DS total stations and the RL-200 rotating laser for levelling
applications.
Topcon said the accuracy of the RL-200 had been improved
from 10 arc seconds to 7, and the range diameter from 800 m
to 1,100 m. The dry cell battery life has gone up from 85 to 100
hours, and the rechargeable battery from 80 to 90 hours.
Most recently, the company introduced the GTS-250 series of
total stations designed to provide field-ready quality and accuracy
with an economical, compact design. The GTS-250 series has a
single-prism range of 2,000 m and features 24,000 point data
storage.
Leighton Davies, business manager for survey products at
Topcon Europe Positioning (TEP), said, “This series provides
the perfect entry-level value choice, and also provides the
construction professional with a dedicated layout solution.”
The desire to save time and money is something that Hilti
has also taken into account. It said with the Hilti POS 150 and
POS 180 robotic total stations, it now only takes one person
positioned at the reflector staff and equipped with a controller to
complete surveying tasks. Thanks to automatic tracking, a second
person at the total station is no longer necessary.
Hilti said it was responding to changes in the industry, including
tight schedules and budgets demanding that construction workers
elements can be flexibly defined without
the need to load additional data. This is
said to allow users to quickly define slopes
and react to design changes in the field.
The company has also introduced a new
line of rugged construction lasers – the
Rugby 800 Series, consisting of the 810,
820, 830 and 840 lasers.
On-board technology includes Smart
Lock, which continuously monitors the
laser plane in real-time and sounds an
alarm if the plane moves out of tolerance,
while Maximum Temperature Stability
technology is siad to provide the highest
accuracy over the entire working range
without drifting.

Topcon has also launched a wide range
of surveying equipment this year, with a focus on increasing
accuracy and efficiency. New products include the PS-AS robotic
total station, a high-precision auto-tracking tool, the motorised

With the Hilti POS 150 robotic total
stations, it now only takes one person
to carry out all the measuring tasks.
The new Trimble MX2 mobile scanner is designed to meet a
growing demand for this type of technology.
StreetMapper’s vehicle-mounted lasers provide 3D mapping
of highways, runways, railways, infrastructure and buildings.
