For construction professionals this is extremely beneficial, as finding out something may have been installed incorrectly early in the construction process eliminates the extra costs of time and resources. This can also avoid any negative reputational impacts that mistakes and additional work may bring. Without the GTL, scanning and analysing data can take days.
However, with the technology, the process can be done in a matter of hours. An engineer can go out to the field in the morning to scan the latest installed elements, analyse the scan data and then be back on site before lunch with a list of changes that may have been identified. In the past, this was not possible because of the time taken to complete the scanning and analysing process.
The practicality of having just one instrument should also not be underestimated. Usually, to register scan data, engineers would require a robotic or manual total station to coordinate scan targets, with these then scanned with the laser scanner then identified within a processing software package to register the point cloud.
However, with a combined unit such as the GTL, engineers no longer need to set up two different instruments in the same location. Instead, it can all be done in one swift movement, potentially halving the amount of time spent on site. Although there are different technology combinations available on the market which may be cheaper, the overall cost savings for projects have still proved significant when a combined device is used.
Despite the powerful technology the GTL contains, the device weighs only 7kg and fits into one case. As a result, it is easy to carry around site, transport, set up and operate.
This ease of transportation acts as a time-saver as energy is not wasted stopping and starting when carrying heavy materials. Instead, professionals can swiftly set up once they have arrived on site. The surveying profession has come a long way since its origins in ancient Egypt, with technology and digitalisation allowing the industry to continually improve its accuracy, efficiency and speed.
The future looks bright, with many more professionals recognising the benefits that robotic total stations bring. Businesses investing in this technology are saving time, money and resources thanks to innovations like the GTL, which are capable of much more than the average total station.

Home » Reflectorless Revolution. Reflectorless Revolution March 1, What is the principle of total station? Reflectorless total stations can measure distances to any object that is reasonably light in color, to a few hundred meters. Principle: Given the co-ordinate of the instrument position and bearing of a backward station the co-ordinates of any other point can be computed.
How much is a total station? How accurate is a total station? A typical total station can measure distances up to 1, meters 4, ft with an accuracy of about 1. Reflectorless total stations can measure distances to any object that is reasonably light in color, up to a few hundred meters. How many types of total stations are there? Two types are available, One is basic like 4 Arrows with basic keys and Full set of Alpha-Numeric is the another one.
What is the difference between a theodolite and total station? A theodolite needs two people to measure and align the angles. A total station incorporates a theodolites functions into it's programming, measuring angles and using an electronic distance meter. Total stations are usually superior to theodolites given their digital integration and more consistent precision. What is Levelling in surveying?
Levelling in surveying. Levelling is a process of determining the height of one level relative to another. It is used in surveying to establish the elevation of a point relative to a datum, or to establish a point at a given elevation relative to a datum. Who invented the Total Station? The total station was first introduced to surveyors under a variety of names, including electronic tacheometer and EDM theodolite. How do you do a total station survey?
