become
a trendsetter for positioning in industrial and monitoring applications.

The power of
Sokkia's RED-tech EX distance meter |
|
The
RED-tech EX is Sokkia's drastically improved Revolutionary Digital
processing Technology: a revolution in the field of measuring distances;
the result of continuing, smart developments by Sokkia's R&D team in
Japan. RED-tech EX, the third generation of RED-Tech distance meters,
offers greater speed, accuracy and range. It undoubtedly sets the trend
for further generations of precision electronic distance meters. Almost
all of Sokkia's total stations are equipped with the RED-tech electronic
distance meters (EDM) which enables them to make accurate distance
measurements.
But what exactly is so revolutionary about RED-tech EX?
The phase-shift and pulse methods are commonly used in the geodesy
field for taking measurements without using reflectors. RED-tech EX,
Sokkia's revolutionary digital signal processing technology, uses a unique
procedure to analyze four light waves at the same time. The on-board
processor continually compares thousands of measurements in real-time with
the recurring data that has been processed. In doing this it checks and
locates wave discrepancies such as interference that cannot be filtered
out (atmospheric conditions) and temporary obstacles (cars, leaves etc).
This means that only the pure, unadulterated actual signal that has been
returned is used for calculating the waves' exact phase shift. This phase
shift ultimately gives the exact correction which enables the optimum
distance measurement value to be calculated. The intelligent RED-tech EX
processor is able to learn how to execute increasingly accurate,
repetitive measurements by itself. By using this combination of digital
processing and phase shift algorithms technology, Sokkia total stations
quite simply achieve the best performance in terms of accuracy,
repeatability and reliability within the target range of 30 cm to 500
meters.
The difference using RED-tech EX)
Pulse EDM's emit a concentrated, short pulse of high density laser light
and a built-in clock measures the "time of flight". The longer the light
travels the better the time difference between emitting and receiving can
be determent. The downside of this technology is encountered when
measuring distances less than 50 meters since the clock simply cannot
measure the time difference accurately enough due to the extremely short
"time of flight". This means that it is not a problem to measure extreme
distances up to 2000 meters for example. Whether or not this is a positive
sales point is open to question since no one wants to measure an object
that far away due to the difficulty of aiming accurately and capturing the
returned signal.
Phase shift does not use a clock so it is easily possible to measure
objects just 30 cm from the EDM. This is a definite advantage compared
with the pulse method. By far the majority of reflectorless measurements
are made to objects within a range of 200 meters; but RED-Tech EX reaches
500 meters just to be absolutely sure. The phase shift measurement spot is
also much smaller then the pulse diameter. This enables very small objects
such as power lines, the corners of buildings, manholes etc. to be
measured even if obstacles such as leaves or fences are in the way. The
most important feature is that the accuracy of phase shift EDM's is
greater than any other type of EDM.
Safety
Phase shift technology has to emit a continuous laser beam and this
has the positive result of producing a continuous stream of data. In order
to achieve accurate results high output power is needed. This is often
regarded as being hazardous, which is true when it contacts the human eye.
However, the human eye has a reflex speed of 0.1 seconds which makes it
safe to use. The alternative EDM's are not visible. These pulse lasers
will also damage eyes over a long period of exposure but because they are
invisible the human eye will not react and so could be damaged. Since the
pulse method uses invisible light, the manufacturers of this type of
equipment embed an extra laser which functions as a laser pointer. The
possibility exists that this laser pointer may not be aligned with the
EDM. If this should be the case, the distance data will be derived from a
different position to the one that the pointer is targeting. This error is
simply impossible with our RED-Tech EX since the EDM laser is used for
both the pointer and distance measurement functions. |
