The telescope also has a built-in electronic theodolite that measures the horizontal and vertical angles to the
target. The total station’s computer receives the data from both the EDM and the theodolite and processes it to
give the user the information they need. The total station can also have the capability to store data on the
instrument, allowing for easy transfer to a computer or other device for further analysis. Some total stations
can also be controlled remotely, allowing the user to take measurements from a safe distance.
Some total stations have the capability to connect to external devices such as GPS receivers, which allows for the integration of total station
data with GPS data, providing a more accurate and detailed survey. This feature is especially useful for
large-scale projects where a high level of accuracy is required.
There are different types of total stations, and they can come with different features, such as robotic total stations, which are able to move the telescope and
rotate the instrument to a new point with just one button press. They also have a built-in robotic controller,
which allows the instrument to be controlled remotely from a data collector. This feature is especially useful
for larger projects where multiple measurements need to be taken from different positions. Another example is
the 3D total stations, which are able to measure angles and distances in three dimensions, providing users with
a more complete picture of the area being surveyed.
Manual Total Stations
Manual total stations are the traditional type of total station that has been used for many years. They are
operated by a human surveyor who manually points and shoots the instrument at each point to be measured. The
surveyor then records the angle and distance measurements, which are then used to calculate the coordinates of
the point.
One of the main advantages of manual total stations is their simplicity. They are easy to use and require
minimal training. They are also relatively inexpensive, making them a good option for small-scale projects or
for surveyors on a budget. However, manual total stations have some limitations. They are slower to operate than
robotic total stations, and they are more prone to human error.
Robotic total stations, on the other hand, are operated by a robotic arm that automatically points and shoots the instrument at each point to be measured. The surveyor controls the instrument remotely, using a computer or a handheld controller. This allows the surveyor to remain at a safe distance from the instrument and to take measurements from a more convenient location.
One of the main advantages of robotic total stations is their speed and efficiency. They can take measurements much faster than manual total stations, and they are less prone to human error. This makes them a good option for large-scale projects or for surveyors who need to collect a lot of data quickly.
Another advantage of robotic total stations is their flexibility. They can be used in a variety of environments, including challenging or dangerous locations, and they can be programmed to take measurements at specific intervals or to follow a predetermined survey plan. They can also be integrated with other equipment, such as GPS or laser scanners, to provide more accurate and detailed data.
However, robotic total stations also have some limitations. They are more expensive than manual total stations, and they require more training and expertise to operate. They are also more complex and require more maintenance than manual total stations.
