Total stations are electronic devices used for accurate land surveying, measuring angles and distances using optical equipment and mathematical formulas. They can be operated manually or remotely and require only one person. Some models include satellite navigation, but their accuracy is debated.
Total stations are types of electronic equipment that make it possible to accurately estimate the slope distances between the location of the stations and a specifically located geographical point. Devices of this type can be operated manually on site or controlled via remote access. A total station’s ability to provide accurate measurements, including land slope, is invaluable to the land surveying process for future construction projects and a variety of scientific applications.
The function of a total station involves the use of electrical components including optical equipment as part of the measurement process. As part of collecting measurements, the device allows you to measure angles and distances to complete surveying tasks. The internal calculation of coordinates involves the use of formulas related to trigonometry and triangulation, both essential mathematical strategies common to this type of measurement process. In many cases, the link between the station location and the endpoint for evaluation is established through the use of microwave transmissions or some other type of infrared signal which enables the device to locate the reflector located at the opposite point. .
One benefit of using a total station is that the device can be used by a single surveyor rather than requiring two people to be present. The main unit can be placed in position, allowing the operator to walk to the opposite point of the area to be measured. While using a reflector to allow the total station to lock onto that target point, the operator can use a remote control to initiate and monitor the data collected and the resulting feedback derived from processing that data. This is in contrast to methods used in the past which required a minimum of two people to handle the process. In addition to minimizing the number of people needed to complete a project, the total station also produces calculations and data that would have been processed manually in the past.
There are also equipment options for total stations today that allow for the inclusion of a navigation system capable of interfacing with satellites. This addition allows measurements and other relevant data to be collected even if the point of origin and point of destination are not in direct line of sight. There is some controversy surrounding the use of this type of approach, as the calculations take longer and some professionals question the accuracy of the data obtained using satellite technology.
